Detailed Product Description

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver product line, designed to provide enhanced braking efficiency and heat management. The rotor features a vented design that improves airflow to reduce heat buildup during braking. The drilled and slotted surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing brake fade. The zinc silver coating on the hat offers corrosion resistance, extending the rotor's service life.

With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor ensures safe and reliable braking performance throughout its lifespan. The rotor's directional surface pattern is engineered to optimize braking force and maintain smooth operation. Its 4-bolt hole configuration with a 114.3 mm bolt circle diameter matches the Mazda RX-7 specifications for a precise fit.

Applications and Problem Solving

• Replacement rotor for worn or warped Mazda RX-7 brake rotors
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps prevent rust and corrosion with zinc silver hat finish
• Maintains braking performance in wet conditions with drilled and slotted surface
• Restores braking smoothness and reduces noise caused by uneven rotor surfaces

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 debris prior to mounting. Verify bolt hole alignment with the Mazda RX-7 hub using the 4-bolt pattern and 114.3 mm bolt circle diameter. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for the Mazda RX-7. The rust-resistant coating and vented design contribute to long-term durability. While no specific warranty information is provided, the rotor is engineered for consistent performance and reliability under normal operating conditions.
