dude, if you meant to say 18x9.5, get ready for those badboys to rub like no other, unless you don't plan on dropping your car at all. If I remember correctly, I called in on those and the offset is +45. You will have to go with a 225 or 235 tire for sure, maybe 245, but find out before you buy anything, it sucks ass when your tires rub, I know.

I have the HP Design Evo version of those wheels. 18x8, +40mm, and 235 tires. I'm lowered about 2" and these tires rub on dips, etc.

Be careful.

If you want some good pictures of how these look on an eclipse, lemme know, send me a PM, I'll send you some good links.
