General
The COM Sports Car Club is a not-for-profit organization with membership open to any person interested in sports cars
and sports car events. The overall goals of COMSCC's Driver Schools and Time Trial Event are to:
1) Conduct a track event that puts everyone’s safety first.
2) Provide a driving instruction program that allows drivers to acquire and develop skillful driving techniques for
enhanced driving pleasure and improved competitive ability.
3) Provide a time trial competition format that rewards both speed and consistency and includes a trophy class for
every car that wishes to compete, provided it meets the safety requirements outlined in these rules.
4) Maximize track time.
COM time trials are run in the spirit of good sportsmanship and are designed to provide competition for sports cars,
racing cars and sedans. Entrants are not guaranteed competitiveness for any vehicle in any class.
Cars may move between 10 total classes (including 7 Touring classes and 3 Super classes) provided they meet all the
specific rules (including safety rules) of the class into which they wish to move.

Entry Procedure
1) To enter a COM event, entrants must be a current member of COMSCC in good standing, and hold a valid
drivers’ license issued by the state or province in which they reside. Each entrant must fill out the appropriate
registration form in full and present it to the event Registrar along with the appropriate fees. On the morning of
the event, all entrants must present their drivers license for inspection by the Registrar.
2) Cancellation refunds are only given if the entrant has notified the registrar 7 days prior to the first day of the
event. Entrants who are registered for both days of a two day event and who experience a mechanical
breakdown on the first day which prevents them from participating on the second day, may obtain a refund for
the second day provided they notify the Registrar prior to the end of the first day.
3) A driver may enter two or more cars in one or more classes but must pay an entry fee for each.
4) A late entrant is one who shows up after trackside registration closes at 8:15am. The registration, tech
inspection, and actual running of a late entrant will be at the discretion of the event chairman (or chief
instructor during drivers' school). If allowed to run, a $25 late penalty fee will be charged to the entrant.
5
Driver Requirements
General
1) Drivers must be at least 18 years of age. Due to constantly changing insurance regulations and state laws,
drivers under 21 years of age may be required to produce a signed and notarized release form. Please contact
registration well in advance of event for further information and appropriate forms if necessary.
2) Anyone taking medication must so indicate on his/her entry form.
3) A Driver Competition Log (DCL) will be issued to each driver at his/her first event upon producing a valid State
Driver's license.
4) A driver will be classified as a student until his/her Driver Competition Log is signed by the Chief Instructor for a
license. Before being allowed to compete in a Time Trial, a driver must have a COMSCC Competition License or
be classified as “Safe to Solo” by his/her individual Instructor. “Safe to Solo” will apply to the one full practice
and time trial day following the school day.
5) Drivers and passengers must wear an Snell Foundation M or SA approved safety helmet at all times while on the
course. At least M2005 or SA2005 approval is required. Note –COMSCC’s policy is to update this rule every 5
years to ensure helmets are no more than 10 years old. For example, after the 2014 season, the approval dates
will be moved to M2010 and SA2010, respectively. COM reserves the right to reject for use any helmet that
appears damaged or otherwise unsafe.
6) In an open car, occupants must wear the following while on course:
a. Goggles or face shield; if vehicle is equipped with a stock windshield, eyeglasses, or sunglasses will be
accepted.
b. Arm Restraints
c. For the purposes of this rule, an “open car” is defined as a convertible, Targa, T-Top, or other vehicle
that has no solid roof structure as delivered from the factory (e.g. formula car, sports racer, etc.) An
open car with a soft top raised is still considered an open car.
d. An open car with a hardtop in place is considered a closed car for the purposes of this rule only
7) Occupants must wear, at a minimum, long sleeves (NOT NYLON), long pants and suitable footwear. Cleated
shoes, heavy boots and sandals are not permitted. Fire resistant suits and gloves and suitable footwear are
recommended in all cars. NYLON CLOTHING IS NOT ALLOWED.
8) Occupants of vehicles that are classified in a Super Class or have acquired 51 or more Touring Class Modification
Assessment points are required to wear a minimum of a single layer fire resistant full length suit and gloves and
suitable footwear.
9) At no time during the Time Trial or on-track session will passengers be allowed on the course unless one
occupant is a COM instructor or a person designated by the Chief Instructor. All occupants must be COMSCC
members, and registered for the event.
6
Passing
1) Passing is allowed only in those areas defined at the Driver’s Meeting.
2) Drivers being overtaken by other cars are expected to:
a. Remain on the racing line
b. Signal to the overtaking driver on which side he/she would prefer the pass to be performed
3) If the passing driver does not receive a point-by signal within a reasonable length of time, he/she may inform
corner workers with a “pit-in/catch” signal (closed fist extended outside the driver’s window). Corner workers
shall call Control upon acknowledgment of the signal and Control will then make a Black Flag decision, possibly
directing the unyielding driver into the pits for consultation.
4) A point-by signal is only an acknowledgment of the presence of the passing car and an indication of the
preferred side for the pass to take place. It is in no way a command for the passing driver to execute the pass.
