Patented KW Valve Technology

Rebound adjustment

Independent adjustable rebound damping

Adjustment

16 Clicks - Best perfomance and easy adjustment KW Variant 2 and KW Street Comfort coilover kits provide 16 clicks of rebound adjustment.

Rebound adjustments can be made to reflect more dynamic driving characteristics or complement a change in tire selection, such as: different set of tires or winter tires.

The Variant 2 coilover provides the user more then just the height adjustability of a coilover it. The adjustable rebound feature allows the user to dial in a more sportier tighter handling characteristic or a more compliant comfortable setting suitable

Oil flow during "hard" rebound stroke

Bypass orifice with closed adjuster position. Digressive damping characteristic and the maximum achievable rebound damping. Damping is determined by the setup specific preload of the valve spring at the piston.

The result:
A firm but not a hard rebound stroke adjustment avoids rolling- and pitching motions.

Oil flow during "soft" rebound stroke

Bypass orifice with open adjuster position. Progressive damping characteristic and the minimum possible rebound damping is achieved. The bypass oil volume (black arrows) is not available anymore for the spring preloaded valve at the piston and the damping

The result:
A lower rebound damping increases the driving comfort.

Compression adjustment

Individually adjustable compression damping

12-way adjustable compression damping with a denounced click feature The KW Variant 3 and KW Clubsport coilovers are the ideal system for performance orientated driving enthusiasts who value an a wide range of dampening adjustment for their vehicles.

The adjustable independent rebound and compression damping provides an extensive range of damper tuning. This provides the enthusiast to directly effect the turn-in characteristics, tracking stability, trip grip and handling at the vehicle's limits.

The patented KW valve technology for independent rebound and compression damping allows the user to customize their KW damper setup.

Oil flow during closed compression damping in the bottom valve

Figure 2:
Position of the bypass valve with increasing piston rod velocity

During low piston rod velocity (black arrows), oil is fl owing over the bypass valve

The high speed compression damping (white arrows) is generated by the spring preloaded sleeve. The closed compression valve generates a progressive characteristic low-speed compression damping graph

The result:
A firmer compression stroke adjustment prevents vehicle from rolling during cornering

Oil flow during opened compression damping in the bottom valve

Figure 2:
Position of the bypass valve with increasing piston rod velocity

During slower piston rod velocities (black arrows), oil is fl owing over the bypass valve

The high speed compression damping (white arrows) is generated by the spring preloaded sleeve. The opened bypass valve produces a digressive characteristic compression damping graph in Low-Speed ranges
