Have you considered buying temp stickers to stick on your stock calipers, see how hot you are toasting them?
If it’s over oem size rotors, the benefits I can see would be the GT calipers are bigger heat sinks, and may provide better/finer brake modulations at threshold.
To be honest, especially at your power level, I would do full setup (calipers and bigger rotors) for higher heat capacity.
