Product Line Details: Power Stop - Front Genuine Geomet Coated Rotor

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances corrosion resistance compared to standard rotors, extending service life and maintaining braking efficiency. The vented design improves heat dissipation, which helps reduce brake fade during extended use. This product line is tailored for front disc brake applications on a range of domestic and import vehicles.

Technical Specifications and Features

The AR82126EVC rotor features a nominal thickness of 29.90 mm and a discard thickness of 27.00 mm, ensuring it meets OEM standards for thickness and wear limits. Its vented rotor design allows air to flow between the rotor surfaces, improving cooling and reducing the risk of overheating. The rotor measures 321.00 mm (12.60 inches) in outside diameter and has an overall height of 51.00 mm (2.00 inches). It mounts using a 120.00 mm bolt circle diameter with 5 lug holes, making it compatible with specified Buick, Chevrolet, GMC, and Saab models.

Applications and Problem Solving

• Replacement for worn or warped front disc brake rotors on Buick LaCrosse, Regal, and Allure
• Restores braking performance on Chevrolet Camaro, Equinox, Impala, and Malibu with front disc brakes
• Addresses brake noise and vibration caused by rotor surface irregularities
• Prevents rust and corrosion-related rotor degradation on GMC Terrain and Saab 9-5
• Improves heat dissipation to reduce brake fade during extended driving

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 27.00 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Use proper torque specifications for the 5 lug bolts on the 120.00 mm bolt circle. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Verify compatibility with your specific vehicle model and year prior to installation.