The passing driver may not pass without having received a point-by. If the driver chooses to pass, they shall pass
on the side directed.
5) It is always the responsibility of the passing driver to execute a safe pass within the defined passing zone.
Should a driver execute a pass without having received a point-by and cause what is deemed by the Event Chair
as an unsafe situation, proper disciplinary actions will be taken.
Licensing
1) COMSCC Licenses are issued for an initial period of three (3) years. Following the initial three (3) year period,
licensed members must participate in at least one (1) COMSCC event per year to maintain an active license. At
the discretion of the Chief Instructor, members whose licenses have lapsed may be required to attend a
COMSCC event as a Student in order to reactivate their license.
2) The Chief Instructor may temporarily suspend or permanently revoke the COMSCC license of any member
whose driving or on-track behavior is considered a significant safety risk. License suspensions and removals may
be appealed in writing to the Board of Directors.
Pit & Paddock Conduct
1) Consumption or influence of alcoholic beverages and/or intoxicating drugs before the completion of the last run
of the day (or end of driver's school) will cause immediate disqualification. This rule includes drivers, crew,
officials, guests, and workers.
2) Unsafe, reckless, or unsportsmanlike driving or behavior anywhere on the course, in the pits, on the access
roads, or any other area within COM's jurisdiction is grounds for immediate disqualification.
3) All pets must be leashed at all times. Please check with the track to ensure they permit pets.
4) Shirts, long pants and shoes are required in pit lane and on track. Some tracks require helmets (e.g. bicycle
helmets) in the hot pits.
5) No one under 16 is allowed in the pits or on the track while the track is open.
6) A driver is responsible for the actions of his pit crew and guests, including 1, 2, 3, 4, and 5 above.
7) No cars are allowed to loiter in pit lane, unless permitted by the Chief of Control.
7
Car Requirements
Any vehicle or driver failing to comply with any item in Sections VI and VII below will not be allowed to run until the
failed items are corrected.
1) Tires and Wheels
a. Higher than normal inflation pressures are recommended for competition. Consult an Instructor if you
have any questions.
b. No cuts, bruises, ply separations, or body rubbing on the sidewalls is allowed.
c. All wheels must be free from bends or cracks.
d. Wire wheels will be rejected if they have more than two adjacent loose spokes or more than three total
loose spokes on a wheel.
e. Hub caps and trim rings must be removed.
f. All lug nuts must be in place and tight. It is recommended that nuts be torque to specification.
2) Brakes
a. Wheel bearings must have minimal play.
b. Brake fluid reservoir must be full.
c. Brakes must be capable of stopping the car quickly and in a straight line.
d. All vehicles are strongly recommended to run braided brake lines. COM drivers have experienced
failures with new OEM flex lines while on track. Ford Mustang Cobra 1994-1998 must not use “as
delivered” front flex lines.
e. Use of aftermarket cross-drilled rotors is discouraged.
3) Suspension
a. Suspension must be suitable for high speed cornering and handling. Loose, soft, or worn shock
absorbers, soft springs, sloppy ball joints, etc., are grounds for rejection of the car.
b. Drag racing suspension modifications such as car raising, "Up Loc" or similar weight transfer devices,
etc., are entirely unsuitable for controlled cornering and shall cause rejection.
c. Steering gear and linkage must have minimal play.
4) Engine Compartment
a. Engine compartment must be clean with no oil, water, or gas leaks. Hoses, lines, wiring and belts must
be in good condition and securely mounted. The battery must be securely mounted. Exhaust system
must be firmly mounted.
b. The use of nitrous oxide is prohibited in all classes. Cars having nitrous systems installed shall indicate
such on the pre registration form and tech sheet. The nitrous supply (bottle) shall be unhooked and
removed from the car. Removal shall be verified at tech inspection.
5) Automobile Exterior
a. Cars must be generally neat, clean, and suitable for the event.
b. All exposed headlights and glass lenses must be completely covered with tape. Plastic lenses need not
be taped. Clear tape is allowed. All cars must have operative and exposed brake lights, except Super
Unlimited class cars. Super Unlimited class cars must have rain lights.
8
c. Removable hardtops may be removed and convertible tops may be lowered. T tops on 914s, X1/9s,
Corvettes, etc., will be allowed if they are structurally sound. Tonneau covers or any soft removable
cavity cover must be removed.
d. All cars, except Super Class cars, must be equipped with a full height and width windshield. Side
windows will be all the way open unless noted at the drivers meeting. Window nets are highly
recommended.
e. Car numbers and class must be placed on both sides of the car before Tech Inspection. All markings
must be easily readable by corner workers. Numbers must have a minimum height of six (6) inches.
Class designations must have a minimum height of 3 inches. Numbers and class designation shall be on a
vertical side panels or vertical side windows and shall be of contrasting color to the car. Novice drivers
will place three vertical stripes on each rear quarter panel and trunk lid. Magnetic numbers are
permissible provided they are secure to the vehicle, which is the responsibility of the driver of the
vehicle.
