WTF is wrong with my brakes?

BGTV8

Brake temps are the issue - have you fitted ducted cooling air from the front fascia to the centre/back of the rotors ?
Tracking for 25minutes even with modest skill is about the same as driving hard down a mountain ..........
You do need to look after your brakes and that starts with managing temps for rotors, pads and calipers/fluid

And to answer your question, there is nothing wrong with your brakes, they've just got too hot.
