• Solid disc brake rotor design for durability
• Geomet rust-resistant coating to prevent corrosion
• Nominal thickness of 11.50 mm with a discard thickness of 9.90 mm
• Outside diameter of 320.00 mm (12.60 inches)
• Mounting bolt hole circle diameter of 114.30 mm with 5 lug holes
• Overall height measures 41.50 mm (1.60 inches)

Detailed Rotor Specifications and Features

This Power Stop rotor is a solid type, providing a consistent braking surface without venting. The nominal thickness of 11.50 mm ensures adequate material for heat dissipation and wear resistance, while the discard thickness of 9.90 mm indicates when replacement is necessary to maintain safe braking. The rotor’s Geomet coating offers enhanced protection against rust and corrosion, which is especially beneficial for rear rotors exposed to road elements. With an outside diameter of 320 mm and a mounting bolt hole circle diameter of 114.30 mm, this rotor fits securely on the rear hubs of compatible Ford Mustang vehicles.

About the Power Stop - Rear Genuine Geomet Coated Rotor Line

The Power Stop - Rear Genuine Geomet Coated Rotor product line focuses on providing rotors with a factory-style Geomet coating that resists rust and corrosion. This coating helps maintain rotor integrity and appearance over time, reducing the risk of premature rotor degradation. These rotors are designed to meet or exceed OEM specifications, making them suitable replacements for rear disc brake rotors on Ford Mustang models requiring reliable braking components.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Ford Mustang vehicles
• Addresses rotor corrosion issues due to environmental exposure
• Improves braking consistency by restoring proper rotor thickness
• Eliminates brake pulsation caused by uneven rotor surfaces
• Suitable for routine maintenance and brake system overhauls

Installation Notes and Tips

Ensure the rotor mounting surface and hub are clean and free of debris before installation. Verify the rotor thickness is within the nominal range and replace if below the discard thickness of 9.90 mm. Use the correct torque specifications for the 5 lug bolts on the 114.30 mm bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking performance.
