^ that is correct but the tolerance on the BMW is much much tighter then the ford, jeep and chevy. Since, the diff is not under the car. You will need a case spreader. Won't be able to use a crowbar to pry out the diff. If not done correctly it will destroy a Ring and Pinion and Bearings. I have installed Eaton, ARB, Lincoln Welded, and Qualife LSD/Lockers.
