Product Line Details: Power Stop - Front Genuine Geomet Coated Rotor

This rotor is part of the Power Stop - Front Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating. This coating enhances rust resistance without compromising braking performance, making it suitable for drivers who require reliable stopping power and rotor longevity. The vented design helps dissipate heat effectively, reducing the risk of brake fade during extended use.

Technical Specifications and Features

The JBR1147EVC rotor features a vented design that improves airflow and cooling, essential for maintaining brake efficiency under demanding conditions. Its nominal thickness of 32.00 mm ensures structural integrity, while the discard thickness of 30.00 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s outside diameter measures 295.80 mm, matching OEM specifications for the Lexus GS300 and IS250 front brakes. The Geomet coating provides a protective layer against rust and corrosion, extending the rotor’s service life in various driving environments.

Applications and Problem Solving

• Replacement for worn or warped front rotors on Lexus GS300 and IS250
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust buildup that can reduce braking efficiency
