Detailed Rotor Specifications and Features

This Power Stop rotor features a vented design that helps reduce brake fade by allowing better airflow and heat dissipation during braking. The Geomet coating provides a protective layer against rust and corrosion, which is especially beneficial for vehicles exposed to moisture and road salt. With a nominal thickness of 0.87 inches and a discard thickness of 0.79 inches, this rotor maintains structural integrity and performance throughout its service life. The rotor’s dimensions, including a 10.10-inch outside diameter and 1.90-inch overall height, are tailored to fit the front brake assemblies of Nissan 240SX, Sentra, and Infiniti G20 models precisely.

About the Power Stop - Front Genuine Geomet Coated Rotor Line

The Power Stop - Front Genuine Geomet Coated Rotor product line focuses on providing rotors with a factory-style Geomet coating that enhances corrosion resistance without compromising braking performance. This coating is applied to the rotor surface to protect against rust, which can lead to uneven wear and reduced rotor lifespan. The line is designed to meet or exceed OEM specifications, making it a suitable replacement for front disc brake rotors on compatible Nissan and Infiniti vehicles.

Common Applications and Problem Solving

• Replacement for worn or warped front rotors on Nissan 240SX, Sentra, and Infiniti G20
• Addresses brake noise caused by rust buildup on rotor surfaces
