Detailed Product Description

The Raybestos R-Line 980863R disc brake rotor is a vented, conventional rotor designed to meet the braking demands of specific Mazda vehicles. Its vented construction allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade. The rotor features a smooth surface type, ensuring even contact with brake pads for consistent stopping power.

With a nominal thickness of 0.906 inch (23.0 mm) and a discard thickness of 0.827 inch (21.0 mm), this rotor provides a clear service life indicator to maintain safe braking performance. The rotor’s outside diameter measures 10.154 inches (257.9 mm), and it includes four mounting bolt holes arranged on a 100 mm (3.937 inch) bolt circle diameter, compatible with the specified Mazda fitment. The overall height of 1.728 inch (43.9 mm) and inside diameter of 6.516 inch (165.5 mm) ensure proper fit and function within the brake assembly.
