ZPOST - View Single Post - E46 M3 M-Diff vs E86 Z4M M-Diff ... differences?

sixspeed · 06-03-2010, 09:23 AM

I was fairly certain that the diff on our Z4Ms was the same item from the E46 M3?

However they have different part numbers as listed by BMW?

Are they interchangeable?

Are there any differences to the casing/mounting/internals?

Basically I'm wondering if you can fit an E46 M3 diff to a Z4M, and vice versa, as a straight-swap, without any modifications?
