The invention is directed to outside diameter piloting apparatus and method for concentrically aligning a disc rotor to a wheel hub. The pitch circle diameter of the annular piloting features is greater than the pitch circle diameter of the rotor mounting fasteners and the wheel studs of the hub. The outside diameter piloting feature allows a hub section profile which is smooth and continuous between the inboard side of the wheel hub up to the mounting fastener apertures. This smooth and continuous profile reduces stresses and increases the fatigue life of the wheel hub.
