Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a vented rotor type to improve airflow and reduce heat buildup during braking. The directional surface features both drilled holes and slots, which help to evacuate gases, dust, and water, improving brake pad contact and overall stopping power. The rotor’s nominal thickness is 28 mm, with a discard thickness of 26 mm, ensuring safe replacement intervals. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s service life. The rotor’s 5-bolt hole pattern with a 114.3 mm bolt circle diameter matches the factory specifications for the specified Mazda models.

About the 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 corrosion-resistant finish. This product line is designed to offer improved heat dissipation and braking consistency for vehicles requiring reliable performance under various driving conditions. The silver zinc coating on the rotor hat enhances rust resistance, making it suitable for environments prone to moisture and road salt.

Applications and Problem Solving

• Reduces brake fade caused by heat buildup during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation for cleaner rotor and pad contact
• Prevents rust and corrosion on the rotor hat for longer service life
• Maintains proper rotor thickness for safe and effective braking performance

Installation Notes and Tips

Ensure the rotor is installed on compatible Mazda 6, CX-5, or CX-9 models with the correct 5-lug bolt pattern and 114.3 mm bolt circle diameter. Verify rotor thickness before installation and replace if below the discard thickness of 26 mm. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Follow manufacturer torque specifications for lug nuts to avoid rotor warping.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant zinc silver finish on the rotor hat helps maintain durability in corrosive environments. While no specific warranty information is provided, adherence to discard thickness and proper installation ensures optimal rotor lifespan and performance.
