Upgrade the handling, stance, and everyday driving experience of your 2000-2006 Audi TT or TT Roadster Quattro (8N) with the ST Suspensions ST X Coilover Kit, part number STS13210041. Developed for drivers who want sharper cornering without sacrificing street comfort, this application-specific suspension system combines sport-oriented performance with straightforward ride-height adjustment. The kit is engineered for the Audi TT Quattro 1.8T four-cylinder platform and is tuned to complement the vehicle’s dynamics for confident daily driving.
The ST X Coilover system provides a broad range of ride-height adjustment, helping you fine-tune wheel and tire fitment while improving the vehicle’s appearance and driving behavior. A friction-optimized polyamide composite spring perch with a stainless-steel insert supports smooth, long-lasting adjustment while helping prevent corrosion between the perch and strut. Galvanized steel damper housings add corrosion resistance, making the system suitable for continued street use.
ST Suspensions uses advanced damper construction developed with KW engineering expertise. Elastomer bump stops with integrated dust protection help shield the hardened chrome piston rods and seals from water and debris while providing progressive load control. A multi-layer pressure-resistant sealing package, monoblock guide system, and low-friction piston band support consistent operation and durability. Each damper is assembled by hand in Germany and tested on a shock dynamometer before packaging, helping verify proper damping performance.
Made in Germany, the ST Suspensions ST X Coilover Kit delivers a practical balance of comfort, adjustability, and sporty response. The kit includes a five-year limited warranty with unlimited mileage and is designed specifically for the listed Audi TT Quattro applications.
