are they all standard option colours on bmws?
i fancy getting my brembo 6 pots and 4 pots redone on my merc, mine came in silver and are still in good condition but facelift model c63s with the factory performance pack upgrades usually come with red calipers.
i wasnt sure whether to go to the trouble of complete stripdown for powdercoating or just mask up and respray but i thought it would cost more than that to get them powdercoated so maybe ill go for that, itll be a much harder wearing option,
