i stated for "street use".
i guess Porsche Carreras, Brembo, Stoptech, Rotora, Wilwood are all behind the times too huh?
Porsche, BMW, and Mercedes rotors are molded with the holes in them so the grain of the metal aligns around the holes. Cross drilled rotors are drilled after the rotors are molded so the holes go through the grain of the metal thus making it easy for for cracks to develop around the holes.
