ST X height-adjustable coilover kit for the 2002-2006 Mini Cooper and Cooper S (R50 hatchback, R52 convertible). Ride height is set via a friction-optimized polyamide composite spring perch with a stainless-steel insert, with fixed KW-tuned damping specific to this application. Built by hand by KW in Fichtenberg, Germany, and shock-dyno tested before shipping. Galvanized zinc-coated steel struts with elastomer dust protection and a multi-layer sealing package deliver long-term corrosion resistance.
