KW Coilover Kit V1 BMW Z4 sDrive M40i (G29) / Toyota GR Supra (A90)

KW Suspensions is well-known for their performance suspension components, and their V1 INOX-LINE coilover kit is a great entry point into their street performance lineup. This kit is specifically developed for your 2019-2025 BMW Z4 sDrive M40i (G29) and 2020-2025 Toyota GR Supra (A90), offering a balanced and sporty feel tailored to each vehicle. It allows for a maximum lowering within an approved range, ensuring your suspension functions correctly while giving your car a more aggressive stance.

The V1 kit features INOX-LINE stainless steel struts for truly permanent corrosion resistance, meaning the threads won't seize up even after years of adjustment. The composite spring perches, made from a wear-resistant polyamide with a stainless steel insert, prevent oxidation and maximize strength. KW engineers develop a specific damper setup and spring rate for each application, tested extensively on the Nurburgring and in their 7-post chassis rig. This pre-configured setup provides an optimal balance of sportiness and practicality, reducing body roll for more direct and sporty handling without sacrificing too much comfort.

With this kit, you can easily adjust the ride height thanks to the dirt-resistant trapezoid thread and composite adjustment collar. Each damper is individually tested before leaving the factory in Germany, ensuring functionality and accuracy. This coilover system is designed for a direct fit, and the integrated dust protection system on the elastomer bump stops helps prevent dirt and water from reaching the piston rod and seals, contributing to long-lasting driving pleasure.
