Detailed Product Description

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on providing enhanced braking through improved heat dissipation and debris removal. The rotor’s vented design allows air to flow between the rotor surfaces, reducing heat buildup during braking. The drilled and slotted surface helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and reducing the risk of brake fade.

Constructed with a plain disc finish and a zinc silver coated hat, this rotor offers corrosion resistance to extend service life. The rotor’s dimensions, including a 300 mm outside diameter and 48.6 mm height, are engineered to meet the exact specifications required for Mazda 3, Mazda 3 Sport, and Mazda 5 vehicles. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter ensures proper fitment and secure installation.

Applications and Problem Solving

• Replaces worn or warped rotors on compatible Mazda 3, 3 Sport, and 5 models
• Addresses brake fade caused by excessive heat during heavy braking
• Improves braking performance in wet or dusty conditions with slotted and drilled design
• Reduces rust and corrosion on rotor surfaces for longer durability
• Restores proper rotor thickness to maintain safe braking distances

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the 5-lug bolt pattern and 114.3 mm bolt circle diameter match your vehicle’s hub. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal braking performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for Mazda 3, Mazda 3 Sport, and Mazda 5 vehicles. The rust resistant zinc silver hat finish and vented rotor design contribute to durability and consistent braking performance. While no specific warranty information is provided, Dynamite Friction products are generally backed by quality control standards to ensure reliability and fitment accuracy.
