You will definetly need to roll your fenders, I had a 98 and had a bunch of rubbing on the tire...Remember pete?? Once you roll you should be fine...but make sure you roll the back sufficiently enough, because when you put people in the back seats or a load in the trunk it will start rubbing again if you did not roll well enough!

Good luck, 18's really do look the best...I've had 2 sets of 17's and 1 set of 18's.
