Why Choose the KW V4 Clubsport inc Top Mounts

The V4 Clubsport is the definitive choice for E9X M3 owners seeking ultimate chassis performance. Unlike two-way systems, the V4 separates low-speed and high-speed compression damping, giving you the ability to fine-tune how the car reacts to weight transfer, kerbs, bumps, and high-speed cornering loads. Combined with the supplied adjustable uniball top mounts, the V4 provides exceptional steering precision and camber stability.

This system is engineered to perform consistently under extreme conditions — whether during long stints, repeated hard braking, or sustained cornering at high temperature. For drivers who want the closest experience to a KW motorsport suspension while retaining road usability, the V4 Clubsport is the benchmark.

Installing / Notes

• Professional installation, corner balancing, and a track-aligned geo setup are strongly recommended.

• Uniball top mounts require periodic maintenance as part of motorsport usage.

• Adjustment points are accessible for quick changes at the circuit.

• Clearance should be checked when running aggressive wheel/tyre setups or lower ride heights.
