The KW V1 Inox-Line coilover kit is the definitive entry point into street performance suspension, providing a factory-set damping profile that strikes an optimal balance between sporty handling and daily driving comfort. Engineered specifically for the BMW F30 and F32 chassis, these coilovers utilize vehicle-specific spring rates and damping curves to reduce body roll and improve steering response without sacrificing ride quality. Every kit is hand-built in Fichtenberg, Germany, and subjected to rigorous dyno testing to ensure performance accuracy.

Construction features KW's proprietary Inox-Line stainless steel technology, which provides permanent corrosion resistance and ensures that the height adjustment remains functional even after years of exposure to the elements. The height is adjusted via a dirt-resistant trapezoid thread and a friction-optimized polyamide composite collar with a stainless steel insert, preventing the oxidation and seizing common with inferior galvanized kits.
