KW Suspensions GmbH was founded in 1992 in Murrhardt Germany and has grown to become a leading suspension tuner for European and Japanese cars. KW suspension is developed thoroughly by KW's engineers to have an extremely long service life and create a balance between great handling and a comfortable ride quality. KW has equipped winning race teams for over a decade, and is a supplier to AMG as well as BMW in the M3 GTS. KW's facility is one of only 15 facilities worldwide to be equipped with a 7 post suspension test rig, giving regular M3 enthusiasts access to Formula 1 technology.
KW Variant 4 Coilovers are a combination of our innovative, race-proven technology, as well as decades of experience tuning high-end sports cars, super sedans, and exotics such as the Audi R8, Audi RS6, BMW M3/M4, Lamborghini Aventador LP 750-4 SV, Dodge Charger SRT Hellcat, Mercedes AMG GT and more. In addition to the individually adjustable ride height, the KW Variant 4 Coilover kit allows an independent adjustment of the rebound dampening as well as the low-speed and high-speed compression dampening. Each KW Variant 4 Coilover kit is delivered with a vehicle-specific comfort setting, and with the integrated adjustment controls, the dampening characteristics can be set quickly and intuitively transformed into an optimized performance setup.
The 3-way adjustable high-performance dampers in the KW Variant 4 Coilover kits feature independent adjustment of the rebound dampening utilizing patented TVR-A technology, as well as the low speed and high-speed compression dampening utilizing TVCLH-A technology. The KW Variant 4 Coilovers are based upon successful race technology utilized by multiple overall winners of the ADAC Zurich 24h Nürburgring race.
