KW Coilover Kit V3 BMW 4 series F33 Convertible 2WD w/ EDC

The KW V3 Coilover kit starts with a patented TVR-A (Twin Valve Rebound - Adjustable) technology. This system allows oil to flow past an adjustable, conical low-speed bypass during slow damper speeds. At higher speeds, the main rebound stage valve opens for maximum fluid displacement, giving you precise control over your car's response. This kit is designed for a range of BMW 4 Series models, including the 428i, 430i, 435i, and 440i, whether you have a Convertible or Gran Coupe, as long as it's 2WD with electronic dampers.

This is a well-built suspension system that brings motorsports technology to the street. The V3 kit features TVC-A (Twin Valve Compression - Adjustable) technology, allowing you to fine-tune low-speed compression damping. This means you can independently adjust compression and rebound to match your driving style or vehicle changes, like different tires or added weight. The composite spring perch, made from wear-resistant polyamide with a stainless-steel insert, prevents oxidation and maximizes strength. Plus, the Inox-Line Stainless Steel construction means these struts are permanently corrosion-resistant, with an unlimited lifespan, even when you're adjusting the ride height. Each damper is hand-built in Germany, dyno-tested, and given a unique serial number to ensure accuracy and performance.

The kit includes elastomer bump stops with integrated dust protection to keep dirt and water away from the piston rod and seals, while also acting as dynamic load limiters. This attention to detail helps maintain ride quality and durability. With application-specific spring and damper tuning, this coilover kit offers improved street performance and significantly reduces pitching and rolling during load changes, leading to shorter braking distances and a more confident driving experience.
