If the clamping force between the rotor and pad is the same, the heat generation is the same. Race pads will activate ABS sooner, and more consistently, lap after lap. That's why lake braking is so much more effective, and fun, on race pads. And that's what causes higher temps, which leads to more heat soak. Said another way, you need less pedal pressure with race pads to generate the same braking performance as OEM.
I use high torque pads on all my track cars. Have for 15 years. Probably tried very brand under the sun. No fancy aftermarket cooling or parts. Just good, fresh fluid.
As for catching cars in the corners, just because you late brake doesn't mean you are not also able to trail brake. Good technique involves both. It's not one or the other. I would agree that your consistency to trail brake after a late braking event is lower. But if you get it right, the rewards are huge. And isn't that why we are doing this?

Yes: every thermal event usually also involves a chemical event.
If you decelerate an equal mass in a shorter distance you will produce more heat.
Nobody here has any heat issues with lower torque stock pads. Virtually everyone that upgrades to a high torque pads ends up with cooked pistons, brown calipers and sometimes cooked brake fluid. But like i said before, a type of venue will play a role. Also how much somebody pushes the car and what lap times they get will play a role.
Ive never said that late braking doesnt allow for trail braking. To the contrary. Trail braking is about moving the whole sequence of braking later and deeper on the entry. So very much part of effective "late braking" while maintaining proper balance and managing weight transfer for as quick a rotation as possible.
That's why a *smooth* initial bite, excellent modulation capability and release is a preferred characteristic of any TRUE race pad. Let's not confuse what resellers market as "race pads" to a Joe Public vs what race teams use.
Ditto caliper designs, rotors, cooling, etc. Cheers!
