About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine vented construction with a directional drilled and slotted surface. This design enhances heat dissipation and helps maintain braking efficiency under demanding conditions. The rust-resistant coating and Geospec silver grey hat finish contribute to durability and corrosion resistance, making these rotors suitable for daily driving and moderate performance needs.

Technical Details and Specifications

This vented disc brake rotor features a nominal thickness of 20 mm and a discard thickness of 18.4 mm, ensuring a clear service life indicator. The rotor’s 331 mm outside diameter and 53.5 mm height are matched to the bolt pattern of 6 holes with a 132 mm bolt circle diameter, compatible with the specified GM vehicles. The drilled and slotted surface is directional, designed to improve water and debris evacuation while reducing brake fade. The rotor’s hat is finished in Geospec silver grey and treated with a rust-resistant coating to extend service life.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Buick Acadia and Acadia Limited
• Improves braking consistency on Chevrolet Traverse and GMC Acadia models
• Helps reduce brake fade and heat buildup during extended braking
• Addresses rotor corrosion issues with rust-resistant coating
• Compatible with Saturn Outlook brake systems requiring 6-lug vented rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18.4 mm before installation. The directional drilled and slotted surface must be installed following the correct rotation direction for optimal performance. Verify bolt hole alignment with the 6-lug 132 mm bolt circle diameter pattern. Clean the rotor surface of any protective coatings before mounting brake pads. Proper torque specifications should be followed to avoid rotor warping.
