Which back diff LSD directly bolts on for xDrive with 6MT? I don't want different ratios between front and back final drives.
On the other hand, which LSD (Torsen type) fits for front diff? Torsen is perfect for front because it transfers torque to MORE grippy side but doesn't LOCK in like clutch or liquid types.

While the overall thrust of this post is correct, there are major flaws.
1) BMWs don't come with a "center" diff. It's a transfer case, and it'w always creating some windup between front/rear that is only relieved by tire slippage.
2) There are no LSD's that fit within the very special front differential case. (AFAIK)
