I like the Enkei RPO-2j's. They have the 18x8" for F but no 8.5" for rear?

Who else make cheap/light wheels in 18's?

 

I have a performance model so I ended up with the RPO2J's on all four corners. Wasn't much out there in the 18x8" size.

If I recall, SSR Comp's run in an 18X8.5", but not in an 18x8". Not sure of their cost.

BBS RG-R may also be a viable choice.

This site seems to have good information on the different sizes available:

Good Luck!
