DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on rotors that combine drilled holes and precision slots to optimize braking performance. This design helps evacuate gases, dust, and water from the rotor surface, improving pad contact and reducing the risk of brake fade. The vented rotor construction further aids in heat dissipation, making it suitable for vehicles like the Dodge Durango and Jeep Grand Cherokee that may encounter varied driving conditions.

Detailed Product Description

This disc brake rotor features a directional surface with both drilled holes and slots, which work together to maintain consistent braking performance by allowing heat and debris to escape efficiently. The rotor is vented, promoting airflow between the rotor faces to reduce operating temperatures. The rotor’s nominal thickness is 32mm, with a discard thickness of 30.5mm, ensuring a clear maintenance threshold. 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 surface to extend service life. The 5-bolt hole pattern with a 127mm bolt circle diameter and 17mm bolt hole diameter matches the factory specifications for the listed Dodge and Jeep models.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Dodge Durango and Jeep Grand Cherokee
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust resistant coating
• Restores proper rotor thickness and surface condition for safe braking

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (30.5mm) before installation
• Clean rotor surface before mounting to remove any protective coatings or debris
• Verify bolt hole alignment with vehicle hub using the 5-bolt, 127mm bolt circle pattern
• Use proper torque specifications for lug nuts to avoid rotor warping
• Check compatibility with brake pads designed for drilled and slotted rotors
