KW V3 Coilovers - BMW F22 M235i/M240i

Increase grip when cornering, braking and accelerating by installing a set of KW V3s to your BMW M235i/M240i.

The original springs and dampers on the M235/M240i are not entirely suitable for performance driving. The springs and dampers are budget items and overall grip and handling performance is restricted by them.

This is where the KW V3 coilovers come in. Compared to the original BMW springs and dampers, KW V3s feature higher quality springs, dampers and internal valving. As a result, KW V3s generate far more grip when cornering, braking and accelerating. 

KW V3s are 2-way independently adjustable (bump and rebound) which allows you to fine tune the characteristics of your dampers depending on whether you are using them on road or track, or for any other application.

KW V3 coilovers are also fully ride-height adjustable. This allows you to set the ride height to whatever you want, and allow your BMW to be corner weighted for even greater performance.

The key features of the KW V3 coilovers for the BMW M235i/M240i 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

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.
