Love the new black monzas - I prefer them over the TD pro race. Do wonder what those monza's would look like with a red stripe though.
As for painting the hubs, I'd say to paint them a contrasting colour to the wheels/car. Bit difficult coz you've got to match both red and back. I was gonna go for silver on mine but black would be nicer. Think red would be too OTT on my car. On yours though....
