Hondagirl...car looks sweet. Very clean...like it a lot.
GuyX: U can't compare with the impact that 18's give you. Nowadays ur starting to see some cars come with 17's...18's still give u that aftermarket look.
I was thinkin 17 or 18 too...but my concern was ride harshness more than denting a rim. U should also keep the type of rim u buy in mind. If you buy light rims, they're great to race, but dent easier. (I dunno why you'd be buying 18's if you race...uhhh...whatever...)
Btw, I'll guess 215/40/18...am i rite?
