DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and precision slots to optimize braking efficiency. This design helps channel away gases, dust, and water from the rotor surface, improving pad contact and reducing the risk of brake fade. The directional surface pattern further enhances performance by ensuring consistent braking force and heat dissipation, making it suitable for both daily driving and more demanding conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor faces, which helps maintain lower operating temperatures during braking. The rotor’s nominal thickness is 32 mm, with a discard thickness of 30.5 mm, indicating when replacement is necessary to maintain safe braking performance. The rotor features a plain disc finish and a Geospec silver grey finish on the hat, which provides rust resistance and durability. The bolt hole diameter and stud/lug hole diameter are both 17 mm, with five holes arranged on a 127 mm bolt circle diameter, ensuring proper fitment on compatible vehicles.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Dodge Durango and Jeep Grand Cherokee models
• Improves heat dissipation to reduce brake fade during heavy braking or towing
• Slotted and drilled design helps maintain consistent braking performance in wet or dusty conditions
• Rust resistant coating protects against corrosion for longer rotor life
• Directional surface pattern enhances brake pad contact and reduces noise

Installation Notes and Tips

Ensure the rotor is compatible with your specific Dodge Durango or Jeep Grand Cherokee model before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications for the five 17 mm bolt holes to secure the rotor. Since this rotor features a directional surface, install it according to the indicated rotation direction for optimal performance. Check rotor thickness regularly and replace when it reaches the discard thickness of 30.5 mm.
