KW V4 Clubsports are 3-Way independently adjustable coilovers that are a great choice for track and road driving.

KW V4 Clubsport coilovers are 3-way independently adjustable, giving you complete setup control. KW V4 Clubsports feature low-speed bump and rebound adjustment alongside independent high-speed bump adjustment.

3-Way independently adjustable dampers offer a huge performance advantage over 2-way dampers. The low-speed bump and rebound can be set to stiffer settings for increased mechanical grip and the independent high-speed bump setting can be set to a soft setting. This allows you to drive over bumps, kerbs and imperfections in tarmac without the car becoming unstable or deflected, which is ideal for the road and for the race track.

The high-speed bump setting makes driving on the road less uncomfortable than on the standard suspension.

KW V4 Clubsports feature aluminium monoball top mounts which feature far more camber adjustment compared to the standard Porsche top mounts.

Technical highlights of KW V4 Clubsport for Porsche 911 (997) GT3/RS & GT2/RS are:

  • 3-Way independently adjustable damping (6 clicks of low-speed bump, 16 clicks of low-speed rebound, 14 clicks of high-speed bump)
  • Fully ride-height adjustable
  • External reservoirs for superior thermal management
  • Supplied with KW monoball motorsport top mounts
  • Trapezoidal thread on shocks for longevity
  • Stainless steel "inox-line" construction for improved corrosion resistance
More information

Every single KW damper uses KW's twin-tube damper technology. Within each KW damper there are two tubes - the inner tube, which contains the piston and the majority of the damping fluid, and the outer tube which surrounds the inner tube and works as a reservoir for the damping fluid and helps to maintain consistent damper performance.

When encountering a bump or undulation the damper enters the compression phase. As the bump is driven over, the spring on the coilover is compressed. Kinetic energy is generated and accumulated in the spring.

During the compression stroke, the piston rod displaces the oil in the inner tube, which passes through the compression valve located at the bottom of the inner tube. The flow resistance at the compression valve generates the compression damping force. This flow resistance causes the speed of the compression stroke to slow down.

During this process, some of the oil beneath the compressing piston flows upwards through the check valve at low resistance, filling the inner tube behind the piston with oil, ensuring consistent performance.

During the rebound stroke, kinetic energy accumulated in the spring is transformed into heat energy internally as the damper rebounds. The speed at which this happens is controlled by the flow resistance of the rebound valve.

As the piston rebounds the oil above the piston in the inner tube flows through the holes in the rebound valve. The resistance offered by this valve controls the rebound velocity.

Whilst this is happening, oil stored in the outer tube flows back into the inner tube via the check valve.

The compression and rebound phases are complete and the high-quality KW damper helps keep the wheel in contact with the tarmac and under control at all times.

TVR-A explained

TVR-A stands for Twin Valve Rebound - Adjustable. The technology works at both at both high and low damper speeds. When a bump is encountered at low speed, such as during every day driving or commuting, the internal damper fluid flows at a low volume through an adjustable, conical low-speed bypass. This makes the damper far more supple during day to day use as the damper rebounds more slowly and less harshly than a standard damper.

TVCLH-A explained

TVCLH-A stands for Twin Valve Compression Low Highspeed - Adjustable. TVCLH-A features 6 clicks of low speed and 14 clicks of high speed compression or 'bump'. These clicks increase or decrease the cross sections of the internal valves within the damper to achieve more or less compression damping.

TVCLH-A equipped dampers contain blow off valves with large cross sections to allow the damper oil to flow quickly if a sudden compression or bump is encountered. These blow off valves enable you to set stiff low speed compression settings for optimum performance, without having to worry about the wheels being deflected or losing contact with the ground when driving over kerbs and bumps on the circuit.

Why choose coilovers?

Car manufacturers often elect to save money when building cars by using cheap and reliable springs and dampers instead of high-quality performance items.

This is where aftermarket coilovers come in. Aftermarket coilover manufacturers use far higher quality materials and more sophisticated technology in their products. The resulting products are of a much higher quality than the springs and dampers that are fitted to your car as standard.

Alongside higher quality materials, the technology used inside aftermarket dampers such as the valving and piston design is far more advanced. Most coilovers are adjustable, allowing you to fine-tune the bump and rebound characteristics of the damper. This gives you full control over the kinematics of your car.

The main advantage of coilovers is in the higher level of grip they create. The higher quality springs and dampers are effective at keeping the tyres in contact with the tarmac even over rough surface, ensuring the tyres are creating as much grip as possible. The tuneable damping settings allow you to reduce body roll; to eliminate nose-diving under heavy braking, and to reduce squat under acceleration.

Coilovers are fully ride-height adjustable. You can adjust the ride height to improve cornering by introducing rake angle, which improves turn-in and increases braking stability. Ride height adjustability allows for a corner-weighting setup to be done, and this greatly improves acceleration, braking and cornering.

Coilovers are a comprehensive suspension performance upgrade, not only in terms of technology and materials but also in terms of the far more in-depth setup possibilities they offer.
