The KW Variant 4 coilover kit is the most advanced suspension currently available for the G9X M5 platform. Designed using technology derived from professional motorsport, the V4 system delivers maximum performance adjustability while maintaining everyday usability. The triple adjustable damper design allows independent tuning of low-speed compression, high-speed compression and low-speed rebound, giving drivers the ability to fine tune handling and comfort to their exact preferences.

Each kit is engineered specifically for the G90 and G99 chassis, providing a precise driving experience whether on the street or at the track. As with all premium KW suspension systems, the V4 is built using stainless steel coilover bodies and is rigorously tested on KW’s 7-post rig and at the Nürburgring Nordschleife.
