The ST X coilover kit is an application-specific ride-height-adjustable suspension for the 1992-1998 BMW E36 3 Series (318i/318is/323i/323is/325i/325is/328i/328is sedan and coupe), tuned for the everyday driver who wants sharper handling without giving up ride comfort. Dampers and spring rates are tuned by ST's vehicle-dynamics engineering in Germany and built by hand at KW in Fichtenberg, with each damper shock-dyno tested. It uses galvanized zinc-coated steel struts for corrosion protection, a friction-optimized polyamide composite spring perch with a stainless-steel insert for seamless height adjustment, and an elastomer bump stop with integrated dust protection.
