I'm in the process of getting an EvoV to build a time attack car over here, and I've got just a question.
I've read somewhere, USDM rear diffs don't have the AYC as standard. Is that true? I want to fit a non-AYC diff on the V, but RS' units are quite expensive and hard to get by. So, ideally, I'd get a US rear diff and fit a nice LSD on it.
Any help?

 

My friend just slapped an entire rear diff / case he bought from the states into his Evo 6 RS. Worked perfect. Yes as far as I know, no AYC in the states.

 

Great! That's what I needed
