KW Coilover Kit V1 04-10 BMW 6 Series E63 / E64 (663C) Coupe / Convertible

This KW V1 INOX-LINE coilover kit includes the front and rear coilover struts, corrosion-resistant springs, bump stops with integrated dust protection, and composite spring perches. It's designed to give your 2006-2010 BMW 650i a balanced and sporty feel while allowing you to adjust the ride height. KW engineers develop a specific damper setup and spring rate for each vehicle application, drawing on extensive testing at places like the Nürburgring Nordschleife and their own 7-post chassis dynamics test center. This means you get a harmonious, pre-configured setup that balances sportiness with practicality for everyday driving.

The INOX-LINE stainless steel construction offers true permanent corrosion resistance, meaning the struts won't corrode even after you've adjusted the ride height using the dirt-resistant trapezoid thread and composite adjustment collars. These composite spring perches are made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation while maintaining strength. The elastomer bump stops work with the integrated dust protection system to keep water and dirt away from the piston rod and seals, ensuring long-term durability and ride quality. Each damper is dyno tested before leaving KW's headquarters in Fichtenberg, Germany, ensuring functionality and accuracy.

With this kit, you can achieve maximum lowering within an approved range, ensuring proper suspension function and adequate travel. Body roll is reduced during compression, leading to more direct and sporty handling. This is KW's entry-level street performance coilover system, offering a solid option for those looking to lower their vehicle and improve its driving dynamics.
