I have searched everywhere and can not find the answer to this question. I am running the 350Z Eibach Pro Kit and the stock 18x8 et30 wheels (04 G35 coupe). My question is, can I run a 25mm spacer in the rear without rolling the rear fenders? Or will they definitely need rolled? Stock tire size in the rear as well 245/45/18. I just hate the way they look tucked into the car and want to pull them out some.

I have searched and searched and have used the wheel offset calculator to compare it to other wheels but haven't been able to come up with an answer. Any info would be great!
