The ST XA coilover kit for the Audi A4 and A4 Quattro (8E/B6-B7) combines a wide range of ride-height adjustment with 16-click adjustable rebound damping, letting you dial in both stance and driving dynamics. Each kit uses galvanized zinc-coated steel struts with a hardened chrome piston rod, a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-free height adjustment, and a multi-layered pressure-resistant sealing package. Built by hand by KW in Fichtenberg, Germany and dyno-tested to factory damper settings before shipping.
