Power Stop - Front Genuine Geomet High Carbon Coated Rotor Product Line

This rotor is part of the Power Stop - Front Genuine Geomet High Carbon Coated Rotor line, which focuses on delivering rotors with advanced corrosion resistance and improved thermal management. The Geomet coating provides a protective layer that helps extend rotor life by preventing rust, while the high carbon cast iron material enhances braking stability and reduces noise. This product line is designed to meet the specific braking demands of performance vehicles like Porsche models.

Detailed Product Description

The EBR834EVC rotor is constructed from high carbon cast iron, a material known for its ability to withstand high temperatures and resist warping under stress. Its vented design allows air to flow between the rotor surfaces, improving heat dissipation during heavy braking. The X-drilled surface pattern aids in expelling gases and moisture, which can otherwise reduce braking efficiency. The Geomet coating adds a layer of rust resistance, helping maintain rotor integrity and appearance over time. With an overall height of 67.20 mm and a mounting bolt hole circle diameter of 130 mm, this rotor fits securely on the front brake assembly of Porsche 911, Boxster, and Cayman vehicles equipped with 5 lug holes.

Common Applications and Issues Addressed

• Replacement for worn or warped front disc brake rotors on Porsche 911, Boxster, and Cayman
• Improves braking consistency by reducing rotor heat buildup and fade
• Addresses corrosion issues common in high humidity or salted road environments
• Restores proper rotor thickness to maintain safe braking performance
• Helps eliminate brake noise caused by uneven rotor surfaces or rust buildup

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26.00 mm) before installation
• Clean mounting surface and hub to prevent rotor runout
• Torque lug nuts to manufacturer specifications for secure fitment
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Break in new rotors with proper bedding procedure to avoid uneven wear
