KW Mercedes C Class W205 Convertible C43 AMG 4MATIC AWD With EDC H.A.S.

If you're looking to give your 2017-2023 Mercedes-Benz C300 a sportier stance and improved handling, KW's Height Adjustable Spring (H.A.S.) kit is a smart way to go. Unlike standard lowering springs that lock you into one height, this system lets you dial in the ride height with millimeter precision, even after installation. This means you can fine-tune the look and feel of your C300 to your exact preference.

These aren't just springs; they're engineered to work seamlessly with your car's original electronic suspension system, so all your factory comfort and driver assistance features remain fully operational. KW uses high-strength chrome-silicon steel for their springs, with rates carefully matched to your specific OE dampers and vehicle weight. This ensures a sporty yet comfortable ride that doesn't compromise the dynamics of your performance-oriented Mercedes. The kit also includes application-specific bump stops and dust protection to help keep your factory shocks protected from road debris.

With the KW H.A.S. kit, you get the benefits of adjustable ride height, similar to a full coilover setup, without sacrificing the integration with your car's advanced electronic damping. KW develops these kits with extensive testing, including time on the Nurburgring and at their own 7-post driving dynamics test center, to ensure they perform as expected.
