Detailed Product Features and Specifications
The DFC Brake Rotor - Drilled and Slotted - Black is part of Dynamite Friction's DFC product line, which focuses on delivering rotors with enhanced surface designs for improved braking efficiency. This rotor combines drilled holes and precision slots arranged directionally to help evacuate gases, dust, and water from the braking surface, reducing brake fade and maintaining consistent stopping power. The vented rotor construction further aids in heat dissipation, which is critical for maintaining rotor integrity and brake performance during extended use.
With a nominal thickness of 20 mm and a discard thickness of 18 mm, this rotor provides a balance between durability and performance. The zinc black coating on the hat area offers rust resistance, extending the rotor's service life. The rotor's 5-lug bolt pattern with a 110 mm bolt circle diameter and 14.2 mm bolt hole diameter ensures precise fitment on Chevrolet Cobalt models. The overall diameter of 292 mm and height of 62.7 mm are designed to match OEM specifications for reliable installation and operation.
Applications and Problem Solving
- Replaces worn or warped rotors on Chevrolet Cobalt vehicles
- Addresses brake fade caused by overheating during aggressive driving or towing
- Improves braking response in wet or dusty conditions through drilled and slotted design
- Reduces rust and corrosion on rotor hats for longer service life
- Restores proper rotor thickness to maintain braking safety and performance
Installation Notes and Tips
Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is within the discard limits before mounting. Use proper torque specifications for the 5-lug bolts to avoid rotor warping. This rotor is directional; install it according to the indicated rotation direction for optimal performance.
