Cross drilled rotors should have the hole counter sunk to help prevent rotor craking.. Both cross drilled and slotted rotors serve the same function.. that of removing pad gas build up when the brakes get really hot
.. not something you'll see in street driving and rarely, if ever, with our cars on the race track..
just something for show and having both drilled and cross slotted on the same rotor is really dum..
