KW V4 Clubsport - 3 Way BMW M3 E9X w/o EDC

The KW V4 Clubsport 3-Way coilover system is the most advanced road-legal suspension solution available for the BMW E9X M3 below full motorsport competition dampers. Developed through extensive Nordschleife track testing and 7-post rig validation, this system is engineered to extract maximum performance from the chassis while allowing precise tuning for vehicle weight, wheel loads, tire selection, and chassis stiffness.

Derived directly from KW’s Competition 3-Way motorsport technology, the V4 Clubsport allows independent adjustment of rebound, low-speed compression, and high-speed compression, giving experienced drivers full control over grip, stability, and handling balance across changing track conditions.

This version is designed specifically for BMW M3 E9X models without factory EDC, offering a true plug-and-play installation with no electronic workarounds required.

Key Features

• 3-way independently adjustable damping (rebound, low-speed compression, high-speed compression)

• KW patented TVR-A (Twin Valve Rebound – Adjustable) technology

• KW patented TVCLH-A (Twin Valve Compression Low / High – Adjustable) reservoir system

• INOX-LINE stainless steel construction for permanent corrosion resistance

• Continuous ride height adjustment

• Motorsport-grade components with OEM-level durability

• Optional aluminum spherical bearing top mounts for increased feedback and camber tuning

Damping Adjustment

• Rebound: 16 precise clicks

• Low-Speed Compression: 6 clicks (purple adjuster)

• High-Speed Compression: 14 precise clicks (gold adjuster on reservoir)

This configuration allows independent control of chassis support, weight transfer, and tire contact at both low and high damper speeds.

Lowering Range

• Front: 0.4" – 1.5" (10 – 40 mm)

• Rear: 0.2" – 1.4" (5 – 35 mm)

Spring Rates

• Front: 630 lb/in

• Rear: 685 lb/in

Construction & Finish

• Material: Stainless Steel

• Finish: KW INOX-LINE

• Corrosion Resistance: Permanent (ISO tested)

Engineering & Development

The V4 Clubsport benefits directly from KW’s championship-winning motorsport experience, including multiple overall victories at the ADAC Zurich 24h Nürburgring. Each damper is hand-built, dyno-tested, and individually serialized at KW headquarters in Fichtenberg, Germany to ensure precision, consistency, and long-term reliability.

Fitment Notes

• Designed for BMW M3 E90 / E92 / E93 (non-EDC)

• Professional installation and alignment strongly recommended

• Intended for experienced drivers and advanced suspension tuning
