Are you all that are runnin the 315's using a 10" rim? My budget for next year includes the money for some real 18" Saleen wheels. I want to run 315's in the back and 265's up front with some Nitto 555 rubber. So 265/35/18 and 315/35/18. How about wheel spacers, is it just for the look or are they necessary? I'm running 2.5" tails with no suspension upgrades. The last thing, this rolling fender part I keep hearing about, would my particular case require it? Any answers would help guys, thanks.
