All the Porsche drivers I know (911s, 944s, 968s) remove their stock cross drilled rotors for driving schools. I don't care how you make the holes in the rotors, you can't keep cracks from happening. True, casting them into the rotor helps. Cryo treating x-drilled rotors help. But you cannot eliminate cracking on x-drilled rotors.
BTW, these Porsche drivers usually take those stock x-drilled rotors on track one time. After they crack them from a weekend of abuse, they find out that replacements cost ~$800.
