Detailed Rotor Specifications and Features

This Power Stop rotor is a vented type, which means it has internal vanes that allow air to flow through the rotor, helping to dissipate heat more effectively during braking. The rotor measures 321.20 mm (12.60 inches) in outside diameter and has an overall height of 45.90 mm (1.80 inches). It maintains a nominal thickness of 28.10 mm (1.11 inches) and should be replaced once it reaches the discard thickness of 26.00 mm. The rotor is designed with a 5-lug pattern and a mounting bolt hole circle diameter of 115.00 mm, ensuring proper fitment on compatible vehicles.

The Geomet coating applied to this rotor provides a protective layer that resists rust and corrosion, extending the rotor's service life and maintaining braking efficiency in various weather conditions. This coating is especially beneficial for vehicles exposed to road salt or moisture.
