Gray Armor-Plate, Premium Product Line Details

The Gray Armor-Plate, Premium line from Perfect Stop focuses on delivering durable rotors with enhanced corrosion resistance and structural integrity. This product line features a protective gray coating that helps reduce rust formation, extending rotor life and maintaining performance under demanding conditions. The premium vented design aids in heat management, which is critical for maintaining braking efficiency during extended use.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively than solid rotors. The nominal thickness of 0.984 inches (25.0 mm) ensures sufficient material for durability, while the discard thickness of 0.906 inches (23.0 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height measures 1.78 inches (45.2 mm), and it features four mounting bolt holes arranged on a 4.25 inch (107.95 mm) bolt circle diameter, compatible with the specified Ford models. The smooth surface type promotes even brake pad wear and consistent braking response.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Ford EcoSport and Focus vehicles
• Addresses brake pulsation caused by uneven rotor surfaces
• Helps reduce brake fade through improved heat dissipation with vented design
• Prevents premature rotor corrosion with Gray Armor-Plate coating
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is above the discard thickness of 0.906 inches (23.0 mm) to maintain safety standards. Use the four mounting bolt holes on the 4.25 inch (107.95 mm) bolt circle diameter to secure the rotor properly. This rotor does not include an ABS tone ring, so confirm compatibility with your vehicle’s ABS system. Follow manufacturer torque specifications for mounting bolts to avoid rotor warping.
