I have an 02 gt convertible with the rear quad shocks. I was thinking of going with a set of chrome 03 cobra wheels. they are 17x10.5 w/ 315-35-17 tires in the rear. I would really like to buy these but I don't want to have to use a spacer. If these won't fit because of the quad shock what is the largest rim and tire that I can go with. thanks for your help.
