New FRONT progressive springs are slightly progressive, but under more compression change characteristics to become more linear. This gives an excellent feeling & feedback of the car in all different track conditions. Marked with THREE dots for easy identification. Set of 2.
Available as a pair, the springs are individually measured, controlled, inspected and matched to provide identical damping characteristics. During the selection process, each spring is compressed in several fine increments and the values recorded, and then each spring is matched with another spring of identical characteristics. XRAY goes the extra mile to ensure perfect spring matches, giving your car the predictability and consistency that you need to help you lead the pack.
