3.73 LSD on 318is and my Sepang track outing

[Stu]

3.91 came in the ix, i have one on my parts car...its kind of high miles but the rear end of ix's don't take much abuse.

How many miles? Any interest in a sale?

BTW, Matt's 3.91 came out of a limited-slip equipped early model 318i.

also came in the US-market e28m5 (supposedly what mine's from).

not that that's any easier to find...

actually i got quite a discount on this diff. I got it from e30matt, a good friend of mine. It had just been rebuilt 10k miles ago, and he didn't need it seeing that the PO of his car put in a 4.10 big case LS diff. It was just taking up space in his garage so i got it for $50. We put it in that night and all we had to buy was alittle diff oil. Cost me $56.00 total i think. But once again, this was a freakin steal.
