Brand new BACK progressive springs are somewhat progressive, but under more compression they change faculties to be more linear. This provides a fantastic feeling & feedback of car in most different track conditions. Marked with FOUR dots for simple recognition. Set of 2.
Available as moobs, the springs are separately measured, controlled, inspected and matched to present identical damping characteristics. Through the selection process, each springtime is compressed in a number of fine increments and the values recorded, then each spring is matched with another springtime of identical traits. XRAY goes the excess mile to ensure perfect spring fits, offering your car the predictability and consistency you need to help you lead the pack.
