Detailed Product Description

The Raybestos 980312 disc brake rotor is specifically designed for Toyota Prius models, providing a precise fit and consistent braking performance. This rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade under normal street driving conditions. The nominal thickness of 0.865 inches (21.950 mm) ensures durability and longevity, while the discard thickness of 0.787 inches (20.000 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height of 1.930 inches (49.000 mm) and outside diameter of 10.040 inches (255.000 mm) are engineered to match factory specifications for proper fitment and function. With five mounting bolt holes arranged on a 100 mm (3.937 inch) bolt circle diameter and a center hole diameter of 2.168 inches (55.050 mm), installation aligns with Toyota Prius hub assemblies. The conventional drum-in-hat rotor type supports compatibility with existing brake components.
