i have a 01 ss and a 95 big single supra. The supra get drilled and slotted but i dont on the monte. Ill explain. The main reason for cross drilling a rotor is to loose weight. Now by having rotors that are drilled they can no longer be safely turned. The now as for slotted rotors they are good for moving hot gasses and kepping them from pocketing and causing overheat. For a daily driver cross drilled and slotted are a bit over rated. Just go for a good set of rotors and Hawk pads and youll be happy
