The struts in the Ohlins BMS Mi30 kit for the E46 M3 were designed to work with the OEM top mount. When converting to aftermarket camber plates, the "stack height" of the camber plate is much thinner than the OEM mount. This strut spacer kit moves the strut up to accommodate for the thinner stack height of the camber plates. This also help raise the spring perch up to give proper tire clearance on wider wheel/tire packages. We have found that in most cases an 18" x 9.5" et 35 wheel with a 275/35/18 tire will clear the perch/spring without the need to use wheel spacers.
This kit has been revised to come with the "Risers" only to space the clamp down.
Installation Notes:
Please see the picture where the gap in the spindle clamp should line up with the point on the tab that is tack welded to the side of the strut.
