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 provide enhanced heat management and improved braking response. The drilled and slotted surface design helps to evacuate gases and debris from the braking surface, reducing brake fade during aggressive driving. The silver zinc coating on the rotor hat offers additional rust resistance, extending the rotor's service life under various driving conditions.

Technical Specifications and Features

This disc brake rotor features a vented design to improve airflow and cooling during braking. The rotor's surface is both drilled and slotted, which aids in maintaining clean pad contact and reducing heat buildup. The rotor is directional, meaning it is designed to rotate in a specific direction to maximize performance. It has a nominal thickness of 24 mm and a discard thickness of 22 mm, ensuring safe replacement intervals. The rotor's overall diameter measures 296 mm, with a height of 49.2 mm and a center hole diameter of 68 mm. It includes 5 bolt holes with a bolt circle diameter of 114.3 mm, matching the lug pattern of compatible vehicles.

Applications and Problem Solving

• Improves braking performance on INFINITI 350Z and Nissan G35 models
• Reduces brake fade during high-temperature conditions
• Helps prevent rust and corrosion with zinc silver hat finish
• Maintains consistent pad contact with slotted and drilled surface
• Supports safe braking by meeting discard thickness specifications

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify that the bolt hole pattern matches the hub assembly (5 bolts, 114.3 mm bolt circle diameter). Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 24 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor with rust-resistant coatings and precise machining to meet OEM standards. While no specific warranty information is provided, adherence to discard thickness and proper installation will help maintain rotor performance and safety over time.
