The ST XA coilover kit delivers ride-height and rebound-damping adjustment for the Audi A4 and S4 (B5). Sixteen distinct clicks of adjustable rebound damping let you tune driving dynamics from comfortable to sporty, while the friction-optimized polyamide composite spring perch with a stainless-steel insert makes height adjustment smooth and corrosion-free. Galvanized zinc-coated steel struts and a multi-layered sealing package with dust protection provide long-lasting corrosion resistance. Built by hand by KW in Fichtenberg, Germany, and dyno-tested before boxing.
