KW Coilover Kit V2 BMW 4 Series F33 (435i) Convertible/xDrive (AWD) w/ EDC

If you're looking to give your 2017-2020 BMW 440i xDrive a more dynamic and direct driving feel, the KW V2 INOX-LINE coilover kit is a solid choice. These aren't just about lowering your car; they offer a significant upgrade in suspension performance with adjustable rebound damping. The kit includes stainless steel coilover struts and corrosion-resistant components designed for long-term durability, meaning they're built to handle years of use and easy height adjustments thanks to their dirt-resistant trapezoid threads and composite collars.

What really sets the V2 kit apart is its TVR-A (Twin Valve Rebound - Adjustable) technology. This system allows you to fine-tune the rebound damping with 16 precise clicks. You can adjust the suspension to be firmer for more body control during spirited driving, or softer for improved ride comfort, all without affecting the compression damping that KW's engineers have already precisely tuned for your specific vehicle. This adjustability gives you a direct influence on how your car handles and feels on the road, whether you're navigating the Nurburgring or just your daily commute.

KW develops these damper settings through extensive testing, including on the Nurburgring Nordschleife and their own 7-post driving dynamics test center, ensuring they're specifically calibrated for your BMW 4 Series. The kit also includes elastomer bump stops with integrated dust protection to keep dirt and water away from the piston rod and seals, further enhancing durability. You can achieve maximum lowering within an approved range that ensures proper suspension function and adequate travel.
