About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced surface designs that improve braking performance and heat dissipation. This product line features rotors with directional drilled and slotted surfaces, vented construction, and rust-resistant coatings, making them suitable for vehicles like the Toyota 4Runner and Tacoma that require dependable stopping power under various driving conditions.

Product Details and Specifications

This disc brake rotor features a vented design that helps maintain optimal operating temperatures by allowing air to flow through the rotor, reducing the risk of brake fade during extended use. The directional drilled and slotted surface improves pad bite and helps evacuate gases, dust, and water from the braking surface. The rotor’s nominal thickness is 21.7 mm, with a discard thickness of 20 mm, ensuring a long service life before replacement is necessary. The rotor’s hat is finished in Geospec silver grey, providing corrosion resistance and a clean appearance. Additionally, the rotor includes a rust-resistant coating on the disc finish to further protect against environmental wear.

Common Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Toyota 4Runner and Tacoma
• Improves braking performance in wet or dusty conditions with slotted and drilled surface
• Reduces brake fade during heavy braking or towing situations
• Prevents rust and corrosion for longer rotor life
• Restores proper rotor thickness and surface condition for smooth braking

Installation Notes and Tips

Ensure the rotor is compatible with your specific Toyota 4Runner or Tacoma model year before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the 6 bolt holes (bolt circle diameter 139.7 mm) to secure the rotor. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance. Check rotor thickness regularly and replace when thickness reaches the discard limit of 20 mm.
