The ST X coilover kit is a height-adjustable suspension system for the BMW E39 5-Series sedan (525i, 528i, 530i, 540i without factory air suspension), engineered by KW in Germany. It uses galvanized zinc-coated steel struts with a friction-optimized polyamide composite spring perch and stainless-steel insert for corrosion-free ride-height adjustment, plus a hardened chrome piston rod, dust protection system, and monoblock guide for long-lasting daily performance. Each damper is application-specific, hand-built and shock-dyno tested in Fichtenberg, Germany.
