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 brake pad contact and improve water and gas evacuation. This design helps maintain consistent braking performance under demanding conditions, making it suitable for Toyota 4Runner and Tacoma vehicles requiring reliable stopping power and rotor longevity.

Technical Details and Specifications

This disc brake rotor is vented to allow airflow between the rotor surfaces, which helps dissipate heat generated during braking. The directional slotted and drilled surface improves pad bite and reduces brake fade by channeling away dust, gases, and moisture. The rotor has a nominal thickness of 21.8 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. It features six bolt holes with a bolt circle diameter of 139.7 mm and a center hole diameter of 108.1 mm, designed to fit specific Toyota 4Runner and Tacoma models.

Applications and Problem Solving

• Restores braking performance on Toyota 4Runner and Tacoma vehicles with worn or damaged rotors
• Reduces brake fade during heavy or repeated braking by improving heat dissipation
• Minimizes brake dust and gas buildup for consistent pad contact
• Helps prevent rust and corrosion with a protective coating
• Improves wet weather braking by channeling water away from the rotor surface

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the six bolt holes and 139.7 mm bolt circle diameter. Proper torque specifications should be followed to avoid rotor warping. This rotor is directional; install with the correct orientation for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 830-76123R rotor to meet OEM standards for fit and function on Toyota 4Runner and Tacoma models. The rust resistant coating and precision machining contribute to long service life. Warranty information is available from the manufacturer and should be consulted for coverage details.
