Anyone know of good factory replacment cross drilled slotted rotors?

i installed slotted and cross drilled rotors on the front and the back of my dart. More for looks than anything. I just contacted master power who i bought my brakes from and spoke with their tech line. They have never heard of any of their rotors cracking around the drilled holes and said that their rotors are turnable by anyone who knows how to properly operate a brake lathe?

Who's bsing who?!?
