Detailed Product Description

The DuraGo BR900748 disc brake rotor is constructed from full cast iron, providing a solid and durable braking surface suitable for a range of mid-size and performance vehicles. Its vented design enhances airflow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. With a nominal thickness of 1.18 inches and a discard thickness of 1.06 inches, this rotor maintains structural integrity throughout its service life. The 12.64-inch outside diameter and 2.01-inch overall height ensure compatibility with specific Buick, Chevrolet, GMC, and Saab models, including the Chevrolet Corvette, Buick Regal, and Saab 9-5. The rotor features five mounting bolt holes arranged on a 4.72-inch bolt circle diameter, matching factory specifications for secure installation. This conventional, non-directional rotor does not include an ABS tone ring and is not cross-drilled or slotted, making it a straightforward replacement part for vehicles requiring standard rotors.
