One of the motorsports favourite techniques to improve the durability of an engine is a process know as cryogenic treatments. As you can guess from the use of the word Cryo - it involves the cooling and heating of the engine block to temper the metal changing its structure.

Cheers for that Rad, I hope that nobody got hurt after this treatment was done

My initial info is that the treatment works well/best when the temps are up but it takes a little longer to stop in a road driven car when the discs are cold.
The treatment is said to make the discs more stable ,last longer and reduce stresses that lead to cracking or warping.
