My car has stock power and the stickiest tires I've run are 235 AD08s. Given your supercharged power and use of R-comps, I'm guessing those are going make a big difference on brake performance needs/stress. Frankly, I'm surprised you can run on stock calipers!

interesting, in my case it starts fading after couple hot laps but maybe it's due to the more aggressive tires like you mentioned..since the stopping distance is exponentially effected with speed the faster you go the faster your brakes will suffer

Running on stock calipers and XP12s is not an issue even with the supercharger but only at RMP, PR and ORP is a whole different story but with the ST43s and new tires I can trailbrake a lot easier, I will eventually upgrade to a BBK of course

FYI, XP12s fade really really bad at 3A and 3B (Pacific Raceways)

@rever5e What size rotors are you running? I've got a line on some used ST40 332/32s I'm doing 1-2 HPDE/Motorkhana/Drift days per month and a reasonable amount of canyon carving. Looking at NT01 for track rubber. Cost for the kit is equivalent to used STI Brembos.