6) Vehicle Interior
a. All loose gear must be removed before coming to Tech Inspection. If (the) spare tire is carried in the car,
it must be firmly secured. Passenger seat back must be tied down or secured in position.
b. All cars must have well mounted, metal-to-metal, quick release lap and safety belt and upper body
restraint in good condition. Mounting points must be sturdy and immovable locations on the chassis,
unibody, or roll cage/roll bar/harness bar. Suitable backing plates should be used where necessary.
Refer to manufacturers, FIA and/or SFI mounting specifications for more information regarding
hardware, backing plate, and installation requirements and suggestions. Touring Class cars may use any
DOT, SFI, or FIA approved harness. Super Class cars, any car that has acquired 51 or more Touring Class
Modification Assessment points, or any car that has removed front airbag(s) must use an SFI or FIA
approved harness with a minimum of 5 points (2 lap belts, 2 shoulder belts, and at least 1 antisubmarine belt).
i. All harness belts must have the SFI or FIA date certification label and be current (i.e. not expired
or out of code). Generally, SFI belts are certified for 2 years and FIA belts are certified for 5
years. Certification date begins as of the date of manufacture, not the date of installation into
the vehicle.
ii. When constructing bars for harness attachment, be aware of the potential safety hazard that
can be created by the addition of a horizontal bar directly behind the driver’s seat. In the event
of a rearward impact the driver’s seat can be broken allowing the occupant(s) to impact the
horizontal bar resulting in serious or fatal neck injuries. Suggestions for avoiding this potential
hazard include moving the horizontal bar as far to the rear of the car as possible, utilizing a
mount that is direct to an existing portion of the car or installing a full roll bar with an upper seat
support.
c. If the passenger seat is to be occupied, its seat belt restraint system shall have equal or greater restraint
capability to the drivers’ seat belt restraint system, including type, width, and number of points. This is
to ensure that the passenger is not subjected to aggressive driving that the driver would be willing
subject himself to, based on the level of driver seat belt restraint. For the same reason, any driver using
a arm or head and neck restraints must also provide the same for the passenger.
9
d. Novices and other students not yet licensed by COM must train in a vehicle possessing a minimum of
two seats and safety equipment for both seats appropriate to the class, of which one seat is to be
occupied by an approved instructor.
e. Roll bars are required in all Super Class cars or cars that have acquired 51 or more Touring Class
Modification Assessment Points and in all convertible and open cars regardless of class. Roll bars are
permitted and strongly recommended in all classes and may be required in the future. A roll bar is a
steel one- or two-hoop roll-over protection device, solidly mounted to the structure of the car, and
provides two inches of space between the top of the roll bar and the top of the driver’s helmet.
Commercially available “harness bars” and “style bars” are not acceptable roll-over protection.
i. Factory installed roll-over protection on open cars is not acceptable. Specifically, the Porsche
Boxster or Boxster S/993/996 convertible system, the Honda S2000, and Mazda MX-5 Miata
factory equipment are not acceptable for competitive use. Convertibles may not use removable
hardtops as a substitute for roll bars. A competitor may appeal to the Chief of Tech for
acceptance of factor-installed OEM roll-over protection. The decision by the Chief of Tech is
final.
ii. Guideline minimum roll bar specifications are:
iii. Cars up to 1500 lbs use 1.375 x 0.095 DOM/seamless/alloy
iv. Cars 1501-2200 lbs. use 1.500 x 0.095 DOM/seamless/alloy OR 1.500 x 0.120 ERW
v. Cars 2201-3000 lbs. use 1.500 x 0.120 DOM/seamless/alloy OR 1.750 x 0.095
DOM/seamless/alloy OR 1.750 x 0.120 ERW
vi. Cars 3001-4000 lbs. use 1.750 x 0.120 DOM/seamless/alloy (no ERW allowed)
vii. For guidelines of material selection and construction practices, consult the Sports Car Club Of
America (SCCA) General Competition Rules. Cars with roll cages that are constructed to SCCA
GCR or other recognized sanctioning bodies’ specifications are not bound by the material
selection criteria mentioned above.
viii. All roll cages/bars must be padded with non-resilient material such as Ethafoam or Ensolite with
a minimum thickness of ½” in all areas which may come in contact with the driver’s and/or
instructor’s helmet. Similar padding is recommended in areas where the driver’s and/or
instructor’s arms or legs may come in contact with the roll cage/bar.
f. In all classes, interior panels, trim, and carpets may be modified or removed to the extent required to
accommodate roll bars, roll cages, or other safety equipment. This includes the modification or removal
of door panels, window glass and lift mechanism to accommodate roll cage door bars. Note – the
addition of a roll bar or roll cage and/or removal of interior and other components may affect the
Competition Weight. See Classification section for details.
g. Helmets must be a minimum of 2 inches below the top of Targa Top vehicles.
h. Window nets are permitted in all classes. In addition, for all Super Class cars or cars that have acquired
51 or more Touring Class Modification Assessment points, either window nets or arm restraints are
required.
i. The following safety equipment is allowed in ANY class:
i. Fire extinguishers and fire systems
ii. Master electrical kill switches
iii. Fuel cells
iv. Windshield/window clips and restraints
10
v. Towing Hooks
vi. Flywheel scatter shields
7) Miscellaneous
a. Automobiles involved in an incident causing damage must be inspected by Scrutineering before being
allowed back on the track.
b. All in car video equipment must be inspected and approved by Tech.
c. Track imposed maximum sound limits will be in effect at COM events for all classes. Sound limit at all
tracks is 99 Db or less at 50 feet while under power on the track. Each competitor is responsible for
meeting track-specific sound limits. For Time Trials, a noise violation results in disqualification with no
points awarded for the event and no refund.
