KW V4 Clubsport Coilovers - BMW F87 M2/M2 Competition

KW Clubsport V4s are 3-way adjustable coilovers that are supplied with fully adjustable camber plates, which makes them suitable for intensive road use, track day applications and cars with slick tyres.

The key features of the KW Clubsport V4 Coilovers for BMW F87 M2/M2 Competition are:

• 3-Way independently adjustable (6 clicks of low speed bump, 14 clicks of high speed bump, 16 clicks of rebound)

• Fully height-adjustable

• Supplied with camber adjustable camber plates

• Stainless Steel "inox line" construction for improved corrosion resistance

• Trapezoidal height adjustment thread ensures consistent performance across the lifespan of the product

• Tested at the Nürburgring

• Ideal for track cars using slick tyres 

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.
