Yes, your heater core with the fan on will act as another radiator. By using the defrost mode, it blows hot air over your head where you won't feel it as much. Other trick is open passenger vents, point them toward the window and close driver side vents. You will be driving with windows open, so you don't notice the extra heat in the car. The sitting with hot brake pads is good advice. Not so sure about warping rotors, but you do put a pad brand mark on the rotor which will feel like a bump or pulse through your brake pedal. Try not to sit in line coming off track with your foot on the brake for more than a second or 2. Cool down lap is just that. Cool down. then park your car in gear with no brake. If paddock isn't flat, have someone grab a block and stick under your tire.
