KW V4 Racing Coilover Kit for Trackday Performance with Semi-Slick Tires

The KW V4 Racing coilover system is derived from proven GT4 customer motorsport technology and tailored for uncompromising track performance. Designed for non-homologated racecars and purpose-built track tools, this kit delivers precise damping control and vehicle-specific tuning for high-performance use on closed circuits. Unlike the KW V3 Clubsport, the V4 Racing version does not include road certification, emphasizing its pure motorsport orientation.
