About the DFC Hi-Carbon Alloy GEOMET Coated Rotor Line

The DFC Hi-Carbon Alloy GEOMET Coated Rotor line by Dynamite Friction features rotors manufactured with a high-carbon alloy for enhanced wear resistance and thermal stability. The GEOMET coating provides corrosion protection, extending rotor life and maintaining performance under various driving conditions. This product line is designed to meet the specific braking needs of performance-oriented vehicles like the Subaru WRX and WRX STI.

Product Details and Specifications

This disc brake rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during aggressive driving or extended use. The nominal thickness of 20 mm ensures structural integrity, while the discard thickness of 18 mm indicates when the rotor should be replaced to maintain safe braking performance. The rotor features five bolt holes with a diameter of 12.8 mm, matching the bolt pattern of Subaru Impreza, WRX, and WRX STI models. With an outside diameter of 316 mm and an inside diameter of 58 mm, this rotor fits precisely within the brake assembly. The height of 63.5 mm is designed to accommodate the caliper and hub assembly of these vehicles.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors on Subaru Impreza, WRX, and WRX STI
• Improves braking consistency and reduces brake noise
• Addresses rotor corrosion and surface rust with GEOMET coating
• Helps prevent brake fade during high-performance or spirited driving
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the bolt hole pattern and rotor dimensions match your Subaru model. Use a calibrated torque wrench to tighten bolts to manufacturer specifications. It is recommended to replace brake pads when installing new rotors to optimize braking performance. Check rotor thickness regularly and replace when reaching discard thickness of 18 mm.
