Product Line Details: Gray Armor-Plate, Premium

The Gray Armor-Plate, Premium line from Perfect Stop focuses on delivering durable disc brake rotors with enhanced surface protection. This product line features rotors with a smooth surface finish and vented design to optimize heat dissipation and reduce brake fade. The premium coating helps resist corrosion, extending rotor life and maintaining braking efficiency over time.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat more effectively during braking. The nominal thickness of 0.866 inches (22.0 mm) ensures structural integrity, while the discard thickness of 0.787 inches (20.0 mm) indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height measures 1.728 inches (43.9 mm), and it features four mounting bolt holes arranged on a 100 mm (3.937 inches) bolt circle diameter, ensuring proper fitment on compatible Nissan models. The smooth surface type promotes even brake pad wear and consistent braking performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan Note, Versa, and Versa Note
• Addresses brake noise caused by uneven rotor surfaces
• Improves braking performance by restoring proper rotor thickness
• Helps reduce brake fade during extended driving or heavy braking
• Prevents vibration issues related to rotor warping

Installation Notes and Tips

Ensure the rotor is installed on compatible Nissan Note, Versa, or Versa Note models using the correct mounting bolt pattern (4 holes on a 100 mm circle). Verify rotor thickness before installation to confirm it meets or exceeds the discard thickness of 0.787 inches (20.0 mm). Clean the rotor surface to remove any protective coatings or contaminants before mounting. Proper torque specifications should be followed for mounting bolts to avoid rotor distortion.
