About the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to enhance braking efficiency. This design helps reduce brake fade by allowing heat and gases to escape more effectively during braking. The silver zinc coating on the hat area provides corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Detailed Product Description

This disc brake rotor is specifically designed for the Nissan 240SX, ensuring precise fitment and reliable braking performance. The solid rotor construction provides structural integrity, while the drilled and slotted surface improves pad bite and helps maintain consistent friction under demanding conditions. The rotor’s nominal thickness of 9 mm and discard thickness of 8 mm indicate the usable lifespan before replacement is necessary. The zinc silver hat finish offers protection against rust, which is critical for maintaining rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan 240SX models
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps prevent brake pad glazing by maintaining a clean rotor surface
• Addresses corrosion issues with rust-resistant coating
• Restores braking performance and pedal feel

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness meets the minimum discard thickness of 8 mm to maintain safety and performance. Use proper torque specifications for the 4-bolt mounting pattern with a 114.3 mm bolt circle diameter. It is recommended to inspect brake pads and hardware during rotor replacement to ensure optimal braking system function.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for the Nissan 240SX. The rust-resistant zinc silver finish and precise machining contribute to long-lasting performance. While no specific warranty information is provided, the rotor is designed to maintain structural integrity and consistent braking under normal operating conditions.
