A good friend is very (extremely) quick at autocross, but we would rib him for his track times at Portland International Raceway. He used HP+ with no issues. I tried HP+ once in my car at PIR, overheated them on the third lap. With even a stock power miata you should be able to overdrive HP+ pads unless the track is super easy on brakes.
