cross-drilled and slotted rotors help when your brake pads get too hot and start outgassing. I think that's the word. Anyway, with a normal, flat brake rotor the gas gets between the pad and rotor and reduces your braking effeciency. with slots/holes, the gas can get out.
also, people like to say that drilled rotors cool down better/faster. but with a drilled rotor, there's less overall rotor mass, blah blah blah, warped rotor, blah blah blah.
that's just my knowledge, I could be wrong.
