About the DFC Brake Rotor - Drilled and Slotted - Silver Line
The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on delivering rotors that combine drilled holes and slots to enhance braking efficiency. This design helps reduce brake fade by improving heat dissipation and allows for better removal of brake dust and gases. The zinc silver hat finish adds a layer of rust resistance, making these rotors suitable for long-term use on Infiniti FX and QX models.
Technical Details and Specifications
This disc brake rotor features a vented design that promotes airflow between the rotor surfaces, reducing heat buildup during braking. The rotor’s 320 mm outside diameter and 49.2 mm height ensure proper fitment and compatibility with the specified Infiniti models. The 5-lug bolt pattern with a 114.3 mm bolt circle diameter and 12.7 mm stud hole diameter matches factory specifications for secure installation. The directional slotted and drilled surface improves braking performance in wet and dry conditions by channeling water and debris away from the contact surface.
Applications and Problem Solving
- Compatible with Infiniti FX35, FX37, FX45, and QX70 models requiring replacement rotors
- Addresses brake fade caused by excessive heat during aggressive driving or towing
- Helps reduce brake dust accumulation for cleaner braking surfaces
- Improves wet weather braking performance by evacuating water from the rotor surface
- Prevents rust and corrosion with zinc silver hat finish and rust-resistant coating
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 32 mm before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify bolt hole alignment with the 5-lug 114.3 mm bolt circle diameter pattern on your Infiniti FX or QX model. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
