Weird Marks on my Rotor

BGTV8

If you park the car after a track session or a hard-drive and walk away, you will get heat-soak under the pads into the rotor. At a track day. I always carry a small piece of 40mm square timber (an offcut is all that is required) to stop the car rolling away when parked on the pit apron, and every 1 or 2 minutes, push the car 2 feet and re-chock the wheel - move the vehcile enough to rotate the wheel by (say) 90 degrees and shift the pads to another segment of the rotor - this allows the whole rotor to cool more uniformly that it can otherwise.

Is also a good option to not apply the handbrake when the rear rotors are ultra hot.
