Detailed Product Features and Specifications

This Dynamite Friction rotor features a directional surface that is both drilled and slotted, allowing for efficient removal of brake dust, gases, and water, which helps maintain consistent braking performance. The vented rotor design improves airflow to reduce heat buildup during heavy braking, minimizing the risk of brake fade. The zinc black coating on the rotor hat provides corrosion resistance, extending the rotor's service life. With a nominal thickness of 30 mm and a discard thickness of 27 mm, this rotor meets precise wear limits to ensure safety and reliability. The rotor's 345 mm outside diameter and 45.5 mm height are engineered to exact OEM specifications for a proper fit on the Buick ELR and Cadillac Regal Sportback.

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

The DFC Brake Rotor - Drilled and Slotted - Black product line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant black zinc finish. This line is designed to provide enhanced braking performance and durability, particularly for vehicles requiring directional rotors with vented designs. The black zinc hat finish offers additional protection against rust, making these rotors suitable for various driving conditions.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains consistent braking performance on Buick ELR and Cadillac Regal Sportback

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 27 mm to maintain safety standards. Use the correct torque specifications for the five 14 mm bolt holes with a 115 mm bolt circle diameter. Directional rotors must be installed with the correct rotation direction to ensure optimal performance and longevity.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM standards for fit, form, and function.
