The Trophy calipers are not painted or powdercoated. They have a MIL-spec, hard-anodized finish that will not fade or discolor even at professional level racing temperatures. But they're not impervious to an acidic environment. Paint is better at acid resistance.

StopTech red or black calipers use a 2-part, high temperature epoxy that does well at the track. Their silver, yellow, and blue paints aren't as robust at high temperatures. Similarly, the ability of powdercoat finishes to stand up to track use without color shifting or fading will depend on the color.

Silver paint (regardless of manufacturer) is not a good color for heavy track use. That's why the silver Trophy calipers are unique. Check out what happens when you track a Volvo V70R with factory silver calipers and light gray "R" logo:

Needless to say, this guy's wife (it was her car!) was not pleased.
