PowerStop JBR1366EVC Disc Brake Rotor - Rear

Power Stop Rear Genuine Geomet Coated Rotor Overview

The Power Stop - Rear Genuine Geomet Coated Rotor (Part Number JBR1366EVC) is engineered for reliable braking performance on Subaru Impreza, WRX, and WRX STI models. Designed with a rust-resistant Geomet coating and vented construction, this rotor supports consistent heat dissipation and long-term durability.

• Compatible with Subaru Impreza, WRX, and WRX STI rear disc brake systems
• Vented disc brake rotor design for improved cooling
• Rust resistant Geomet coating to reduce corrosion
• Nominal thickness of 0.79 inches (20.00 mm) with discard thickness at 0.71 inches (18.00 mm)
• Overall height of 2.50 inches (63.40 mm) and outside diameter of 12.40 inches (316.00 mm)
• Mounting bolt hole circle diameter of 4.50 inches (114.30 mm) with 5 lug holes

Detailed Product Description

This Power Stop rotor is part of the Rear Genuine Geomet Coated Rotor line, which focuses on providing rotors with a factory-style Geomet coating for enhanced corrosion resistance. The vented rotor design helps maintain optimal braking temperatures by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. With precise dimensions including a nominal thickness of 0.79 inches and a discard thickness of 0.71 inches, this rotor meets OEM specifications for Subaru Impreza, WRX, and WRX STI rear brake systems. The 5-lug mounting pattern with a 4.50-inch bolt circle diameter ensures proper fitment and secure installation.

Applications and Problem Solving

• Replacement for worn or warped rear rotors on Subaru Impreza, WRX, and WRX STI
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps prevent rust and corrosion-related rotor degradation
• Improves heat dissipation to reduce brake fade during aggressive driving
• Restores braking performance to factory specifications

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the rotor thickness is within the discard limits (minimum 0.71 inches) to maintain safe braking performance. Use proper torque specifications for the 5-lug mounting bolts to avoid rotor warping. It is recommended to inspect brake pads and replace them if worn when installing new rotors.

Quality Assurance

Power Stop rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The Geomet coating provides enhanced rust resistance to extend rotor life. While specific warranty details are not provided, Power Stop products are known for consistent quality and durability in automotive braking applications.
