For the e36 it can either be a 168mm (small casing), a 188mm (medium casing) or a 210mm (large casing) ring diameter, the e46 LSD has a 210mm ring diameter.
Thanks for the information, Terra. I think I'm going to hold out and get the M3 rear and swap the 210mm 3.15;1 R+P.
Still looking forward to the results of this. Keep up the great work, Brady!
Edit: Is "Mr. Wizard" Wanganstyle?
