Thanks for the input.
I traded emails with MikeThePowderCoater and he advised that for a track-used car I might want to skip powder coating due to heat making the powder coat tacky which then causes brake dust to stick to it. His price was very good tho.
I don't think I $800-care about having a different color set of calipers. For $200 it would be nice, but my car isn't a show car so I don't care enough to invest in the cost of a new set of rotors.
