haha, Wink, there is a fair difference in price between tempe rims and jap rims. Ie, cheap ass, good for street rims from tempe in 18's will cost you $2k ish with rubber but some nice forged jap rims withOUT rubber will cost you $1200ish per corner... but, you do get what you pay for.
I had 18x9.5's and 18x8's on my Gtst when I had it (265/35/18 & 245/40/18).
Hope that helps.
