Detailed Product Description

The DuraGo BR900460 disc brake rotor is engineered to meet the specifications required for Mazda RX-8 vehicles. Its full cast iron construction ensures durability and effective heat management during braking. The vented design allows air to flow between the rotor surfaces, reducing the risk of brake fade under heavy use. With a nominal thickness of 0.71 inches and a discard thickness of 0.63 inches, this rotor maintains optimal performance throughout its service life. The rotor features five mounting bolt holes arranged on a 4.5-inch bolt circle diameter, matching the Mazda RX-8’s factory specifications. This rotor does not include an ABS tone ring and has a non-directional braking surface, allowing for flexible installation without concern for rotor orientation.

Common Applications and Problem Solving
