Guess you'd need to compare this to the HP plus.
I've measured the rotor temps at 460C with an IR thermometer after a cool-down lap on a slower track, so I have to figure at peak braking they are well north of 700C.

The HP Plus are only really rated to about 800C (Mu goes to basically zero past that I think!), whereas track-focused pads support up to about 1000C for something like the HP Street Race/Pagid Orange, 1300C+ for "real" race pads.
