Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors with enhanced surface features such as drilled holes and slots to improve brake pad bite and heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of vehicles like the Mazda 5 that require durable and efficient braking components.

Technical Specifications and Features

This disc brake rotor is constructed as a solid rotor with a plain disc finish and a zinc silver coated hat to resist rust. The rotor measures 302 mm in outside diameter and 41.1 mm in overall height, with a center hole diameter of 71.8 mm. It includes five bolt holes arranged on a 114.3 mm bolt circle diameter, matching the Mazda 5's hub specifications. The directional slotted and drilled surface improves water and debris evacuation while enhancing pad contact for consistent braking performance.

Applications and Problem Solving

• Replacement rotor for worn or warped brake rotors on Mazda 5
• Improves heat dissipation to reduce brake fade during extended use
• Helps prevent rust and corrosion with zinc silver coating
• Enhances braking response with directional drilled and slotted design
• Maintains proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 9 mm before installation. Clean the rotor surface to remove any protective coatings or debris. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter on the Mazda 5 hub. 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

Dynamite Friction manufactures this rotor to meet OEM specifications for fit and function on Mazda 5 vehicles. The rust resistant zinc silver hat finish helps extend service life. While no specific warranty information is provided, the rotor is designed to maintain nominal thickness of 10.8 mm and discard thickness of 9 mm to ensure safe braking operation.
