Zo6 wheels... mods needed

[94CamaroZ28]

Has anyone here put 18x10.5 (more specifically ZO6) wheels on the rear of the a 4th gen camaro. I heard about someone putting 17x11 ZR1 wheels on a 4th gen, but he had to flair the fenders and hammer in the inside of the wheels wells. Anyway, I have already ordered them... I'm just wondering if I should expect to have to do any customizing. here is the link to that camaro with 315's... mine will be 295's...
