ST XA coilover kit for the 2020-2024 BMW M240i xDrive (G42) and M340i xDrive (G20). Built by KW in Fichtenberg, Germany, the XA combines threaded ride-height adjustment with 16-click rebound damping so you can dial in stance and driving character independently. Galvanized zinc-coated steel struts resist corrosion; the spring perch is friction-optimized polyamide composite with a stainless-steel insert. Every damper is shock-dyno tested before boxing. Carries a 5-year limited unlimited-mileage warranty.
