http://www.edgeracing.com/wheel/2422/ is selling Enkei RP02 18x8/+35 wheels for $125/ea. I ordered one for test fitment over the brembo brakes. It's tight with 2mm of clearance between the spokes and caliper. Spacers are probably recommended. The wheel registered 19 lbs (5 lbs lighter than stock) on my bathroom scale. Advertised weight is 18.8 lbs.

I have no affiliation with the seller.

 

That is a great deal!
