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's Variant 3 suspension for the E9x M3 offers a comfortable ride quality with progressive rate springs, a wide range of height adjustment, and adjustable compression and rebound damping. The damper housings are constructed from stainless steel for corrosion resistance and high strength. An EDC compatible model is available which includes a module to defeat the M3's built-in electronic damping control, and prevent any check engine light when removing the system from the car.
