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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction offers rotors designed with both drilled holes and slots to improve water and gas evacuation during braking. This design helps maintain consistent brake pad contact and reduces brake fade under demanding conditions. The zinc silver hat finish provides corrosion resistance, extending rotor life, while the vented rotor design aids in heat dissipation for improved performance on Mazda 3 and Mazda 3 Sport vehicles.

Technical Specifications and Features

This disc brake rotor is vented to allow airflow between the rotor surfaces, which helps reduce heat buildup during braking. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, indicating when replacement is necessary. The rotor surface is both drilled and slotted, providing a directional braking surface that enhances pad bite and helps remove debris and moisture. The rotor’s hat is coated with a rust-resistant zinc silver finish, while the disc surface has a plain finish. It features five bolt holes with a bolt circle diameter of 114.3 mm and a center hole diameter of 72 mm, matching the Mazda 3 and 3 Sport specifications.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda 3 and Mazda 3 Sport
• Improves braking performance in wet or humid conditions by evacuating water
• Reduces brake fade during extended or aggressive braking
• Addresses rotor corrosion issues with rust-resistant coating
• Maintains consistent brake pad contact through directional slotted and drilled design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (23 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear
• Use proper torque specifications for the 5 lug bolts (bolt circle diameter 114.3 mm)
• Check compatibility with Mazda 3 and Mazda 3 Sport models before installation
• Inspect brake pads for wear and replace if necessary to optimize performance
