The ST X is a ride-height-adjustable coilover kit for the 2015-2022 Mercedes-Benz C300 (W205), engineered and hand-built by KW in Germany. Galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting height adjustability, while each damper is dyno-tested and tuned specifically for this application. An elastomer bump stop with integrated dust protection shields the chrome piston rod and seals from dirt and water.
