KW Coilover Kit V3 BMW 4 Series Coupe M440i xDrive w/Electronic Dampers

If you're looking to significantly improve the handling and performance of your 2021-2025 BMW 430i xDrive, this KW V3 Coilover Kit is a serious upgrade. Developed with technology from motorsports, this kit brings a noticeable increase in safety reserves for everyday driving. It works by reducing body roll and pitching during acceleration, braking, and cornering, which also helps shorten braking distances. You'll feel more connected to the road, with better feedback and support, making driving more confident and safer.

What sets the KW V3 apart is its ability to let you fine-tune the suspension to your exact preferences. It features patented TVR-A and TVC-A valve technology, allowing you to adjust the rebound and compression damping independently. This means you can dial in more grip for better cornering or reduce squat during acceleration without negatively affecting the rebound, which is crucial for maintaining performance. The kit includes application-specific springs and dampers, hand-built in Germany with Inox-Line stainless steel struts for permanent corrosion resistance. The composite spring perches are designed to be wear-resistant and friction-optimized, preventing oxidation.

This kit is built for performance-oriented drivers who want to optimize their vehicle's dynamics. The extensive adjustment range allows you to directly influence steering behavior, directional stability, and overall grip. Each damper is individually tested and set to KW's recommended settings before leaving the factory, ensuring accuracy and performance right out of the box. For installation, refer to the manufacturer's instructions, as this is a complex suspension component that requires proper setup.
