When doing my rear I was tossing up between the quaife and the Nismo GT pro. I went the Nismo because the Quaife in the rear was just released and there was no feedback around, despite how good it was up the front.The Nismo, on medium is way too much, I need to back it off and to get back that front drive that the quaife gave prob need to throw some extra friction plates into the transfer case. The Nismo (Atleast on medium) is one agro mofo.
How the quaife would go as a rear, it won't be a bad thing, may be super special but there isn't many people running one as they are so new.
