S2000 diff options?

[Xcal]

I havent had my s2k for that long, but I read that the diff can be a weak spot. So my question is, what options are there out there for strengthened or after market diff casings?

Has anyone had any experience with stronger Diffs, be it fur use with FI or otherwise?

Thanks.

You can also contact Diff Technics about a locally manufactured option.

You do have a few choices though:
1) Spend $5000-8000 on an R200 solution or one of the other US conversions
2) Spend $2000-4000 having your diff rebuilt/reinforced
3) Don't abuse your diff
