FD and RX-8 Diffs interchangeable?

That would be really nice if they are. I've been wanting a diff. set but IMO 4.3 isn't worth the money and 4.77 is just to much. I've always wanted something close to 4.5.

So the 4.44:1 isn't close enough to 4.5:1 for you?

Yes it is that's why it would be nice if it's interchangable.

Only the RX8 ring and pinion can be used as a replacement in an RX7 diff, you can not use the RX8 differential case or differential.

Hope this helps,
Dan
