Technical Specifications and Features

This vented disc brake rotor features a smooth surface type and a nominal outside diameter of 330 mm (12.992 inches), suitable for heavy-duty braking applications. The rotor’s nominal thickness is 22.000 mm (0.866 inches), with a discard thickness of 19.400 mm (0.764 inches), indicating when replacement is necessary to maintain braking efficiency. The overall height measures 62.700 mm (2.469 inches), and the rotor includes a center hole diameter of 67.000 mm (2.638 inches) for proper mounting. The rotor is designed with five stud/lug holes, each 15.300 mm (0.602 inches) in diameter, arranged on a 112 mm (4.409 inches) bolt circle diameter. The straight vane style promotes effective heat dissipation during braking, reducing the risk of brake fade.
