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 with a vented design to optimize brake cooling and debris removal. This product line is tailored to provide consistent braking performance and durability for vehicles like the Ford Bronco and Ranger, where heat management and rotor longevity are critical.

Detailed Product Description

This disc brake rotor is constructed with a vented design to allow air circulation between the rotor surfaces, reducing heat buildup during braking. The directional slotted and drilled surface helps evacuate gases, dust, and water, improving brake pad contact and reducing fade. The rotor’s nominal thickness is 34 mm, with a discard thickness of 32 mm, ensuring a clear service life indicator. The rotor features a plain disc finish and a Geospec silver grey hat finish that includes a rust resistant coating to protect against corrosion. With six bolt holes measuring 13.2 mm in diameter and a bolt circle diameter of 139.7 mm, this rotor fits securely on compatible Ford models. The 311 mm outside diameter and 66.35 mm height are designed to meet OEM specifications for proper fitment and performance.

Applications and Problem Solving

• Replaces worn or warped rotors on Ford Bronco and Ranger models
• Improves brake cooling to reduce fade during heavy braking
• Helps prevent rust and corrosion with protective coating
• Enhances braking performance in wet or dusty conditions with slotted and drilled surface
• Maintains proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor is compatible with your specific Ford Bronco or Ranger model before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Torque all bolts to manufacturer specifications using the six bolt holes provided. Inspect brake pads for wear and replace if necessary to maximize rotor performance. Follow all safety procedures when working on the braking system.
