Rays in 19" for 1600-- maybe you can find a deal on used ones in decent condition. I suggest this forum, the 350z forums, zilvia, rbwheels, or vipstylecars.com (those are my routine go-to places when I'm getting new wheels).
If you want to buy
new new though, then you're a little out of luck with selection. That is, unless you don't mind fakin' the funk.
Good luck OP
