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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented braking while maintaining compatibility with specific vehicle models such as the Buick Cascada and Cadillac ELR.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, which helps prevent brake fade. The rotor’s nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring a clear maintenance threshold. The rotor measures 321 mm in outside diameter and 45.5 mm in overall height, fitting precisely with the specified vehicle models. The rotor surface is both drilled and slotted in a directional pattern, which aids in channeling away gases and debris from the brake pad contact area, improving braking consistency.

Applications and Problem Solving

• Replaces worn or warped rotors on Buick Cascada and Cadillac ELR
• Addresses brake fade caused by excessive heat buildup
• Improves braking response and pad bite with slotted and drilled design
• Prevents rust and corrosion with zinc silver coated rotor hat
• Maintains proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor surface is clean and free of contaminants before installation. Verify the bolt hole pattern matches the vehicle’s hub (5 holes, 14.3 mm diameter, 115 mm bolt circle). Use proper torque specifications for lug nuts to avoid rotor warping. Since this rotor is directional, confirm the correct orientation during installation to maintain optimal braking efficiency.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant coating on the rotor hat helps extend service life under normal driving conditions.
