Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line
The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize brake pad contact and heat dissipation. This product line is designed to provide consistent braking performance while minimizing brake fade, making it suitable for vehicles like the INFINITI J30 and Q45 that require reliable stopping power under various driving conditions.
Technical Specifications and Features
This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat buildup during braking. The rotor’s surface is both drilled and slotted, which helps evacuate gases, dust, and water, improving brake pad bite and overall braking efficiency. The rotor has a nominal thickness of 16 mm and a discard thickness of 14 mm, ensuring safe replacement intervals. The zinc silver coating on the hat provides rust resistance, extending the rotor’s service life. With 5 bolt holes and a bolt circle diameter of 114.3 mm, it fits securely on the specified INFINITI models.
Applications and Problem Solving
- Restores braking performance on INFINITI J30 and Q45 vehicles
- Reduces brake fade caused by overheating during extended use
- Improves water and debris evacuation for consistent braking in wet conditions
- Prevents rust and corrosion on the rotor hat for longer durability
- Maintains proper rotor thickness to ensure safe braking operation
Installation Notes and Tips
Ensure the rotor surface is clean and free of contaminants before installation. Verify the bolt hole pattern matches the vehicle’s hub (5 bolts, 114.3 mm bolt circle diameter). Check the rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 16 mm. Properly torque lug nuts to manufacturer specifications 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 coating and vented design contribute to the rotor’s durability and performance. While no specific warranty information is provided, the product is designed for reliable service on compatible INFINITI J30 and Q45 models.
