For Sale: Freshly Rebuilt 3.15 V1 LSD - lower RPMs for highway driving, swaps, and turbo'd cars

[bigjae46]

I have a freshly rebuilt M3 diff. I swapped in a 3.15 ring and pinion gear. Relatively new - came out of a 13k mile E9X M3 DCT diff.

New genuine BMW seals and timken bearings and races.

The LSD is a V1 and has been rebuilt with the Racing Diffs clutch pack and small shim for the M clunk.

Does not include the rear cover.

The front bolt hole torques up but has the first couple of threads pulled out. You may want to do the 16mm bolt kit from Rogue Engineering.

$1200 shipped within the US plus $800 core charge.

Not a buyer but out of curiosity, any idea what ballpark RPM would be at, say, the 120-140mph? (I can't maths)
