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 slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade under demanding conditions, making it suitable for Toyota trucks and SUVs that require reliable braking performance during off-road or heavy-duty use. The rust resistant coating and Geospec silver grey hat finish contribute to corrosion resistance and long-term rotor integrity.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor surfaces, which helps maintain lower operating temperatures. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, ensuring a clear service limit for safe operation. The directional slotted and drilled surface enhances water and debris evacuation while improving pad cleaning and bite. The rotor measures 319 mm in outside diameter and 67.5 mm in overall height, with a center hole diameter of 108 mm. It features six bolt holes with a 139.7 mm bolt circle diameter and 14.5 mm stud hole diameter, matching the factory specifications for the listed Toyota models.

Applications and Problem Solving

• Improves braking performance on Toyota 4Runner, FJ Cruiser, Hilux, and Tacoma
• Reduces brake fade during heavy braking or off-road conditions
• Helps prevent rotor warping by enhancing heat dissipation
• Minimizes rust and corrosion with protective coating
• Maintains consistent brake pad contact with directional slotted and drilled design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the rotor thickness is above the discard thickness of 26 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Use proper torque specifications for the 6 bolt holes to secure the rotor firmly. This rotor is designed to fit specific Toyota models, so confirm compatibility with your vehicle’s year and trim.
