New diff rebuild / swap needed

[kokgo20]

Hello everyone,
I have been away from the forums & my M3 for a a couple of years, which I'm sure a lot has changed.
I need recommendations on Diff rebuilds or swaps as mine has all sort of issues now.
It's mainly street / few track weekends per year.
Is Diffs online is still about the best builds out there?
Anyone who does reliable rebuilds that would ship?

Thanks in advance!

What are the problems?

I read about diffs online and metric mechanic, or even racing diffs but being abroad shipping would be expensive

Leak, clunk, loose flange.
i have been wanting something better for while
