Interesting to watch, thanks for sharing that. Surprised at how easy the surface of the tread cools on a straight (esp for the non-driven wheels).
Check out the disc brake temperature display. A nice insight into the physics of racing car. The information of disc temperature is important for calculating the break factor. Image source. The break factor is inversely proportional to disc temperature.
I'm unsure which way to read that brake factor. Is a higher or lower number better? As I'd expect there to be an optimal temperature (or tempertaure range), above or below which the force reduces.
