Powdercoat all of it
I swapped my brakes this last weekend, the calipers are powder coated electron blue pearl. Also added a new MC and booster... MC because it had 160K miles on it, booster because I accidentally hit the original while installing a set of gauges. The front rotors are ACDelco for now, matching grooved rotors have been ordered... I had these laying around and wanted to get it going. Someday I'll have enough posts to list my 05 OEM calipers for sale... I'm debating stripping them and powder coating them for the next owner. The OEM red seems dark and less than impressive.
