DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface features to improve braking efficiency and thermal performance. The drilled and slotted design helps evacuate gases and debris from the braking surface, reducing brake fade and maintaining consistent friction. This rotor line is engineered to meet the demands of daily driving and moderate performance applications on compatible Buick, Chevrolet, and GMC vehicles.

Technical Specifications and Features

This Dynamite Friction rotor is a solid disc type with a plain disc finish and a Geospec silver grey hat finish that provides rust resistance. The rotor measures 288 mm in outside diameter and 46.7 mm in overall height. It features a directional surface type with both drilled holes and slots to optimize heat dissipation and pad cleaning. The rotor includes five bolt holes, each 14 mm in diameter, arranged on a 115 mm bolt circle diameter, ensuring proper fitment on specified vehicles. The nominal thickness is 12 mm, with a discard thickness of 10 mm, indicating when replacement is necessary to maintain safe braking performance.

Applications and Problem Solving

• Restores braking performance on Buick Envision, LaCrosse, Regal Sportback, and Regal TourX
• Improves heat dissipation and reduces brake fade on Chevrolet Envista, Equinox, Malibu
• Addresses rotor wear and scoring issues on GMC Terrain and Trax
• Enhances braking consistency with directional drilled and slotted design
• Protects against rust and corrosion for extended rotor life

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 5-lug, 115 mm bolt circle pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 10 mm. Clean the rotor surface to remove any protective coatings or contaminants before mounting brake pads. Proper torque specifications should be followed for all lug nuts to maintain safety and rotor integrity.
