About the Power Stop - Rear Genuine Geomet High Carbon Coated Rotor Line

This Power Stop product line focuses on rear rotors that combine high carbon steel with a Geomet coating, which is a zinc-based rust-resistant finish. This coating helps protect the rotor surface from corrosion and extends the service life, especially in environments prone to moisture and road salt. The high carbon content improves rotor durability and reduces the risk of cracking under high thermal stress, making it suitable for performance-oriented BMW models like the M2, M3, and M4.

Technical Details and Specifications

The EBR1485EVC rotor is a vented type, which means it has internal vanes that allow air to flow through the rotor, enhancing heat dissipation during braking. This helps prevent brake fade and maintains consistent braking performance. The rotor’s nominal thickness is 0.94 inches (23.90 mm), with a discard thickness of 0.88 inches (22.40 mm), indicating when the rotor should be replaced to maintain safety and performance. The overall height measures 2.60 inches (64.70 mm), and the outside diameter is 14.60 inches (369.90 mm), matching the OEM specifications for the rear brakes on compatible BMW models. The mounting bolt hole circle diameter is 120 mm with 5 lug holes, ensuring proper fitment and secure installation.

Common Applications and Problem Solving

• Replacement for worn or warped rear rotors on BMW M2, M3, and M4
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps reduce rust and corrosion buildup on rear rotors
• Improves heat management to prevent brake fade during spirited driving
• Restores braking performance to factory specifications

Installation Notes and Tips

Ensure the rotor is compatible with your specific BMW model and rear brake assembly before installation. Clean the hub surface thoroughly to remove rust or debris to ensure proper rotor seating. Torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to optimize braking performance and rotor longevity.

Quality Assurance and Warranty

Power Stop rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The Geomet coating provides enhanced corrosion resistance, contributing to longer rotor life. While specific warranty details are not provided here, Power Stop products typically come with a limited warranty against defects in materials and workmanship.
