At 2.7 I'm pretty sure at least the top of your tires will be tucked in the front, so you might want to get your fenders rolled. I have a buddy with a teg w/ 18s and he got his rolled for something like $150, but that was while it was in the shop for something else anyway.

Just about everyone on here will tell you to go smaller for rims, at first i thought oh yeah 18s will look cooler, but there are ALOT of negatvies to the bigger rims. do a search and read up. Have you seen pics of 17s and 18s on your style car?? I reccomend going down to 17s w/ 40 series tires, but thats just my opinion.