8) All cars shall be powered by gasoline, diesel fuel, biodiesel fuel or electricity (provided by batteries) alone or in
combination. Gasoline may be leaded or unleaded. Gasoline may include race gas limited by the SCCA fuel GCR
to prevent toxic chemical use. Pump gasoline including Methyl or Ethyl Alcohol (Methanol or Ethanol) as limited
by SCCA GCR may be used. Methyl or Ethyl Alcohol as a primary fuel is prohibited. Small amounts of Methyl or
Ethyl Alcohol may be injected into the engine for engine cooling and detonation control when mixed with at
least 50% water. No more than 1 gallon of such mix shall be carried in the car to ensure that it is not a primary
fuel. Whenever an alcohol/water mix is injected into the engine it shall be considered a fuel and the tank must
follow the same rules as other fuels
11
Flags
1) Command Flags
a. GREEN Course is clear.
b. STATIONARY YELLOW No passing! There is a problem on the course ahead of you. Proceed with
caution. During timed runs, you are still being timed.
c. WAVING YELLOW No passing! There is a problem immediately ahead of you. Slow down. Drive
carefully; prepare to take evasive action. During timed runs, the clock will stop and you will be allowed
a re run.
d. RED Stop now! Stop in a controlled manner before the next flag station. Watch your mirrors while
stopping to avoid being hit from behind. If possible, get clear of the course to allow passage of
emergency vehicles. Stay stopped and in your car until given a standing yellow flag and then proceed
slowly back into the pits.
e. BLACK Pull into the pits immediately for conference with authorized personnel who will make
themselves known to you. There is something wrong with you or your driving. This flag may be used to
end a practice session.
f. BLACK FLAG WITH ORANGE CENTER (Meatball) Pull into the pits; there are mechanical problems with
your car that must be corrected before you can continue. You must receive clearance from the Tech
Inspector or Starter before returning to the course. During timed runs this is a did not finish (DNF).
g. CHECKERED You have completed your timed run or practice session. Continue your lap and pull into
the pits.
2) Informational Flags
a. DIAGONAL RED AND YELLOW STRIPES (oil or debris) Slippery track conditions. Caution.
b. WHITE Caution: Emergency, official vehicle, or competitor vehicle at slow speed on the course. The
vehicles being protected by the white flag may be passed provided the pass is done in a safe manner.
c. BLUE (blue with diagonal yellow stripe) Another vehicle is catching you and/or following closely. Be
aware! Do not change your line. If the vehicle is faster than you, it is recommended that you indicate
which side you prefer to be passed on by motioning with your hand in that direction.

Time Trial Points & Guidelines
1) COMSCC championship series time trials consist of several events during the course of the year. This series will
be based on a cumulative points system where points are earned by participating and placing in events as
follows:
a. 2 points for participating in the events plus:
1st place
9 points
2nd
7
3rd
5
4th
3
5th
2
b. To receive participation points, the competitor’s vehicle must cross the designated Start-Finish line,
provided that the time trials are completed. If the event is held, but time trials are canceled or can’t be
completed, every competitor shall receive participation points. To receive finishing points, the
competitor’s vehicle must complete a minimum of one timed lap.
c. At the end of the year, additional points (including fractions) equal to the average number of cars per
event will be added to the points of each class winner to determine the Overall Driver Championship.
The Board of Directors may, from time to time, assign additional points to given events, to encourage
participation in those events. These points will be assigned before the first event of the season.
d. Ties in the final point totals shall be resolved on the basis of each participant’s record of First Place
finishes: then if necessary, Second Place finishes: then if necessary, Third Place finishes, and so on until a
winner emerges. If this procedure fails to produce a result, they shall be considered tied for the position
in the standings.
2) An entrant must be a member of COMSCC to participate in a Driver’s School or Time Trial. In order to be eligible
for year-end Class Championship (1st, 2nd, 3rd, or 4th), a driver must have entered at least (3) events during the
current year in the same class. in addition, for any Class Champion to be eligible for the Overall Driver
Championship, that class must have an overall average of 2.0 or more participants per event for the season.
3) There may be no more than two drivers for a particular car in a particular class participating for trophies.
Additional drivers may run, but not for trophies or for points in class. The contending drivers must be made
known at Registration.
4) Trophies will be awarded at COM events as follows:
1, 2, or 3 car class
1 trophy
4 or 5 car class
2
6 to 9 car class
3
10 to 14 car class
4
15 to 19 car class
5
20 or more car class
6
5) Year-end trophies will be awarded on car class average as follows:
Less than 4.0
1 trophy
Greater than or equal to 4.0 to less than 6.0
2
Greater than or equal to 6.0 to less than 12.0 3
13
Greater than or equal to 12.0
4
6) The driver completing all 3 time trial laps whose lap times are within a smallest range will receive the
Consistency Award for the event.
