Found this ad on craigslist Orlando. Super cheap, sweet looking rims in 4x114.3 (if there really off of a 280zx). Problem is, I live in Cocoa Beach and can't justify driving 60 miles to pick up a set of $15 rims, but I'm still curious as too who makes them and how much they could be worth.
The guy says they're "factory upgrades" for the 280zx, but they don't look like anything I've seen on stock 280zx's or 280z's. I'm thinking there oldschool aftermarket. Looks like they were originally gold.
