Just did a TON of research on this. Mine is a 550i 6M. The M5 diff will not bolt on and neither will the 3.38 stock diff form an auto. Your options really are to go with a custom LSD (if you want to swap gear ratios). I ended up going with a Quaife 3.46 LSD. Just ordered from Koala motorsports for $3700. Should be SWEEEEETTTTT!
