Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide enhanced braking efficiency through a combination of drilled holes and slots on the rotor surface. This design improves heat dissipation and helps reduce brake fade during demanding driving conditions. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life. This rotor line is engineered specifically for vehicles requiring vented rotors with directional braking surfaces, such as the Cadillac ATS and CT4.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 26 mm and a discard thickness of 23 mm, ensuring a clear service limit for safe operation. The rotor is vented to allow better airflow and heat management, which is critical for maintaining braking performance under heavy use. The directional slotted and drilled surface improves water and debris evacuation, enhancing braking response in various conditions. The rotor includes five bolt holes with a diameter of 14.2 mm and a bolt circle diameter of 115 mm, matching the factory specifications for Cadillac ATS and CT4 models. The zinc silver finish on the rotor hat provides rust resistance, while the plain disc finish maintains structural integrity.

Applications and Problem Solving

• Replacement for worn or warped rotors on Cadillac ATS and CT4
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or debris-prone environments
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper braking surface for improved pedal feel and stopping power

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 coatings or contaminants prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 115 mm bolt circle pattern. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures the 631-46033R rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant zinc silver coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, this rotor is designed for reliable service life when installed and maintained according to vehicle manufacturer guidelines.
