• Outside diameter of 12.59 inches (319.7 mm) suitable for specific INFINITI and Nissan models
• Five mounting bolt holes with a 4.5 inch (114.3 mm) bolt circle diameter
• Non-directional brake surface for versatile installation
• Conventional rotor type without ABS tone ring

Detailed Product Description

The DuraGo BR900718 disc brake rotor is constructed from full cast iron, providing a durable and heat-resistant braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking and reducing the risk of brake fade under heavy use. With a nominal thickness of 1.1 inches (28 mm) and a discard thickness of 1.02 inches (26 mm), this rotor meets OEM specifications for thickness and wear limits. The rotor measures 12.59 inches (319.7 mm) in outside diameter and features five mounting bolt holes arranged on a 4.5 inch (114.3 mm) bolt circle diameter, ensuring proper fitment on compatible vehicles.

This rotor is designed as a conventional, solid disc without cross-drilling or slotting, and it does not include an ABS tone ring. The non-directional brake surface allows for flexible installation without concern for rotor orientation. The overall height of 1.94 inches (49.3 mm) and center hole diameter of 2.68 inches (68 mm) align with factory specifications for the listed INFINITI and Nissan models.

Compatible Vehicles and Applications

This DuraGo disc brake rotor is compatible with a range of INFINITI and Nissan vehicles, including:

• INFINITI 370Z, EX35, EX37, G25, M35h, M37, Murano, Q40, Q70, Q70L, QX50, QX70
• Nissan 370Z and other models sharing the same brake specifications

Common Issues Addressed by This Rotor

• Brake rotor warping causing vibration during braking
• Excessive brake noise due to worn or damaged rotors
• Reduced braking efficiency from rotor surface wear
• Overheating and brake fade during extended braking
• Uneven rotor thickness leading to pulsation or poor pedal feel

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.02 inches) before installation
• Clean rotor surface to remove any protective coating or debris prior to mounting
• Torque mounting bolts to manufacturer specifications to avoid rotor distortion
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a proper bed-in procedure after installation for optimal braking performance
