Yeah, the Chambers are pricey. Most retail shops want like $220 a pop, and with shipping it can be around a g-ball just for the rims! I do not think you can order direct from American Racing, at least I did not see an option for this on their site.
I bought some diamond plate rubber mats from Kragen and put these up front and took out the Isuzu carpeted mats. They don't fit EXACTLY perfect, but they look good nonetheless.
