KW V3 Coilovers - BMW E90/E92 M3

KW V3s are 2-Way adjustable coilovers that are compatible with OEM top mounts, making them a good choice for fast road and track day usage.

The key features of KW V3 Coilovers for BMW E90/E92 M3 are:

• 2-Way adjustable (12 clicks compression, 16 clicks rebound)

• Fully height adjustable

• Stainless steel "inox-line" construction for improved corrosion resistance

• Trapezoidal height adjustment threads to ensure consistent performance over the product's lifespan

• Patented Twin Valve Compression and Twin Valve Rebound technology for superior performance

• High quality racing springs

• Suitable for daily driving as well as performance driving

• Tested at the Nürburgring in Germany

PLEASE NOTE - vehicles fitted with BMW Electronic Damper Control (EDC) will require a delete kit to prevent error codes from occurring.

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.

TVC-A explained

TVC-A stands for Twin Valve Compression - Adjustable. This adjustment controls the cross-section of the low-speed damper valve to allow for more or less compression damping. When a large bump is encountered at high speed, both the needle valve and main valve openly completely to allow for efficient and consistent damper performance. The adjustable compression damping gives you superior vehicle support and control whilst also offering improved comfort versus OEM dampers.
