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 on the braking surface. This design helps to reduce brake fade by allowing gases and debris to escape, while the vented rotor construction improves heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is tailored for drivers seeking reliable, performance-oriented rotors compatible with specific vehicle applications such as the Nissan 300ZX.

Technical Specifications and Features

This disc brake rotor is vented, which means it has internal vanes between the two braking surfaces to improve airflow and cooling during operation. The rotor’s surface is both drilled and slotted in a directional pattern, enhancing water and dust evacuation and maintaining consistent pad contact. The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, ensuring safe replacement intervals. The hat section is finished in zinc silver with a rust-resistant coating to protect against corrosion. It features four bolt holes with a bolt circle diameter of 103 mm and a center hole diameter of 81 mm, designed to fit the Nissan 300ZX precisely.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan 300ZX
• Improves braking performance under high heat conditions
• Reduces brake fade during aggressive driving or towing
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad bite and reduces noise with slotted and drilled design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coating or residue before mounting. Verify bolt hole alignment with the Nissan 300ZX hub using the 103 mm bolt circle diameter and 4-lug pattern. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on the Nissan 300ZX. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance.
