About the Power Stop - Front Genuine Geomet Coated Rotor Line

The Power Stop - Front Genuine Geomet Coated Rotor line features rotors with a Geomet rust-resistant coating that helps prevent corrosion and extends the service life of the rotor. This coating is applied to the rotor surface to protect against rust buildup, which is especially beneficial in regions with high humidity or road salt exposure. The vented rotor design enhances heat dissipation during braking, reducing the risk of brake fade and maintaining consistent braking performance.

Detailed Product Description

This disc brake rotor is vented to allow better airflow and heat management, which is critical for maintaining braking efficiency under demanding conditions. The rotor measures 10.10 inches (256.00 mm) in outside diameter and has an overall height of 1.60 inches (41.10 mm), ensuring proper fitment and compatibility with the specified Chevrolet and Pontiac models. The nominal thickness of 0.94 inches (23.90 mm) and discard thickness of 0.87 inches (22.00 mm) provide clear service limits for safe rotor replacement. The mounting bolt hole circle diameter is 3.90 inches (100.00 mm) with 4 lug holes, matching factory specifications for secure installation.

Common Applications and Issues Addressed
