Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. The black zinc coating on the rotor hat provides corrosion resistance, extending rotor life in various driving conditions. This product line is tailored for drivers seeking enhanced braking control and durability on compatible Nissan and INFINITI models.

Technical Description and Specifications

This disc brake rotor features a vented design that promotes airflow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface pattern helps evacuate brake dust, water, and gases, maintaining consistent friction and reducing brake fade. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, ensuring safe replacement intervals. The zinc black hat finish offers rust resistance, while the plain disc finish maintains a clean braking surface. The rotor is directional, meaning it must be installed in the correct orientation to maximize performance. It includes four bolt holes with a 114.3 mm bolt circle diameter and a center hole diameter of 68 mm, matching the specifications for Nissan 240SX, G20, and Sentra models.

Applications and Problem Solving

• Compatible with Nissan 240SX, G20, and Sentra models requiring vented, drilled, and slotted rotors
• Addresses brake fade caused by excessive heat during aggressive or prolonged braking
• Improves water and debris evacuation for better wet-weather braking performance
• Helps reduce brake dust buildup on pads and rotors
• Provides corrosion resistance to extend rotor service life

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the bolt hole pattern and center hole diameter match the vehicle specifications. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 22 mm and is above the discard thickness of 20 mm. Proper torque specifications should be followed when securing the rotor to avoid warping or uneven wear.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust-resistant zinc black coating on the rotor hat enhances durability against corrosion. While no specific warranty information is provided, adherence to discard thickness and proper installation ensures optimal rotor lifespan and performance on Nissan and INFINITI vehicles.
