KW Coilover Kit V2 BMW 4 series F33 428i Convertible RWD without EDC

This KW V2 INOX-LINE coilover kit includes front and rear struts with integrated springs, composite spring perches, and bump stops. It's designed for BMW 4 Series models like the 428i, 430i, 435i, and 440i, specifically for rear-wheel-drive vehicles without electronic damper control. This kit allows you to adjust both the ride height and the rebound damping, giving you a direct influence on your car's handling and comfort.

The V2 kit uses KW's TVR-A (Twin Valve Rebound - Adjustable) technology. This system lets you fine-tune the rebound damping with 16 precise clicks. You can choose to make the ride firmer for better body control during spirited driving, or softer for improved comfort on longer trips, all without affecting the compression damping that KW engineers have already set for your specific vehicle. The struts are built with Inox-Line stainless steel for excellent corrosion resistance, and the composite spring perches prevent oxidation while maintaining strength. This means you can easily adjust the ride height even after years of use.

KW develops these kits with vehicle-specific damper settings, tested extensively on the Nurburgring and in their own driving dynamics test center. The kit also includes elastomer bump stops with an integrated dust protection system to keep dirt and water away from the piston rod and seals. You can achieve a lowered stance within an approved range that ensures proper suspension function and adequate travel.
