Just a thought…
Using a line lock braking system would have the main brake pads locked against the rotors. If the braking system was really hot when the car was parked, wouldn’t the hot pads on the hot rotors contribute to warping of the rotors? Not necessarily because of the hot pad against the hot rotor, the normal pad/rotor clearance is very small when the brakes are not engaged, but because of the clamping action of the hot brake pads on the hot rotors and the movement (expansion/contraction) of the hot rotors as they cool?
Cool-down laps at the track cool down the engine, exhaust, and the braking systems. Though admittedly much more severe heat conditions at the track, but more often on the street.
