Chassis and cradle is the same between non M E85 and 86, whether facelift or not.
Diffs from many different BMW's are an exact swap. I will be running an X3 diff for the first bit of this season to see if I like it. I have used an E46 diff in the past as well as an SMG diff from a 3.0si. There was a website around called BokchoysBMW for a long time with an interchangeability list on it, unfortunately it's offline now. https://www.e46fanatics.com/threads/...-gone.1288847/

is a 4.44 from an X3. Aftermarket likely best bet if stuck on 4.10.

That was their page when I was going through the different ratios when originally looking so that’s my next conundrum. All fun. |

That's an awesome website, thanks for sharing! I was always under the impression that the Z4M transmission was geared longer than the E46 M3's but it seems that there isn't really much of a difference to speak of at all.
