Details on the DFC Brake Rotor - Drilled and Slotted - Black Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The zinc black hat finish and rust resistant coating extend the rotor’s service life by protecting against corrosion, making it suitable for Mazda 3 and Mazda 5 vehicles that require reliable stopping power under varied driving conditions.

Technical Specifications and Features

This rotor is vented to improve heat dissipation, which helps maintain consistent braking performance. The slotted and drilled surface is directional, meaning it is designed to rotate in a specific direction to maximize pad bite and reduce debris buildup. The rotor measures 300 mm in outside diameter with a nominal thickness of 25 mm and a discard thickness of 23 mm, ensuring it meets OEM standards for replacement parts. The zinc black hat finish and rust resistant coating protect the rotor from corrosion, extending its durability.

Compatible Vehicles and Applications

• Compatible with Mazda 3 models
• Compatible with Mazda 3 Sport models
• Compatible with Mazda 5 models
• Ideal for addressing brake fade and overheating issues
• Suitable for replacing worn or warped rotors

Installation Notes and Tips

Ensure the rotor is installed with the correct directional orientation to maintain optimal braking performance. Verify bolt hole alignment with the 5-lug, 114.3 mm bolt circle diameter pattern. Clean the rotor surface before installation to remove any protective coatings or residues. Check the rotor thickness to confirm it is above the discard thickness of 23 mm before installation.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and zinc black hat finish contribute to long-term durability.
