There is a reasonable amount of adjustment range in the factory eccentric suspension bolts, for a variety of ride heights and possible alignment settings. Using the BMW upgrade Fall-Line Motorsports E9X M3 Rear Camber Shim Kit, however, with its rigid shims, will provide an increased amount of adjustability beyond what is provided by the factory installed parts. You can find this BMW upgrade at Olsen Motorsports.
