Detailed Product Description

The Raybestos R-Line 980740R rotor is a vented disc brake rotor featuring a drum-in-hat design, which integrates the parking brake drum within the rotor assembly. This design is specific to certain Saab 9-3 and 9-3X models, providing both braking and parking brake functions in one component. The rotor has a smooth surface finish to ensure even brake pad wear and reliable friction. Its vented construction improves heat dissipation during braking, reducing the risk of brake fade under demanding conditions.

Key dimensions include an outside diameter of 291.7 mm (11.484 inches), an inside diameter of 203.5 mm (8.012 inches), and an overall height of 43.6 mm (1.717 inches). The nominal thickness is 20.0 mm (0.787 inches), with a discard thickness of 18.0 mm (0.709 inches), indicating when the rotor should be replaced to maintain safe braking performance. The rotor mounts with five bolts on a 110 mm (4.331 inches) bolt circle diameter, matching the factory specifications for the Saab 9-3 and 9-3X.
