Only one way to find out! Of all the paints I've researched I would think that the two-part G2 has the best chance of surviving race temperatures. Check their websites for temp specs. I saw what racing does to the stock blue paint on M Sport calipers. The heat turned half of the caliper a greenish color.
Powder coating is another option but I'm not sure what the high temperature specs on powder coating are. I know that Brembo promotes their paint process over powder coating.
Oh, also the color chosen also has an effect. I recall a powder coating guy telling me that silver is the worst color to put on a brake caliper because it won't hold up.
Another option for high heat race calipers would be to ceramic coat them. Less color options but heat would have no effect. I have photos of my downpipe ceramic coated and a photo of ceramic coating color samples. But I haven't been about to upload a photo to Bimmerpost for the past day or two since they were down for maintenance.