7) In a single event, drivers may count only one car in each class for points. Points earned in each class may count
towards the Class Championship for that class. Points from only one class finish during that event may be
counted towards the Overall Driver Championship.
8) If the event is canceled (i.e. we never get on the track) due to circumstances beyond the control of COM Sports
Car Club (e.g., weather and/or track conditions), no points will be awarded. Should an event be delayed or
canceled, COM is not required to provide a refund nor should a participant expect to receive a refund. However
COM will make every effort to provide a partial refund for any funds in excess of the overhead costs incurred by
COM Sports Car Club.
9) A Time Trial run is considered completed if all cars scheduled to run have completed their timed runs. All
competitors submitting time cards to Gridding are scheduled to run unless Gridding is notified by the competitor
of a DNS status. Should an event be closed for any reason, the determination of which cars are scheduled to run
will be based on the information Gridding has at the time of the conditions causing the event to close.
10) If an event is closed for any reason before all Time Trial runs are completed, then the event will be considered
11) canceled. All participants will receive participation points as if the Time Trial had been completed. Classes in
which all cars scheduled to run completed at least one of their timed runs prior to the event being closed will
12) Receive their respective class points in addition to their participation points, but these points will not count
toward the Overall Driver Championship.
13) Only times taken by Timing and Scoring during Timed Runs will be considered for a class record. Competitors
who believe that they have set a new class record must present their car to Scrutineering for inspection , to
verify compliance with class requirements. Information necessary to show original configuration (shop manual)
is the competitor’s responsibility. If the car is found to not comply with the rules for that class, the record will
not be awarded, and the car will be disqualified. The Points Keeper will record the lap records.
14) Any car exceeding the maximum decibel limit of the track where the time trial is taking place shall be
disqualified. No points shall be awarded to the driver(s) of disqualified vehicles. The driver may appeal this
decision to the BOD prior to trophy presentation ceremony if the noise violation was that cars first
offense/warning of the event.
15) An entrant may appeal a decision made by a Chief of Specialty in writing to the Board of Directors. This appeal
must be made within 7 days following the date of the decision being appealed. The Board of Directors will vote
on the appeal at the next Board Meeting and deliver their decision to the entrant. Affected parties who are
Board members or Officers of the club are not permitted to vote on the appeal.
16) A particular Car/Driver combination is only allowed one time trial attempt (excluding catches). If a Car/Driver
doesn’t arrive for staging, or the Car/Driver leave the track for any reason (such as a pit entry for mechanical),
they will be scored according to the time trial rules. The Chief of Timing and Scoring may add cars/driver to new
or existing run groups or change run group order at its discretion.
17) If a competitor causes a catch due to driver error, they will be disqualified. An example, but not limited to,
would be a car that spins off track, then enters the track again, causing the car behind them to catch them.
18) If a competitor causes cars to become out of order, they will be disqualified. An example, but not limited to,
would be a car that spins off track, and then enters the track again, after other cars have passed.
14
19) If a mechanical failure or driver error (as determined by Chief of Control or Chief of Timing and Scoring) causes
the time trial to be stopped, that driver will be disqualified, and the remaining drivers will get a re-run.
20) Disqualification of a competitor for any reason must occur before the trophy presentation ceremony at the end
of the time trial day, or by the end of the time trial day in the event that no presentation ceremony is held.
15
Classification System
Definitions
Corrected Power-to-Weight – for determination of classification within Super Classes, the sum of a vehicle’s weight-topower ratio and any corrections allocated for absolute vehicle weight, tire used, and drivetrain layout/classification
Factory Trim – refers to unmodified vehicle components (or components of an identical fit, function, and purpose)
included on the car year, make, model, and body style listed for purposes of the Showroom Assessment as delivered by
the manufacturer within the respective domestic market; Example- a 1965 Mustang is bought with a standard 289 2 bbl
carbureted engine. The owner then replaces the 2 bbl carburetor, cast iron intake, and 2 bbl heads with Ford OEM 4bbl
carburetor, aluminum intake manifold, and High Performance heads as used on the Hipo Mustang and Shelby. These
parts were available “overthe counter” at the Ford dealer, not just as part of a new car, so a claim that they are “factory”
could be made. However, as these parts were not on this car as it left the factory, points for Non-Factory carb, intake,
and heads must be taken
Modification Assessment – total number of assessment points pertaining to non-Factory Trim modifications to a vehicle;
see Modifications Assessments section of the rules for points assessed for each modification – for modifications not
explicitly listed in the Modifications Assessments section of the rules, points for each modification will be provided by
Scrutineering
Showroom Assessment – point value assigned to each car for the purpose of classification within Touring Classes; see
Appendix A and B for list of Showroom Assessments – for vehicles not explicitly listed in Appendix A and B, Showroom
Assessment will be provided by Scrutineering
Showroom Base Weight (SBW)– factory listed curb weight for a production vehicle; used in determining the appropriate
number of Modification Assessment points for cars competing in a Touring Class
Super Class – a type of COMSCC Time Trial classification where vehicles are classified based on weight-to-power ratio
with corrections for absolute vehicle weight, tire used, and drivetrain layout/classification
Total Assessment – the sum of the Showroom Assessment and Modification Assessment, used to determine
Classification within Touring Classes
Touring Class – a type of COMSCC Time Trial classification where vehicles are classified based on the sum of a Showroom
Assessment based on the vehicle’s potential and a Modification Assessment for any modifications performed to the
vehicle
Vehicle Competition Weight – the total weight of vehicle plus fluids, driver, ballast and any and all safety and other
equipment during competition
16
Overview
COMSCC Time Trial includes 10 distinct classes for competition, 7 Touring classes and 3 Super classes. Vehicles are
classified into a Touring class based on the Total Assessment, comprised of a benchmark Showroom Assessment plus
any additional Modification Assessments acquired through performance modifications added to the vehicle. Vehicles
are classified into Super classes if a vehicle’s Total Assessment exceeds the Maximum Class Assessment of the 7 Touring
classes. Classification within Super classes is determined based on a Corrected Power-to-Weight ratio. Typically race
cars and highly modified street cars are suited for Super Classes, where most production cars compete in Touring
Classes.
