• Vented disc brake rotor for improved heat dissipation
• Overall diameter of 10.039 inches (255 mm) for exact fitment
• Nominal thickness of 0.866 inches (22 mm) with discard thickness at 0.748 inches (19 mm)
• Four mounting bolt holes with a 100 mm (3.937 inch) bolt circle diameter
• Center hole diameter of 2.165 inches (55 mm) for proper hub alignment
• Conventional rotor type compatible with drum-in-hat brake systems

Detailed Product Specifications and Features

This Raybestos R-Line rotor (part number 980476R) features a vented design that enhances cooling during braking, reducing the risk of brake fade under normal driving conditions. The rotor’s overall height measures 1.811 inches (46 mm), ensuring compatibility with the brake caliper assembly on compatible Toyota and Scion models. The four mounting bolt holes and lug holes provide secure attachment, with a bolt hole diameter of 0.573 inches (14.55 mm) to match factory hardware. The nominal thickness of 0.866 inches (22 mm) allows for a balance between rotor strength and heat dissipation, while the discard thickness of 0.748 inches (19 mm) indicates when replacement is necessary to maintain braking safety.
