RE-71R is a cheater Auto X tire. It's actually quite a bad track tire because the optimal temperature range is so narrow. They have incredible grip but go greasy after just a few maximum attack laps.
I've posted this in a ton of threads, but right now the best semi-track tire is the Cup 2. Dirt cheap right now in the OEM fitment. https://www.prioritytire.com/michelin-pilot-sport-cup-2-245-30r20-zr-90y-xl/
OP, to answer your question, the stock pads are not up for a 30 minute run at maximum attack. I can't do more than 6-7 fast laps at AMP (home track - lap times are in the mid 1:30s and it is not a heavy braking track) before getting some pretty gnarly fade. Car still stops but the braking distance begins stretching out after lap 5 or so.
If you run the heater on max, the car generally won't go into overheating / limp mode during a 20 minute session (haven't run longer than this due to brakes), even in hot weather (90F with 85% humidity). However, the coolant temps will get quite high, and the gauge (at least on the 2019s) does not provide any actual numbers, nor does it provide oil temps, so you may be cooking the oil.
The stock tires will roll over onto the sidewall and also horribly overheat if you are driving hard. Even if you overinflate, you can't fully stop the rollover, and overinflating them makes them get greasy even faster. You have to be very careful once they become greasy, because the resulting understeer will shred the sidewalls and tread. My stock front right (counterclockwise circuit) was absolutely cooked at just 2700 miles because of this phenomenon.
