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.
