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 in a directional pattern. This design improves brake pad cleaning and gas venting, which helps maintain consistent braking performance and reduces the risk of brake fade. The rotors feature a rust resistant coating and a durable Geospec silver grey hat finish, enhancing longevity and resistance to environmental wear.
Technical Details and Specifications
This disc brake rotor features a nominal thickness of 24 mm and a discard thickness of 22 mm, ensuring safe replacement intervals. The rotor’s 308 mm outside diameter and 80.75 mm height are engineered to match the braking system specifications of Ford Bronco and Ranger models. The six bolt holes, each 13.2 mm in diameter, align with a 139.7 mm bolt circle diameter, providing secure mounting. The center hole diameter of 93 mm ensures proper rotor centering on the hub. The rotor’s plain disc finish combined with the directional slotted and drilled surface optimizes heat dissipation and brake pad contact.
Applications and Problem Solving
- Replacement rotor for worn or warped rotors on Ford Bronco and Ranger vehicles
- Improves heat dissipation to reduce brake fade during heavy braking
- Helps maintain consistent braking performance in wet or dusty conditions
- Rust resistant coating addresses corrosion issues common in humid or salty environments
- Directional slotted and drilled design assists in removing brake dust and gases
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 22 mm before installation. Clean the rotor surface to remove any protective coating residue before mounting. Verify bolt hole alignment with the vehicle hub using the 139.7 mm bolt circle diameter and six bolt holes. Proper torque specifications should be followed to avoid rotor warping. This rotor is designed specifically for Ford Bronco and Ranger models; confirm vehicle compatibility prior to installation.
