The M3 LSD is so useless with a 3.62. When I repair my subframe this summer, I'll be shooting for a 3.23 LSD, so hopefully this gains some great momentum in the near future!
The E46 M3 ring and pinion fits in the E39 M5 diff, so I would think the E39 M5 r&p would fit in the E46 M3 diff. If that's the case, you'd be able to get a 3.15 ratio.
