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 daily driving and moderate performance needs, making it suitable for vehicles such as the Chevrolet Malibu and GMC Terrain.

Technical Specifications and Features

This rotor features a vented design with an overall height of approximately 45.77 mm and a nominal thickness of 26 mm, ensuring effective heat dissipation during braking. The drilled and slotted surface improves water and gas evacuation, reducing brake fade. The rotor’s directional surface is engineered to optimize braking efficiency and pad contact. The zinc silver hat finish offers rust resistance, helping maintain structural integrity over time. Bolt hole and stud hole diameters are both 14.2 mm, with a bolt circle diameter of 115 mm, compatible with 5-lug wheel configurations.

Applications and Problem Solving

• Replacement for worn or warped rotors on Buick Encore GX and Chevrolet Trailblazer
• Improves braking performance by reducing heat-related fade in GMC Envista
• Addresses rotor corrosion issues with rust-resistant coating on Buick Regal Sportback
• Enhances brake pad bite and water dispersion for Chevrolet Volt in wet conditions
• Restores braking consistency on GMC Terrain and Chevrolet Trax

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify bolt hole alignment with the vehicle’s hub using the 5-lug, 115 mm bolt circle pattern. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Torque lug nuts to manufacturer specifications and check rotor thickness regularly to avoid disc discard below 23 mm.
