Message	On STOCK sized (drilled, slotted etc) blanks it does NOT make a damn bit of difference. Why? Because rotor "direction" is determined by the direction of the vanes INSIDE the rotor and not the pretty slots or drilling in them. Stock blanks and any modded rotor based on them have non directional vanes (they go straight out from the middle to the outside). On the Skyline rotors, Brembos, StopTechs etc, ANY rotor w. directional vanes they should be mounted so that their rotation is like this: The StopTech AeroRotors® are directional. If they are not installed on the proper side of the vehicle, airflow will be restricted and cooling will be severely diminished. The vanes on a rotor act like a centrifugal air fan, drawing air from the inside of the rotor and flowing it to the outside. The vanes of a directional rotor should arch back like arms on a pinwheel. On the top side of the rotor, the vanes should curve toward the back of the car.
