315's
 

hey everyone, i am looking to buy ZR-1 wheels, 17x9.5 in front with 275's and 17x11 with 315's out back. i know someone that has 315's out back and i know u have to roll the fender edge. but is there any thing else major i am going to have to do to make these fit so they dont rub. i have a 96' formula bird and it has the factory suspension right now. but i am planning to get eibach springs and bilstein shocks and they say that will lower it about an 1 1/4 or so. please help. thanks

All I did was roll the rear fenders and hammer in the fender well slightly
