Embodiments of the present invention are directed to disc brake rotor assemblies which include disc brake rotor ring and a disc brake rotor hat. The disc brake rotor ring may include a first side including an inner perimeter and an outer perimeter, a first annular braking surface and a plurality of first mounting flanges positioned along the inner perimeter for affixing a corresponding portion of a rotor hat. Each flange may include an opening for receiving a fastener. The disc brake rotor ring may also include a second side parallel to and spaced apart from the first side thereby jointly defining a plurality of vents there-between, the second side including an inner perimeter and an outer perimeter, a second annular braking surface having and a plurality of second mounting flanges positioned on the inner perimeter of the for affixing a corresponding portion of a rotor hat. Each flange in the second side may also include an opening for receiving a fastener. Either the first side or the second side may be used as an outboard side when the brake rotor assembly is mounted on a wheel hub of a vehicle. In addition, the first mounting flanges may be alternately arranged and spaced apart from the second mounting flanges. The first mounting flanges and second mounting flanges are positioned in a central plane between the first side and the second side and the central plane is substantially parallel to the first side and the second side.
