The ST X coilover kit delivers height-adjustable suspension for the everyday driver who wants sharper handling without sacrificing ride comfort. Each kit is application-specific, hand-built by KW in Fichtenberg, Germany, and uses galvanized zinc-coated steel struts with a friction-optimized polyamide composite spring perch and stainless-steel insert for corrosion-resistant, long-lasting ride-height adjustment. Dampers and spring rates are tuned by ST's vehicle dynamics engineering and dyno-tested before boxing.
