Detailed Product Features and Specifications
This Dynamite Friction rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and reduces the risk of brake fade. The rotor surface is both drilled and slotted, providing enhanced water and debris evacuation while improving pad bite and overall braking response. The directional surface pattern is engineered to optimize braking efficiency and rotor longevity.
The rotor's nominal thickness is 24.1 mm, with a discard thickness of 22.7 mm, ensuring it meets OEM specifications for safe use and replacement intervals. Measuring 258 mm in outside diameter and 46.9 mm in overall height, it fits vehicles requiring a 5-lug bolt pattern with 14.7 mm diameter holes and a 108 mm bolt circle diameter. The zinc black hat finish and rust-resistant coating protect against corrosion, extending the rotor's service life.
DFC Brake Rotor - Drilled and Slotted - Black Product Line
The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine functional surface treatments with corrosion-resistant finishes. This product line is designed to provide improved braking performance through enhanced heat dissipation and surface friction characteristics, while the black zinc coating on the rotor hat offers additional protection against rust and environmental wear.
Applications and Problem Solving
- Replacement rotor for worn or warped brake rotors on Ford, Lincoln, and Mercury models
- Improves braking performance in wet or debris-prone conditions with drilled and slotted surface
- Reduces brake fade during extended or aggressive braking due to vented design
- Prevents premature rotor corrosion with rust-resistant zinc black coating
- Restores proper rotor thickness and surface integrity for safe braking
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 22.7 mm before installation. Clean the rotor surface to remove any protective coatings or residues that may affect brake pad contact. Verify compatibility with your vehicle’s bolt pattern (5 lug, 14.7 mm diameter, 108 mm bolt circle) and confirm the directional surface orientation during installation for optimal performance. Use proper torque specifications for lug nuts to avoid rotor warping.
Quality Assurance
Dynamite Friction rotors are manufactured to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and zinc black finish contribute to durability and corrosion resistance. While no specific warranty information is provided, adherence to OEM specifications ensures reliable performance when installed and maintained properly.
