Detailed Product Specifications

The Raybestos 66474 rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade on street-driven Ford Mustang vehicles. The rotor’s nominal thickness of 0.720 inches (18.300 mm) ensures durability and consistent performance, while the discard thickness of 0.661 inches (16.800 mm) indicates the minimum safe thickness before replacement is necessary. With an overall height of 2.010 inches (51.050 mm) and an outside diameter of 11.660 inches (296.150 mm), this rotor fits precisely within the brake assembly. The mounting bolt hole circle diameter measures 4.500 inches (114.300 mm), accommodating five mounting bolts with a diameter of 0.578 inches (14.700 mm). The center hole diameter of 2.785 inches (70.750 mm) ensures proper alignment on the hub. This conventional rotor type is designed for vehicles with five lug studs, matching the Ford Mustang’s specifications.
