Details on the DFC Geoperformance Rotor - Drilled and Slotted 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. This configuration helps reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The directional surface pattern is optimized for specific rotation direction, enhancing braking efficiency and rotor longevity. This rotor line is suitable for heavy-duty applications, such as those found in Ford and Lincoln trucks and SUVs.

Product Specifications and Features

This rotor features a nominal thickness of 34 mm and a discard thickness of 32 mm, ensuring a long service life before replacement is necessary. The 350 mm outside diameter and 49.5 mm overall height provide a substantial braking surface area. The rotor is vented to allow airflow between the rotor faces, reducing heat buildup during heavy braking. The drilled and slotted surface improves pad bite and helps clear water and brake dust. The rust resistant coating and Geospec silver grey hat finish protect against corrosion, maintaining rotor integrity over time.

Compatible Vehicles and Applications

• Ford F-150
• Ford Expedition
• Lincoln Navigator
• Lincoln Mark LT

This rotor is designed for use in disc brake systems on these specific models, providing reliable stopping power for daily driving and towing applications.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup
• Reduced braking performance due to rotor warping
• Corrosion and rust on rotor surfaces
• Brake noise and vibration from uneven rotor wear
• Decreased pad bite in wet or dusty conditions

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation direction. Verify that the bolt hole pattern (6 holes, 135 mm bolt circle diameter) matches the hub assembly. Clean the rotor surface before installation to remove any protective coatings or contaminants. Check the nominal and discard thickness to confirm rotor suitability and safety.

Quality Assurance and Warranty

Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and durable finishes contribute to extended rotor life. Warranty details are available from the manufacturer and should be reviewed prior to purchase.
