Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize braking efficiency. This design helps reduce brake fade by allowing gases and heat to escape more effectively, while the zinc silver hat finish provides corrosion resistance to extend rotor life. This product line is tailored for drivers seeking a balance between performance and durability in their braking components.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal channels to improve airflow and heat dissipation during braking. The rotor’s directional surface is both drilled and slotted, enhancing pad bite and helping to clear water, dust, and brake debris from the contact surface. The rotor measures 280 mm in outside diameter and 47 mm in height, with a nominal thickness of 24 mm and a discard thickness of 23 mm, ensuring it meets precise fitment and safety standards. The zinc silver hat finish and rust-resistant coating protect against corrosion, which is critical for maintaining rotor integrity over time. The rotor features five bolt holes with a diameter of 14.2 mm and a bolt circle diameter of 110 mm, matching the factory specifications for Chevrolet Cobalt and Pontiac G5 models.

Applications and Problem Solving

• Replacement for worn or warped rotors on Chevrolet Cobalt and Pontiac G5
• Improves braking performance by reducing heat buildup and brake fade
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Prevents rust and corrosion that can compromise rotor lifespan
• Maintains consistent braking under wet or dusty conditions with slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 110 mm bolt circle diameter and 14.2 mm bolt hole diameter. Proper torque specifications should be followed to avoid rotor warping. This rotor is directional, so confirm the correct orientation during installation to maintain optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Chevrolet Cobalt and Pontiac G5 vehicles. The rust-resistant coating and zinc silver hat finish contribute to long-term durability. While no specific warranty information is provided, the product is designed for consistent, reliable braking performance when installed and maintained according to manufacturer guidelines.
