KW Suspensions E9X M3 Height Adjustable Spring Kit
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 sleeve kit for the E9x M3 allows a large range of height adjustment while retaining the factory electronic damping control. The factory spring perches are removed from the front dampers, and KW's own threaded height-adjustable perches are installed. The sleeve kit allows for .5"; to 1.2"; of lowering in front, and .2";-.5"; of lowering in the rear. The kit includes progressive rate lowering springs for each corner of the car, height adjustable spring perches for the front and rear, strengthened and shortened bump stops and KW shock sleeves to protect the OE BMW dampers.
