• Nominal thickness of 9 mm with a discard thickness of 7 mm
• Rust resistant zinc black coating on the rotor hat
• Plain disc finish with 5 bolt holes and 5 stud/lug holes
• Outside diameter of 265 mm and center hole diameter of 68 mm
• Bolt circle diameter of 114.3 mm and rotor height of 39 mm

Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Black is designed specifically for select Mazda models, including the Mazda 3, 3 Sport, CX-3, and CX-30. The rotor features a directional surface with both drilled holes and slots, which helps to reduce brake fade by improving heat and gas dissipation during braking. The nominal thickness of 9 mm ensures durability, while the discard thickness of 7 mm indicates when the rotor should be replaced to maintain safe braking performance.

The rotor hat is finished with a zinc black coating that provides corrosion resistance, extending the rotor's service life in various driving conditions. The rotor's 5-bolt hole pattern and 114.3 mm bolt circle diameter match the factory specifications for the compatible Mazda models, ensuring proper fitment and installation.

About the DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a directional surface design. This product line is intended to enhance braking efficiency by promoting better heat dissipation and debris removal from the rotor surface. The black zinc coating on the rotor hat adds rust resistance, making these rotors suitable for drivers seeking reliable performance and longevity in their braking components.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves water and debris evacuation from the rotor surface
• Helps maintain consistent braking performance under high heat
• Prevents premature rotor corrosion with rust-resistant coating
• Ensures proper fitment for Mazda 3, 3 Sport, CX-3, and CX-30 models

Installation Notes and Tips

When installing the 633-80079R rotor, verify the rotor thickness before and after installation to ensure it meets the nominal thickness of 9 mm and does not fall below the discard thickness of 7 mm. Properly torque the 5 lug bolts to the manufacturer’s specifications to avoid rotor warping. The directional surface requires installation in the correct orientation to maximize performance benefits.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fitment and performance. The rust-resistant zinc black hat finish helps extend rotor life by reducing corrosion. While no specific warranty information is provided, adherence to discard thickness guidelines and proper installation will help maintain safe and reliable braking performance.
