I prefer the stock wheels, but that's just my opinion. Lots of people like black wheels.
Are you going to paint the entire wheel, or just the spokes? I don't like many black wheels, but some of the wheels that have black spokes with a silver/chrome ring that separates the tire from the wheel look pretty good, IMO. I don't know if you could do this with your particular wheel, or not.
I've been photoshopping exactly what blackdeuce is talking about. Everyone has their own tastes. I've come to the conclusion the stocks look equally as good. Not sure I want to mess with them, you know?
