Holy %^*( good rims are expensive for your car, man!
I checked out tire rack, everything brand name is like $200 and up! I got my BBS wheels for $145 a piece, including shipping, they're charging $700 for one 18x8" BS rim. There's one I found that looks really awesome, but it's $300 per wheel. It's 16 pounds, though. Anyway, if you check them out you can see the wheels on your car, it's kinda cool.
