Detailed Product Features and Specifications

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is designed with a vented rotor type to improve airflow and reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The directional surface design ensures proper rotation for optimal performance.

The rotor measures 296 mm in outside diameter with a height of 51.8 mm, fitting precisely on Mazda 6 and CX-5 models. It features a nominal thickness of 28 mm and a discard thickness of 26 mm, indicating when the rotor should be replaced to maintain safe braking. The zinc silver hat finish provides corrosion resistance, complemented by a rust-resistant coating on the rotor surface to extend service life.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a vented design. This combination is intended to improve heat dissipation and maintain braking efficiency under demanding conditions. The silver zinc coating on the hat and rust-resistant treatment on the disc surface help protect against corrosion, making these rotors suitable for daily driving and moderate performance use.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mazda 6 and CX-5
• Improves heat dissipation to reduce brake fade during extended braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Restores proper braking surface for improved stopping power and safety

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify the bolt hole pattern matches the vehicle’s hub (5 lug holes, 114.3 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 28 mm. Replace rotors when thickness reaches the discard thickness of 26 mm. Clean the rotor surface of any protective coatings or oils before mounting brake pads.

Quality Assurance

Dynamite Friction manufactures the 631-80080L rotor to meet OEM specifications for Mazda 6 and CX-5 models. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and braking performance within specified thickness limits.