Classification Procedures
1) Prior to competing in a Time Trial, each entrant must submit to Scrutineering a classification sheet prior to the
close of Tech. Inspection on the day of the Time Trial – Scrutineering will collect and make competition sheets
openly available to all entrants
2) Entrants are solely responsible for proper classification of their own vehicles. New competitors may receive
classification assistance at Tech Inspection from Scrutineering, but are highly encouraged to contact the Chief
Scurtineer via email with questions well before the event to minimize delay on the day of the event. Whereas
vehicle class is most important from a competitive perspective on the second (time trail) day, Scrutineering is
available during the first day of the event to help answer specific questions as they arise. However, no event
official is responsible whatsoever for the proper classification of the vehicle.
3) Entrants are also responsible for policing of competing vehicles within their class. To insure that competitors are
classifying their cars within the rules of the club and to promote proper vehicle maintenance, a secondary
inspection by a Tech Inspector or Scrutineer may be done to a random sampling of cars in any class.
Scrutineering reserves the right to re classify a vehicle at any time. False information supplied by an entrant
about their car or themselves is grounds for disqualification. Inspection may include, but is not limited to:
a. Inspection of vehicle components and modifications
b. Weighing of vehicles
c. Request for additional documentation to substantiate horsepower, torque, or weight claims, if scales
are not available; Scrutineering will consider any and all documentation available, including scale
printouts, dyno sheets, spec sheet for “sealed” or “crate” motor, list of engine modifications, etc. If
documentation is not available upon request, Time Trial results may be determined “provisional” until
the requested information has been provided to a scrutineer.
4) All protests must be presented verbally or in writing by the entrant to a Scrutineer. No classification protests
affecting a given event will be accepted after the end of the last time trial run of that event.
5) Protests may only be filed by event competitors of the same class, Scrutineers, and Event Chairpersons. Event
competitors can protest the classification of a car participating in another class that he or she believes is
incorrectly classified and should be competing in their class.
6) If a competitor is protested and it is found that the competitor’s car is not legal in the previously declared class,
the competitor will be automatically re-classed to the proper class, as determined by Scrutineering.
7) A competitor may appeal a Scrutineering decision in writing to the Board of Scrutineers. This appeal must be
made within 7 days following the time of the protest in question. The complete Board of Scrutineers will vote
17
on the appeal and deliver their decision to the competitor before the next time trial event. This decision may
not be appealed to the Board of Directors.
8) Any discrepancy in the classification of a car between the vehicle tech sheet, timing card and class displayed on
the vehicle will result in disqualification. It is the responsibility of each entrant to verify the accuracy of this
information and correct any discrepancies with Registration and Timing and Scoring prior to submitting a time
card. Participation points will be awarded to disqualified cars in the proper class.
9) Any track record must be validated by having a Classification Sheet inspected by Scrutineering after a
competitor’s time trial run but before the conclusion of the event. Upon review of the competitor’s
Classification Sheet, the scrutineer may determine that additional inspection of the vehicle is required – see #3
above for details. If the car is found is not legal in the previously declared class, the competitor will be
automatically re-classed to the proper class, as determined by the Scrutineer, and will receive event and season
points only in the newly determined class.
18
Touring Classes
To compete in a Touring class, a vehicle must be a production vehicle with closed fenders, and in Factory Trim, approved
by the US DOT or equivalent organization.
