Detailed Product Description

This Power Stop rotor features a vented design that improves heat dissipation during braking, helping to reduce brake fade and maintain consistent performance. The rotor measures 13 inches (330 mm) in outside diameter with an overall height of 55.00 mm, ensuring proper fitment and clearance for the front brake assembly on compatible vehicles. The nominal thickness is 30.00 mm, with a discard thickness of 28.00 mm, indicating when the rotor should be replaced to maintain safe braking.

The Geomet coating applied to the rotor surface provides a protective barrier against rust and corrosion, which is especially beneficial for vehicles exposed to moisture and road salt. This coating helps preserve the rotor’s structural integrity and appearance over time.
