KW Coilover Kit V1 BMW Z4 (E85) Coupe Roadster

If you're looking to give your 2003-2008 BMW Z4 a more athletic stance and improved handling, the KW V1 INOX-LINE coilover kit is a solid choice. This kit is designed to lower your Z4 within an approved range, ensuring your suspension still functions correctly with adequate travel. KW's engineers develop a specific damper setup and spring rate for each vehicle application, aiming for a balanced feel that's sporty yet practical for daily driving. You'll notice reduced body roll during cornering, which translates to more direct and responsive steering feel.

What sets these coilovers apart is their construction and tuning. The struts are made from INOX-LINE stainless steel, which means they're truly resistant to corrosion, even when you're adjusting the ride height using the dirt-resistant trapezoid threads and composite adjustment collars. This makes adjustments easy, even after years of use. KW tests every damper extensively on the Nürburgring Nordschleife and in their 7-post chassis dynamics test center to ensure the preset damping and vehicle-specific spring rates work harmoniously. This means you get a well-tuned suspension right out of the box, without needing to guess at settings.

This kit includes everything needed for installation, featuring elastomer bump stops with integrated dust protection to keep dirt and water away from the piston rod and seals. The composite spring perches are made from a wear-resistant, friction-optimized polyamide that prevents oxidation. Each coilover is hand-built in Germany and given a unique serial number, with every damper dyno-tested before shipping. KW also backs these coilovers with a limited lifetime warranty for unlimited mileage.