The process for determining the classification of a vehicle is threefold:
1) All vehicles must be assigned a Showroom Assessment, either through the Showroom Assessment Inventory
(Appendix A) or provided by the COMSCC Chief Scrutineer prior to event registration. Generally, the Showroom
Assessment Inventory uses the following methodology for assigning Showroom Assessment points to vehicles:
a. Determine the weight-to-power ratio of the vehicle using factory listed curb weight, factory listed crank
horsepower, and factory listed crank torque
i. Formula: Curb Weight / (2/3 x HP + 1/3 x Torque)
b. Convert the weight-to-power ratio to an meaningful points value for classification within Touring Class,
this is achieved by multiplying the ratio by -4.25 and adding 114; these factors were chosen to:
i. Create a proper distribution of vehicles across the 7 Touring Classes based on weight-to-power
ratio, and
ii. Ensure that the highest performing domestic production vehicles are classed towards the top of
the Touring Class structure
c. Add an “adjustment” to the converted weight-to-power ratio to account for other factors that affect
vehicle performance, such as suspension, weight distribution, drivetrain layout, aerodynamics, etc.
Generally these assessments range from -10 points (e.g. Subaru Forester Wagon) for cars that have a
significantly lower performance potential relative to their weight-to-power ratio up to +15 points
(Nissan GT-R) for cars that have a significantly greater performance potential relative to their weight-topower ratio – See Appendix A, “Adjustment” column, for the adjustment on each car
d. The sum of b (converted weight-to-power ratio) and c (additional performance “adjustment”)
represents the total Showroom Assessment
2) In addition, a Modification Assessment must be determined by summing the total points acquired for the
following:
a. Any modification to the vehicle that differs from Factory Trim
b. Vehicle Competition Weight, if below Showroom Base Weight, and
c. Tire width, if different from the Touring Class Standard Tire Width for the Touring classification of the
vehicle’s Showroom Assessment
3) A Total Assessment is calculated based on the sum of the Showroom Assessment and Modification Assessment,
and then classification is determined based on the table below. Vehicles with 100 or fewer Total Assessment
points will be classified into a Touring Class according to the table below. Vehicles acquiring more than 100
Total Assessment points will be classified in a Super Class.

For example: a vehicle with a Showroom Assessment of 57 and Modification Assessment of 8 would result in a Total
Assessment of 65 and classification in T60.
Note – a competitor may choose to compete any Touring class either at or above their determined Touring class (i.e. run
“up” a class); in addition, any Touring class competitor may opt to run in the appropriate Super Class (see separate
section below for classification guidelines)
Showroom Assessment – see Appendix A
For kit cars or race cars not listed in Appendix A, a competitor may request a Scrutineer-provided Touring Class
classification. In these instances, the competitor must provide the peak horsepower, peak torque, curb weight, and
other relevant technical specifications for the vehicle, as requested by the Scrutineer. There is no guarantee that
Scrutineer-provided Touring Class classifications will result in placement in a Touring Class – i.e. the Scrutineer may
decide to assess more than 100 Touring Class points, resulting in a Super Class classification for the vehicle in question.
Modification Assessments
Engine
The Modification Assessment for engine modifications can be determined in 2 ways, either:
1) Competitor adds points for any and all assessments listed below – to be added to the Showroom Assessment
and Modification Assessment points from other categories (e.g. suspension, brakes, etc.) to determine the total
assessment. Or,
2) In lieu of adding points from the assessments listed below, prior to the close of event registration the
competitor can opt to provide to the Scrutineer with a peak horsepower and torque figures, indicating wheel or
flywheel horsepower. The Scrutineer will then use the following process to assign a total number of engine
Modification Assessment points to the competitor using the following process:
a. If necessary, estimate crank power by converting all wheel power figures (horsepower and torque) to
crank power figures, assuming 18% drivetrain loss for 2wd cars, 20% drivetrain loss for 4wd cars. The
formula to convert wheel power to crank power is Wheel Power / 0.82 = Crank Power for 2wd, Wheel
20
Power / 0.80 =Crank Power for 4wd. If using Dyno Dynamics Shootout Mode figures, no conversion to
crank power is necessary.
b. Apply the same showroom assessment base class formula (described above) and appropriate
Adjustment (same as original adjustment used for competitor’s vehicle during base classing) used to
determine the showroom assessment while substituting the new power figures to determine a new
assessment
c. Determine the difference between the new assessment and original showroom assessment
Note - The competitor will not need to add any additional points for engine modifications from the list below.
The competitor, upon receipt of the new engine Modification Assessment figure, may still opt for option 1 at their
discretion
In the case of option 2, the Scrutineer-provided Assessment for engine modifications is final and may not be appealed.
In either case, any and all Modification Assessment points for other areas (e.g. suspension, weight reduction, tires, etc.)
must be added to calculate total Modification Assessment points.
In some cases, specifically involving engine modifications not listed below and engine swaps, the Scrutineer may require
a Scrutineer-provided Assessment. In these cases, the competitor must provide peak horsepower figure(s), and use of
this Assessment is not optional, i.e. the competitor may not use an Assessment based on engine modifications as listed
below.
