If your brake components are working properly the stock setup is probably fine unless you are doing track sessions on hot days of more than 30 minutes. With 60+ track days on my car I just need to make sure the pads and rotors are in good shape and the fluid is fresh. The only time I overheat and boil my fluid is if I leave it in there too long.
My fault, not the cars fault. Typical track sessions with PCA Zone 8 are 25 minutes and the brakes are fine.
