Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on providing rotors with enhanced cooling and braking efficiency through a combination of drilled holes and precision slots. The vented design improves airflow to reduce heat buildup during braking, which helps prevent brake fade under demanding conditions. The rotor’s directional surface pattern is engineered to channel gases and debris away from the contact area, maintaining consistent pad contact and braking response.

The rotor’s nominal thickness is 34 mm, with a discard thickness of 31.6 mm, ensuring a durable lifespan while meeting safety standards. The zinc silver coating on the hat offers corrosion resistance, extending the rotor’s service life in various driving environments. With 5 bolt holes sized at 15.8 mm diameter and a bolt circle diameter of 114.3 mm, this rotor is designed to fit securely on the Ford Mustang’s hub assembly.

Applications and Problem Solving

• Replacement for worn or warped rotors on Ford Mustang models
• Improves heat dissipation to reduce brake fade during aggressive driving
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Helps maintain consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion buildup on rotor hats for longer durability

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the rotor thickness is within specifications before mounting. Use proper torque settings on the 5 lug bolts to secure the rotor. The directional surface requires installation in the correct rotation direction for optimal performance. It is recommended to replace brake pads simultaneously to ensure even wear and braking efficiency.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Ford Mustang vehicles. The rust-resistant coating and vented design contribute to long-term durability and consistent braking performance.
