I'm partial to GSR wheels OR clean wheels, 14's-16's. You could always get the 94-95 fat fives and have them powdercoated gunmetal. I've also seen the Blades in gunmetal and they are pretty sexy. I'd get anything clean, either gsr wheels or something aftermarket in a 16, and gunmetal definitely looks awesome on black cars.
Factory rims is the way to go!!, Look awesome, dont get stolen as much
