Heat is what causes the rotors to warp. Some brake rotors do have improved materials, but BBK has larger surface area (and in most of them the rotor is thicker as well). Idea behind slotting / etc is to increase surface area and improve ability to remove heat from the rotors. El cheapo dryer hose brake cooling kit could probably help here too- probably not in character with pimpin’ in an Infiniti M though LOL
