The ST X coilover kit is an application-specific, height-adjustable suspension built by hand by KW in Germany for daily-driven Audi A3/TT and Volkswagen Golf, GTI and Jetta platforms. Galvanized zinc-coated steel strut housings and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting ride-height adjustment, while the dampers and spring rates are tuned in Germany for each vehicle. A multi-layer sealing package and elastomer bump stop with integrated dust protection shield the hardened chrome piston rod from dirt and water. Each damper is shock-dyno tested before it leaves the factory and is backed by a 5-year unlimited-mileage limited warranty.
