I just rebuilt my diff with new bearings seals and M factory lsd unit. With the OEM shims the backlash is way off so I need new shims to set it correctly. Unfortunately it seems bmw no longer makes them and I have only found racing diffs and diffs online that carry shims but they want a ton of money for some simple shims. So, I am hopping someone here might have a set they dont need anymore....
