For each vehicle class and for every operational use, KW offers the optimal adjusted suspension, from comfortable, to sporty or performance-oriented. This demanding objective can only be achieved with the innovative, patented KW technology with an individually adjustable rebound- and compression damping. For this reason, KW base the damping developments on double-pipe technology. With the 2-way pressure valve technology two, basically incompatible characteristics – dynamics & driving comfort – can be uniquely combined.
For KW coilovers Variant 3, it is also possible to adjust the basic setup of the bottom valve via the compression adjustment in twelve precise clicks. With the compression damping, the speed of the piston rod during immersion is controlled. It has a direct impact on the body movements and the steering behaviour.
When the compression valves are opened, the compression damping will be reduced and the vehicle immerses faster when steering. When the compression damping is incresed, the piston rod immerses slower and the vehicle acts more stable when steering. The steering behaviour gets more precise, the stronger the compression damping is adjusted.
Piston rod steering- and sealing kit
KW modular sealing system surpasses the usual OEM standards. It can be easily opened due to its aluminium bolting and therefore allows a later, custom-made adjustment of the valve technology or the deviation ratio

When a car deflects when driving, the oil which is lightly under pressure, will be displaced by the immersion of the piston rod. It flows into the outer tube through the bottom valve (compression valve) which controls the flow speed. During rebound, the oil flows from the outer tube back into the inner tube. In addition to the channels in the bottom valve, the oil also has to flow through the rebound valve located at the piston rod, to get into the piston housing.
The damper of a suspension kit converts the kinetic energy of the suspension spring into heat energy and passes it into the environment. When driving a curve, the KW coilover kit works in the curve inside of the vehicle in rebound and in the curve outside in compression damping.
The rebound damping directly affects the operating speed of the piston rod rebound springing and the expansion rate of the suspension spring. So it also determines how fast the suspension spring is expanded back in their original position. At the KW coilovers Variant 2 and 3, the driver can adjust the rebound via 16 precise clicks.
So the diameter of the rebound valves will be opened for a softer driving behaviour and closed for a tighter setup. With the adjustable rebound of the KW coilovers, the vehicle handling and comfort can be influenced.
At the KW coilovers Variant 3 it is also possible to adjust the basic setup of the bottom valve via the compression adjustment in twelve precise clicks. With the compression damping, the speed of the piston rod during immersion is controlled. It has a direct impact on the body movements and the steering behaviour.
When the compression valves are opened, the compression damping will be reduced and the vehicle immerses faster when steering. When the compression damping is incresed, the piston rod immerses slower and the vehicle acts more stable when steering. The steering behaviour gets more precise, the stronger the compression damping is adjusted.
