as far as I understood the single parts aren't available by BMW, only the complete diff. Unfortunatelly I found only a normal 3.85 M3 6MT diff at the scrap complete with all the subframe, harms, brakes and half shafts..

I know two people that have installed the Dinan 3.62 and have the 3.15 sitting. Their prices are unreasonable at the moment but I am sure soon the used market will have plenty for cheap.
These are the ratios currently available from diffs online:
2.65 _
2.81 _
2.93 _
3.15 _
3.23 _
3.45 _
3.62 _
3.85 _
3.91 _
4.10 _
4.45 _
4.75 _
I think its essential that everyone researches M3 diffs as I know of a few people that have had to swop theirs out under warranty. So it might sound exciting and all but is the diff superior to a OEM 335 with a LSD.
