KW Coilover Kit V1 BMW 4 series F33 428i Convertible RWD with EDC (includes EDC cancellation)

The KW V1 INOX-LINE coilover kit starts with high-quality INOX-LINE stainless steel struts, which are truly permanent corrosion resistant. This means that even after years of use, adjusting the ride height remains easy thanks to the dirt-resistant trapezoid thread and composite adjustment collar. This kit is designed for a range of BMW 4 Series models, including the F33 Convertible and F36 Gran Coupe, offering a balanced and sporty feel specific to each application for long-lasting driving pleasure.

KW engineers develop a specific damper setup and spring rate for each vehicle, balancing sportiness and practicality. This V1 kit is pre-configured, taking the guesswork out of setup. The elastomer bump stops include an integrated dust protection system, preventing water and dirt from reaching the piston rod and seals, while also acting as dynamic load limiters. The composite spring perches are made from wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation and maximizing strength. Each damper is dyno tested before release to ensure functionality and accuracy.

This kit includes EDC cancellation, allowing you to retain electronic damping control functionality. The seamless ride height adjustment, combined with the corrosion resistance of the Inox-line stainless steel and composite perches, lets you dial in your preferred look. Every KW coilover is hand-built with a unique serial number at their headquarters in Fichtenberg, Germany.
