so i have been toying with the idea of putting a set of 19's on the rears. do you guys think it would look ok? i know alot of cars do it. but i havent seen many Z's like this. mabey one of you photo chop guys can chop this photo for me........PLEASE!!!

 

The 19s in the back will work just fine. 274/35/19s are the same height as the 275/40/18s you're now running. The sidewall height (the height of the rubber from the wheel to the tread) will be the same with 245/40/18s in front and 275/35/19s in back. I've thought of doing the same thing, but I'm happy with the way my 18s look and perform.
