dude your fenders won't get jacked up if you have them rolled correctly (w/heat gun) and patiently. a nice flat roll and you wont even notice from the outside that they've been rolled... it's when guys apply more pressure to get that pulled look.

there's got to be someone around your area with rolling experience.. normally will run about only $45-75 to roll the rears. it is most definitely worth it. a roll and a simple tab relocation and then you can run a 255 and 20mm spacer w/no problem
