ST XA height-adjustable coilover kit for the 8V Audi A3 and S3 Quattro, built by hand by KW in Germany and dyno-tested before shipping. Ride height adjusts via a friction-optimized polyamide composite spring perch with a stainless-steel insert, and rebound damping is set with 16 distinct clicks to tune the car between comfort and sport. Galvanized zinc-coated steel struts, a dust protection system, and a multi-layer sealing package protect the hardened chrome piston rod for long-lasting use.
