The ST X coilover kit delivers height-adjustable, fixed-damping suspension developed by KW for the everyday driver who wants a lower stance without sacrificing road comfort. Galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting ride-height adjustability, while the hardened chrome piston rod runs inside a pressure-resistant damper housing with a multi-layered sealing package. Dampers and spring rates are tuned in Germany for this specific application and each unit is hand-built and shock-dyno tested by KW in Fichtenberg, Germany.
