KW Coilover Variant 3 Inox with adjustable rebound and compression damping
4WD; without electronic dampers
Maximum allowed front axle weight: (KG) 1001-1020
Maximum allowed rear axle weight: (KG) -1120
Power: kW 235-250
Approved front lowering: (mm) 30-55
Approved rear lowering: (mm) 30-55
Height adjustable front and rear axles (front axle threaded strut housings, rear axle adjustable springs + dampers)
When using original tyres, wheel offset spacers may be required.
For cars which have electronic dampers, make sure they are shut down. Specific electric damper shut-downs are available from KW. Please check our accessories list.
Dampers are adjusted by easily operating adjustment wheels. Rebound is only adjustable if the top of the piston rod is accessible. This will depend on the vehicle construction.

KW Coilovers Variant 3
Cutting-edge motor sports technology for more performance on the road. With compression and rebound stage damping, that can be set separately and independently of each other, the damper setup can be customized to your own driving preferences or vehicle changes such as weight, tire characteristics or altered vehicle rigidity. True performance optimization is only possible with this unique, patented system. For example, this allows the compression damping force to be increased and get more grip from the tires, to improve cornering behavior and reduce squat without simultaneously altering the rebound stage damping which is optimally matched to the spring rate – a scenario which results in reduced grip and the associated loss of performance.
Setup – factory-set pre-configured damper setup with separately adjustable compression and rebound stage damping
The KW coilover kit Variant 3 "inox-line" is the ideal accessory for performance-oriented drivers and tuning enthusiasts who place a high demand on sportiness at their vehicles. The dampers with their “TVR-A” and “TVC-A” technology that are separately adjustable in rebound and compression damping allow an extensive damper setup. So it is easy to directly influence the steering behavior, directional stability, tire grip and handling characteristics for a safe controllability at the limit.TVR-A rebound stage damping (Twin Valve Rebound – Adjustable): The two-step, patented “TVR-A” technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed in the safety-relevant range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control. TVC-A compression stage damping (Twin Valve Compression – Adjustable): With 12 precise clicks the adjustable compression stage valve (“TVC-A”-technology) can increase or decrease the cross section in the low-speed valve to achieve either more or less compression stage damping. At the same time, in the case of sudden high piston speeds, the spring pre-tensioned needle valve and the spring pre-tensioned main valve open to their maximum valve cross section, to avoid with its blow-off characteristics undesired progressive force increase in the high-speed range. This allows a better bracing of the vehicle body and at the same time at high wheel acceleration offering more comfort than with conventional valve technology. The compression stage damper setting is always supplied in combination with a separate rebound stage setting, as only an independent 2-way damper setting allows a true performance optimization.
The KW Variant 3 allows a maximum or individual lowering within the tested adjustment range. Due to the dirt-resistant trapezoidal thread and the polyamide threaded ring, the continuously lowering can be varied quickly and easily, even after the years.
The benchmark for coilovers
As with all KW coilovers, the engineers at KW develop in extensive test cycles on the Nürburgring Nordschleife and in our test center on the KW 7-post rig the vehicle-specific KW damper setup estimated by car enthusiasts worldwide. So you will experience your car even more directly and dynamically with a KW coilover kit.
After all, you do not buy just any coilover kit, but a KW coilover kit that has been specially developed and adapted for your vehicle type. KW as manufacturer exclusively uses own resources, high-quality components and the same damper technology as high-volume manufacturers. With the KW coilover suspension Variant 3 “inox-line”, the roll and pitch movements of the vehicle body are reduced during compression, so you benefit from an unadulterated directness and a sportier handling while driving.
Our experiences for your driving pleasure
For more than 20 years, we as manufacturer have been the market leader and innovator of individual suspension solutions for the street and racing applications. No matter where in the world, sporty drivers, automobile manufacturers and refiners rely on our KW coilovers “Made in Germany”.
Every KW coilover kit undergoes extensive stress tests during production and is developed and manufactured directly in our company headquarters in Fichtenberg in order to meet the high standards of our KW quality management. So for us as a German manufacturer, it is important that we guarantee a several-year warranty on our KW coilover kits, which exceed the original equipment manufacturer quality, as well as suspension solutions which include more than 4,600 applications.
