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 zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of performance-oriented vehicles like the Nissan 300ZX, offering a balance of durability and effective braking under various driving conditions.

Technical Description and Specifications

This disc brake rotor is vented to allow air circulation between the rotor surfaces, which helps dissipate heat generated during braking. The rotor’s surface is both drilled and slotted, which aids in removing brake dust, gases, and water from the contact area, improving braking consistency. The rotor has a nominal thickness of 20 mm and a discard thickness of 18 mm, indicating when replacement is necessary to maintain safety. The hat section features a zinc silver finish that resists rust and corrosion, important for longevity. The rotor includes five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 68 mm, ensuring proper fitment on the Nissan 300ZX hub assembly.

Applications and Problem Solving

• Replacement for worn or warped rotors on Nissan 300ZX
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Supports directional braking surface for optimized pad contact and 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 debris prior to mounting. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter on the Nissan 300ZX hub. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed following the indicated rotation direction for optimal performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Nissan 300ZX vehicles. The rust-resistant zinc silver hat finish enhances durability against corrosion. While no specific warranty information is provided, the rotor’s design and materials support reliable braking performance when installed and maintained properly.