Example: a competitor has a 1995 BMW M3 with 6 points worth of Engine Modification assessment points. They choose
to request a Scrutineer-provided engine Modification Assessment, providing to the Scrutineer their peak wheel
horsepower and torque figures of 245hp and 240ft-lb, respectively, along with any supporting documentation, if
requested. The Scrutineer then provides an assessment of 9 points based on the peak power figures. The competitor has
a choice – accept the 6 points from the table below, or accept the 9 points provided by the Scrutineer. Either way, the
competitor must still add the figure chosen, along with Modification Assessment points for other categories (e.g.
suspension, tires) to the Showroom Assessment to determine the Total Assessment for classification.
Example: a competitor has a 1991 Mazda Miata and has chosen to swap a stock 1996 Mazda Miata 1.8L motor. This
modification requires a Scrutineer-provided engine Modification assessment, and the competitor cannot choose to use
the points from the table below. In this case, the Scrutineer determines the base class of the 1991 Miata to be 30.3.
Substituting the new power figures (128hp, 114ft-lb torque), the new assessment is 39.1. The scrutineer finds the
difference between the 2 figures, and provides an assessment of 8.8 points for engine modifications. Again, the
competitor must add the 8.8 points engine Modification Assessment figure to the Showroom Assessment, along with
Modification Assessment points from other categories (e.g. suspension, tires) to determine the Total Assessment for
classification. Note – the competitor must still use the 1991 Mazda Miata base tire width and base weight, which is
listed as 170lb lighter compared to the 1996 Mazda Miata donor vehicle. This weight difference is worth approximately
up to 4 points in terms of Weight Reduction Modification Assessment.
Example: a competitor has a 2002 Subaru Impreza WRX with 19 points worth of Engine Modification assessment points.
They choose to request a Scrutineer-provided engine Modification Assessment, providing to the Scrutineer their peak
wheel horsepower and torque figures of 265hp and 275ft-lb, respectively, along with any supporting documentation, if
21
requested. The Scrutineer then provides an assessment of 16 points based on the peak horsepower figure. The
competitor has a choice – accept the 19 points from the table below, or accept the 16 points provided by the Scrutineer.
Either way, the competitor must still add the figure chosen, along with Modification Assessment points for other
categories (e.g. suspension, tires) to the Showroom Assessment to determine the Total Assessment for classification.
Note – Mazda Rotary Engines are to be considered 4 cylinder engines for the purposes of Engine Modification point

Tire Width
Tire Width Modification Assessment is based on the width of the widest tire run during competition. Competitor must
determine Tire Width Modification Assessment using the table below to determine the Showroom Assessment Class
Baseline Tire Width. From there, points will be assessed based on how much wider or skinnier the competitor’s widest
tire is from this Baseline Tire Width. Note – tire diameter and profile are free. Stock or factory Trim tire width for a
particular vehicle is irrelevant.

Assessment for tire width is based on the widest tire equipped on the vehicle. For example, if a vehicle is equipped with
225mm wide tires in the front and 255mm tires in the rear, the 255mm tire width will be assessed.
28
Add 2 assessment points for tire width of 20mm wider than Showroom Assessment Class baseline tire width from table
above (ex: for a vehicle in T60, add 3 points for 275mm wide tires). Add 3 points for 30mm wider, 4 points for 40mm, 5
points for 50mm, etc.
Subtract 2 assessment points for tire width of 20mm skinnier than Showroom Assessment Class baseline tire width from
table above (ex. For a vehicle in T80, subtract 4 points for 245mm wide tires). Subtract 3 points for 30mm skinnier, 4
points for 40mm, 5 points for 50mm, etc.
Add 1 assessment point for the following oversized tires: all Hoosier DOT-R and BFGoodrich DOT-R tires
Note – any wheel width and/or diameter is free, including offset and additional Non-Factory Trim spacers, provided that
the rim width used is among the rim widths recommend by the tire manufacturer for that particular tire size. Rolling
and/or flaring of fenders is also permitted. Non-Factory Trim lug nuts and studs are free.

Super Classes
Methodology
COMSCC has 3 Super classes, based on a Corrected Power-to-Weight ratio. Modifications allowed to cars in Super
classes are unlimited. In addition, any Touring Class vehicles with a Total Assessment of greater than 100 (i.e. above the
limit of T100) will be placed in a Super class. Competitors qualifying for a Touring class classification may choose to
compete in a Super class, provided
Note – this section outlines the competitive classification requirements for Super class vehicles. It does not outline
minimum safety equipment required to compete in a Super class. Refer to the Driver Requirements and Car
Requirements sections of the rulebook for specific safety requirements for Super classes, including driver clothing, roll
bars, harnesses, etc.
The Corrected Power-to-Weight ratio used in Super classes is based on the following factors:
1.
Competition Weight / Wheel Power – note wheel power = (2/3 x HP + 1/3 x Torque)
a. Wheel horsepower and torque of the vehicle, as attested to by the competitor; a dyno sheet may be
requested by the Chief Scrutineer at any time, but is not otherwise required upon registration
i. If necessary, convert all crank power figures to wheel power figures, assuming 18% drivetrain
loss for 2wd cars, 20% drivetrain loss for 4wd cars
ii. Formula for converting from wheel to crank is Crank Power x 0.82 = Wheel Power for 2wd,
