e36 M3 euro large case 210mm differential with custom 3 clutch lsd built by diffsonline. A bullet proof unit good up to 800-1000 horsepower. 4:10 ring & pinion plus REM® Ring & Pinion Polishing and 3 clutch 30/90 ramps. I will also include the euro rear sub-frame that bolts into the stock factory mounting points. This is my spare unit, only used once since built by diffsonline.
