I have the sport package diff right now. I preferably would like to keep the same final drive ratio and get a 1.5 way. I don't know how you call it but the one I was talking about is the Nismo diff you can get from the dealer basically. Is there a better version available from the dealer too? What's the right part number? As for the Bell diff brace clearance, my exhaust is GReddy GT Evolution. Will this fit on my 370z?
