The KW V1 INOX-LINE coilover kit is our entry point into our street performance lineup. The high-quality INOX-LINE stainless steel coilover struts, corrosion resistant springs, bumps stops and dampers that are optimally tuned by our engineers the result is a balanced and sporty feel specific to each vehicle application designed for long lasting driving pleasure. With KW V1 coilovers you can achieve maximum lowering within an approved lowering range that ensures a proper functioning suspension and adequate travel after your car is lowered. Even after years of use you can easily adjust the ride height thanks to the dirt resistant trapezoid thread and composite adjustment collar. KW INOX-LINE coilover rewards the sporty driver with its harmonious pre-configured setup. For each vehicle our engineers develop a specific damper setup and spring rate to increase the driving pleasure with an optimal balance of sportiness and practicality. As with all KW coilovers, the engineers at KW develop the vehicle-specific KW damper tuning and spring rates with comprehensive testing on the Nurburgring Nordschleife and in the KW 7-post chassis dynamics test center. Unlike a mass produced, generic coilover kit, KW coilovers are developed specifically for your vehicle. As a manufacturer, KW uses only its own resources, high quality components and the damper technology that was all developed in-house. With the KW V1 coilovers, body roll will be reduced during compression giving you the benefit of a more genuine and direct sporty handling while driving.
