I hold a small workshops every couple of weekends or so. 2 or 3 cars.
Caliper paint colours I have here are Red, Yellow, Blue & Silver. 99% of people choose Red, it simply looks great on any car. This is what I recommend to most, as no one is ever dissapointed.
Others colours can be sourced if need be. Hubs can be painted colours too ($30/car).
EDIT - when I say workshop.. it's me working, and you guys talking
Cheers guys
Joey
