I spotted this on YouTube this morning. It show how cracks can start in the holes of a cross-drilled rotor. The rotor probably was junk in the first place, putting holes and slots in it did not help.

I am still on the fence about cryogenically treated rotors. In theory it sounds great, but I wonder if it is over kill. But, I have heard from some fleets and race teams that swear by the rotors. This Tech tip makes a good point about DTV and brake pads. Warped Brake Rotors? Are You Sure? Before you...
