This is a pic of the SSR GT1:
This is my first choice. 18" package with Kumho tires from Tirerack is about 1900, 17" package is about 1750. Pricey to say the least, but the SSR series is SO much lighter than all of the other wheels as well, because of the Alumax SSF (semi solid forged) process used to create the rims. The 18" SSR GT1's in 42mm offset are only 17.8 lbs a piece. That is lighter than the stock wheels, the 17's are only 16.5 pounds. Nice. Decisions decisions...
