ST X-Height Adjustable Coilover Kit Mercedes C-Class (W203 / W203K) RWD Sedan / Wagon

If you're looking to give your Mercedes C-Class (W203/W203K) or CLK (W209) a sportier stance and more responsive feel, the ST X Coilover kit is a solid option. This kit is designed to hug curves while still offering a comfortable ride for daily driving, letting you dial in both the look and the handling of your car. It's built for drivers who want a straightforward performance upgrade without overcomplicating things.

What sets these coilovers apart is the attention to detail in their construction. The galvanized steel struts are built to resist corrosion, and the spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This unique combination prevents corrosion between the strut and perch, ensuring that you can adjust your ride height smoothly for years to come. ST Suspensions also incorporates an elastomer bump stop with an integrated dust protection system, keeping dirt and water away from the piston rod and seals, which helps maintain the damper's performance and longevity. The dampers themselves are built by KW in Germany, known for their world-class engineering, and each unit is tested on a dyno before it ships to ensure it meets proper force specifications.

This kit is application-specific, meaning it's tuned by ST's engineers in Germany with damper and spring rates tailored to match your specific Mercedes model. The seamless ride height adjustment, thanks to the composite spring perch and a unique trapezoidal thread pitch, makes it easy to achieve your desired look. You get a well-built suspension system that's made in Germany and backed by a 5-year limited warranty with unlimited mileage.
