For accurate front suspension setup, the XRAY 348188 Progressive Front Shock Springs C=7-9 provide a stepped compression characteristic that refines steering feel and curbs excessive roll during cornering. They are aimed at drivers who refine balance for lap consistency.
The C=7-9 progression means the spring behaves like a softer C=7 at initial travel and firms toward C=9 under heavier compression. This trait helps the car rotate cleanly into a corner and then resist over-compression as the load increases.
Each set includes two springs that are measured and matched to ensure similar performance between left and right. Laser-etched markings on the top coil let you verify the rate quickly when swapping springs during setup work.
