Making a cheese slicer out of rotors does not mean that it will stop any better. It will remove heat and other things that are created during the stopping process better. I would bet the aftermarket crossdrilled will crack between the holes. The surface area of the rotor and contact with the pad provide the stopping force, so removing this with holes and slots would be contrary to this idea. Just my two cents but I am wrong often.
