Hmmm...I dunno, I think it's a MUST to paint calipers/drums.(obviously) But I painted everything jet black on my carbon blue celi. I think it looks a lot cleaner. Even the inside of the face of the rotor.
The blue looks alright IMHO, but if I were to go any other color than black, it'd prolly have to be red over anything else.
Isaac, where'd you find pic? (and more importantly, how come you never w/b anymore...my feelings are starting to get hurt)
