KW's height adjustable sleeve kit for the E9x M3 allows 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, height adjustable spring perches for the front and rear, shortened bump stops and new dust boots to protect the OE BMW shocks.
