KW Mercedes C Class W205 Convertible 4MATIC AWD Without EDC H.A.S.

Starting with high-strength springs made of multi-coated chrome-silicon steel, this KW Height Adjustable Spring (H.A.S.) kit is designed to give your 2017-2023 Mercedes-Benz C300 Convertible 4MATIC AWD a sportier stance and improved handling. Unlike traditional lowering springs that offer a fixed drop, the H.A.S. system lets you fine-tune the ride height on each corner with millimeter precision, even after installation. This means you can dial in the perfect look and feel for your car, whether you're aiming for a subtle drop or a more aggressive stance.

KW's engineers have developed specific spring rates that are tuned to work harmoniously with your C300's factory dampers, ensuring that your car's steering response and overall agility are enhanced without sacrificing the comfortable ride quality you expect. Crucially, this kit maintains the full functionality of your vehicle's factory electronic suspension systems and driver assistance features. You also get application-specific bump stops with dust protection, which help shield your factory suspension components from road grime and debris, contributing to their longevity.

This kit provides a continuous, adjustable ride height within a tested range, similar to a coilover setup but utilizing your original shock absorbers. The included height adjustment mechanisms and dust protection elements are set to achieve the maximum technically possible lowering, typically limited by the factory dampers. Comprehensive testing on the Nurburgring Nordschleife and at KW's 7-post Driving Dynamic Test Center ensures these springs deliver a sporty yet balanced driving experience.
