For hobbyists refining their setup, the XRAY 388091 Shock Spring Set rated C=2.25 provides a reliable medium spring rate. These springs are firmer than typical kit pieces but maintain enough give to help the tyres stay planted across mixed surfaces.
The XRAY 388091 springs are engineered to strike a compromise between softness and stiffness, helping to stabilise the car without making it skittish. That balance helps when you need predictable handling through varied track sections.
Suitable for a range of damper types, these medium springs make a straightforward upgrade from stock springs. Fitting the XRAY springs can improve front end response and reduce unwanted body movement.
