DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface technology to improve braking efficiency. The combination of drilled holes and slots on a vented rotor surface helps maintain cooler operating temperatures and reduces brake fade. This product line is tailored for vehicles requiring robust braking solutions under demanding conditions, such as heavy-duty Chevrolet and GMC trucks and vans.

Detailed Product Specifications

This disc brake rotor features a nominal thickness of 38 mm and a discard thickness of 36.5 mm, ensuring a long service life before replacement is necessary. The rotor has an outside diameter of 325 mm and an overall height of 89.3 mm, matching OEM dimensions for proper fitment. The rotor's surface is directional, with drilled and slotted patterns designed to channel away gases and debris, improving pad contact and braking consistency. The rotor is vented to enhance heat dissipation, reducing the risk of warping under heavy braking. The hat section is finished in Geospec silver grey, providing corrosion resistance, while the entire rotor is coated with a rust-resistant layer to protect against environmental damage. Bolt hole and stud/lug hole diameters are precisely 16.4 mm, with eight holes arranged on a 165.1 mm bolt circle diameter, ensuring compatibility with specified Chevrolet and GMC models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Silverado 2500 HD and GMC Sierra 3500 HD
• Improves braking performance in heavy-duty use cases such as towing and hauling
• Reduces brake fade caused by excessive heat buildup during prolonged braking
• Addresses rotor corrosion issues with rust-resistant coating and Geospec finish
• Enhances brake pad bite and debris removal with drilled and slotted surface design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 36.5 mm before installation. The rotor is directional; install with the correct orientation to maintain optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 165.1 mm bolt circle diameter and 16.4 mm hole diameters. Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for the 8 lug nuts to avoid rotor warping.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and Geospec silver grey finish provide added durability against corrosion. While no specific warranty information is provided, the product is designed for reliable performance in heavy-duty Chevrolet and GMC applications.
