Detailed Product Description

This Raybestos disc brake rotor (part number 980663) is specifically designed for use on Nissan and Infiniti performance models such as the 350Z, 370Z, G37, Q60, and Z. The rotor features a vented design that helps dissipate heat during braking, reducing the risk of brake fade under demanding driving conditions. The smooth surface finish ensures consistent pad contact and braking efficiency. The drum-in-hat configuration integrates the parking brake drum within the rotor, eliminating the need for a separate drum brake assembly.

Key dimensions include a nominal thickness of 0.787 inches (20.000 mm) and a discard thickness of 0.709 inches (18.000 mm), which define the usable rotor thickness before replacement is necessary. The rotor’s outside diameter measures 13.772 inches (349.800 mm), with an overall height of 2.441 inches (62.000 mm), ensuring proper fitment and clearance. The five mounting bolt holes with a 4.5-inch (114.300 mm) bolt circle diameter and a center hole diameter of 2.677 inches (68.000 mm) provide secure attachment to the vehicle hub.
