I recently rebuilt an E46 M3 diff with new Bearings and Seals and then two weeks back i rebuilt my Z4 M Coupe diff with all new seals and Bearings.... I can confirm for sure that the M3 diff and Z4 M Diff are not the Same...
These are the things i noticed while doing the rebuilds:
> Both Diffs look the same but the Z4 one uses a slightly different case and back door...but has the same mounting points as the M3 diff (2 rear and 1 front) ( also saw this when i tried to use an M3 gasket on the Z4 Diff cover - there are slight changes on the two)
> The LS Units/Carriers are completely different with the Z4 showing a Meaty carrier with more clutch packs than the M3.
> Also looks like the inside of the Z4 case was machined on the sides to allow the Bigger thicker LS Unit to fit in the Z4 diff Case.
> The bearings that i ordered for the M3 was completely different part numbers to the Z4.
