Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented Nissan 240SX drivers who require consistent braking under varied driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation, reducing the risk of brake fade during extended use. The rotor’s surface is both drilled and slotted, which helps evacuate gases, dust, and water from the braking surface, improving pad contact and braking efficiency. The rotor has a nominal thickness of 20 mm and a discard thickness of 18 mm, ensuring safe replacement intervals. The zinc silver hat finish offers rust resistance, protecting the rotor’s structural integrity over time. With 5 bolt holes and a bolt circle diameter of 114.3 mm, this rotor fits securely on the Nissan 240SX hub assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan 240SX
• Improves braking performance in wet or dusty conditions
• Reduces brake fade during aggressive or extended driving
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances heat dissipation to prevent premature brake component wear

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the Nissan 240SX hub and torque lug nuts to manufacturer specifications. Directional rotors must be installed with the correct rotation direction for optimal performance. It is recommended to replace brake pads when installing new rotors to maintain consistent braking.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant zinc silver finish helps extend rotor life by preventing corrosion. While specific warranty details are not provided, Dynamite Friction products typically adhere to quality control processes to ensure reliable fitment and function for Nissan 240SX applications.
