When adjusting front suspension, the XRAY 348188 Progressive Front Shock Springs C=7-9 help produce a controlled compression curve that improves steering response and reduces unwanted roll. These springs suit drivers who alter setups to match changing track grip.
The progressive curve means the spring starts around C=7 and increases stiffness toward C=9 as it compresses, offering a compliant entry and firmer support later. That progression helps keep steering predictable while limiting excessive body movement in the middle of a corner.
Pairs are inspected and matched for rate and length to ensure consistent behaviour. Laser marks on the top coil identify the rate quickly, making it easier to test different spring combinations during setup sessions.
