Product Line Details

The Power Stop - Rear Genuine Geomet High Carbon Coated Rotor line focuses on delivering rotors with high carbon cast iron material and a Geomet coating that resists rust and corrosion. This product line is designed to maintain rotor integrity and performance over time, especially in demanding driving conditions. The vented and X-drilled design enhances heat dissipation and braking consistency, making it suitable for Porsche 718 Boxster and Cayman rear brake applications.

Technical Description and Benefits

This disc brake rotor is constructed from high carbon cast iron, which offers improved thermal conductivity and resistance to cracking compared to standard cast iron rotors. The vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The X-drilled surface further aids in dispersing water and debris, helping maintain consistent braking performance in various conditions. The Geomet coating provides a protective layer against rust, extending the rotor's service life. With precise dimensions including an outside diameter of 11.80 inches and a mounting bolt hole circle diameter of 130 mm, this rotor is engineered for exact fitment on compatible Porsche models.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on Porsche 718 Boxster and Cayman
• Addresses brake fade caused by excessive heat during spirited driving
• Prevents rust and corrosion buildup on rear rotors in humid or wet environments
• Improves braking consistency and pedal feel for enhanced vehicle control
• Restores proper rotor thickness and surface condition for safe braking

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 0.71 inches before installation. Clean the mounting surface and hub to remove any rust or debris for proper rotor seating. Use the correct torque specifications for the 5 lug bolts on the 130 mm bolt circle diameter. It is recommended to replace brake pads when installing new rotors to optimize braking performance. Verify compatibility with Porsche 718 Boxster, 718 Cayman, Boxster, and Cayman rear brake assemblies prior to installation.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The high carbon cast iron material and Geomet coating contribute to long-lasting performance and corrosion resistance. While no specific warranty information is provided, Power Stop products are known for consistent quality and reliability in automotive braking applications.
