I was considering on getting some Enkei RPF1's. I was thinking about 17x7.5 +48 for the fronts and 17x8.0 +48 for the rears. I'll be running 225's in the front and 255's in the rear. Will this fit without rolling the fenders and rubbing?

 

You would need a wider rear wheel to run the 255. They are available in the 17X9 but you would need to roll the fender lip or run more negative camber. The 17X8 with the 245/40R17 and a little negative camber would be an easier fit.
