KW Coilover Kit V1 12+ BMW 3 Series F30 6-Cyl w/ EDC Bundle

KW is known for developing high-performance suspension systems, and their V1 INOX-LINE coilover kit is a great entry point into street performance. This kit is specifically tuned for a range of BMW vehicles, including models like the 335i, 340i, 435i, and 440i, offering a balanced and sporty feel that enhances driving pleasure. It allows for a maximum lowering within an approved range, ensuring your suspension functions correctly while giving your car a more aggressive stance.

What sets the V1 apart is its INOX-LINE stainless steel construction, which provides true permanent corrosion resistance. This means the coilover struts won't corrode even after years of use and adjustment, thanks to the dirt-resistant trapezoid thread and composite adjustment collars. KW engineers develop a specific damper setup and spring rate for each vehicle application, tested extensively on the Nürburgring Nordschleife and in their 7-post chassis dynamics test center. This vehicle-specific tuning results in reduced body roll and a more direct, sporty handling feel. The kit also includes elastomer bump stops with integrated dust protection to keep dirt and water away from the piston rod and seals, further contributing to durability and ride quality.

This kit comes with everything needed for installation, including the corrosion-resistant springs, bump stops, and dampers, all pre-configured by KW's engineers for an optimal balance of sportiness and practicality. The composite spring perches, made from wear-resistant polyamide with a stainless-steel insert, prevent oxidation and maximize strength. Each coilover strut is hand-built in Germany and individually serial numbered, then dyno-tested to ensure functionality and accuracy before shipping. This attention to detail and quality components is backed by a limited lifetime warranty with unlimited mileage.
