Characteristic
Ride &  Kx,Ky:High ⇒Self-steering effect
Handling
Using dual rubber compound.
 Kz : High ⇒Roll stiffness increase (Increase driving stability)
1) High Elastic rubber
(=Lower dynamic ratio )
 Vibration reduction : Low freq. + High displ. ⇒ High damping
2) High damping ( ≒13deg)
NVH
 Noise reduction: High freq. + Low displ. ⇒ Low dynamic stiffness
