The KW V4 Clubsport Coilover Kit with adjustable top mounts represents the highest level of track-focused suspension engineering available for the BMW E9X M3. Developed directly from KW’s motorsport programmes, the V4 Clubsport delivers full three-way damping adjustment — independent rebound, low-speed compression, and high-speed compression — giving drivers the ability to dial in their chassis dynamics with exceptional precision.

Designed for serious track-day enthusiasts and competitive drivers, the V4 Clubsport offers unrivalled control, consistency under high heat, and the direct steering feedback the S65 chassis deserves. This is KW’s ultimate dual-purpose fast-road and motorsport suspension system for the E90/E92/E93 M3.

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.
