BACK progressive springs are somewhat progressive, but under more compression change traits to become more linear. This gives exceptional feedback through the automobile in various track conditions. Marked with 3 dots for simple identification. Group of 2.
Available as a pair, the springs are independently measured, managed, inspected, and matched to produce identical damping faculties. Throughout the selection process, each springtime is compressed in a number of fine increments plus the values recorded, and then each spring is matched with another spring of identical characteristics. XRAY goes the excess mile to make sure perfect spring fits, giving your vehicle the predictability and persistence that you need to help you lead the pack.
