Thinking about buying X-drilled rotors to improve the looks of my wheels and was just wondering if Brembo's were drilled before or after casting vs stillen's that r drilled after being casted. The reason is if it's done after,won't that technically speaking,compromise the structure of the rotor

The Stillen rotors are Toyota rotors that are "precision" drilled w/ a CNC machine and have a tapered edge to help prevent cracking. But I'm not sure how the Brembo's are cast or drilled.
