About the Power Stop - Genuine Geomet Coated Rotor Line

The Power Stop - Genuine Geomet Coated Rotor line features rotors with a specialized Geomet coating that provides superior rust resistance compared to standard rotors. This coating helps maintain rotor integrity and appearance over time, especially in environments prone to moisture and road salt exposure. The AR85114EVC rotor is part of this line, combining the benefits of vented rotor design with the protective Geomet finish.

Technical Details and Specifications

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The nominal thickness of 39.20 mm ensures durability, while the discard thickness of 37.40 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s overall height is specified as 124.00 mm and 4.90 mm, accommodating specific vehicle fitments. The outside diameter measurements of 389.90 mm and 15.40 mm correspond to the rotor’s size parameters, ensuring compatibility with designated brake systems. The mounting bolt hole circle diameter of 163.00 mm and 6.40 mm, along with 10 stud/lug holes, provide secure attachment to the vehicle hub.

Compatible Vehicles and Applications

• Replacement rotor for vehicles requiring a 10-lug vented disc brake rotor
• Suitable for models that specify a 389.90 mm outside diameter rotor
• Ideal for vehicles needing rust-resistant rotors with Geomet coating
• Compatible with brake systems matching the mounting bolt hole circle diameter of 163.00 mm
• Used in applications where maintaining rotor thickness above 37.40 mm is critical for safety

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 37.40 mm. Proper cleaning of the rotor surface before mounting is recommended to remove any protective coatings or residues. Verify that the mounting bolt hole circle diameter and stud/lug hole quantity match the vehicle specifications. Use appropriate torque settings for lug nuts to avoid rotor warping. It is advisable to inspect brake pads and other related components during rotor replacement for optimal braking performance.
