The ST X coilover kit for 1999–2002 BMW Z3 M Coupe is tuned to add sharper handling while retaining usable street comfort and offers wide ride-height adjustability for fitment flexibility. It uses a friction-optimized polyamide composite spring perch with stainless-steel insert, galvanized zinc-coated housing, elastomer bump stops and a dust protection system to protect the piston rod and valves. Dampers are hand-built and dyno-tested by KW in Germany.
