I have a 2" drop on my car and I am looking into some 17s. I have seen a couple guys running Corvettte ZR1 wheels and what not. After reading another post, I checked out a website that gave me the complete dimensions for several Corvette and Camaro wheels. THe ZR1s for instance had like a 60mm offset and a backspacing of 6.8 - even with a 2" offset that's still 4.8! How are the guys running these wheels going with that much backspacing, or are they custon built/sized wheels? Dont you just want like 4" front and 4.5" rear backspacing? Also, I assume that you would need longer studs for that much of a spacer?
