Are you looking for OEM 18" wheels or aftermarket? You can check the classifieds here, but most of the sales are 19"+ it seems. I found my 17" OEM wheels on craigslist, but proceed with caution. Tirerack.com and discounttire.com are good sources of aftermarket wheels, but be sure they clear the front brakes. If you search here, you'll also find an aftermarket source of reasonably priced OEM-style 18" wheels in hyper black or hyper silver that folks have had good luck with. Happy hunting.
