KW Coilover Kit V3 BMW 4 series F33 428i Convertible RWD without EDC

The KW V3 Coilover kit uses a patented TVR-A rebound and TVC-A compression valve system, allowing for independent adjustment of both low-speed and high-speed damping forces. This advanced technology, developed from motorsports, significantly reduces body roll and pitching during acceleration, braking, and cornering, leading to shorter braking distances and improved stability. The kit is designed to fit a range of BMW 4 Series models, including the F33 convertible and F36 Gran Coupe variants like the 428i, 430i, 435i, and 440i, provided they are rear-wheel drive and do not have factory electronic dampers.

Each damper in the V3 kit is built with Inox-Line stainless steel for permanent corrosion resistance, ensuring a long lifespan even with frequent adjustments. The composite spring perches are made from a wear-resistant, friction-optimized polyamide that prevents oxidation, while an integrated stainless-steel insert provides maximum strength. The kit also features elastomer bump stops with an integrated dust protection system to keep dirt and water away from the piston rod and seals, maintaining ride quality and durability. Every KW V3 coilover kit is hand-built in Germany, individually serialized, and dyno-tested before shipping to ensure accuracy and performance.

With the ability to fine-tune both compression and rebound damping independently, you can customize the suspension setup to match your driving style, tire choice, or any vehicle modifications. This makes the KW V3 coilover kit a powerful tool for performance-oriented drivers looking to optimize their vehicle's handling and grip for confident driving, whether on the street or at the track.
