About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide enhanced braking performance through its vented rotor design and directional surface pattern. The drilled and slotted features help maintain clean rotor surfaces by channeling away dust and gases, which is critical for vehicles like the Oldsmobile Cutlass Supreme and Pontiac Grand Prix that demand consistent stopping power under varied driving conditions.

Product Details and Specifications

This disc brake rotor features a plain disc finish paired with a zinc silver coated hat to resist rust and extend service life. The rotor’s vented design promotes airflow, reducing heat buildup during braking. With a 280 mm outside diameter and 118.1 mm overall height, it fits a variety of GM models including the Chevrolet Impala, Buick Century, and Pontiac GTO. The rotor’s directional drilled and slotted surface improves pad bite and helps prevent brake fade by efficiently dissipating heat and debris.

Applications and Problem Solving

• Restores braking performance on Buick, Cadillac, Chevrolet, Oldsmobile, and Pontiac vehicles
• Reduces brake fade caused by overheating during aggressive or prolonged braking
• Minimizes rotor surface corrosion with rust-resistant coating
• Improves braking consistency by maintaining clean rotor surfaces
• Addresses vibration and noise issues related to worn or warped rotors

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24.51 mm before installation. Properly torque the five 7/16-20 lug bolts to the manufacturer’s specifications. Clean the rotor surface to remove any protective coating before mounting brake pads. This rotor is directional; install with the correct rotation direction for optimal performance. Compatible with vehicles requiring a 280 mm diameter rotor and 120.6 mm bolt circle diameter.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver hat finish extends rotor life by protecting against corrosion. While no specific warranty information is provided, Dynamite Friction products are engineered for reliable, consistent braking performance on compatible GM vehicles.
