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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features to improve braking efficiency. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the directional surface ensures proper alignment for optimal performance. The zinc silver coating on the rotor hat provides corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring it meets safety standards for replacement. The rotor's outside diameter measures 231 mm, with an overall height of 44 mm. It includes four bolt holes with a diameter of 12.6 mm arranged on a 100 mm bolt circle diameter, matching the Honda Civic's specifications. The center hole diameter is 61 mm, and the rotor surface is finished with a plain disc and zinc silver hat finish for rust resistance.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Honda Civic models
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance under various driving conditions
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances braking response with directional drilled and slotted surface

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle's rotation. Verify bolt hole alignment with the Honda Civic's hub assembly using the 4-bolt pattern and 100 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 10 mm. Proper torque specifications should be followed to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM specifications for Honda Civic vehicles. The rust-resistant zinc silver coating on the rotor hat helps extend durability. While no specific warranty information is provided, the rotor's design and materials support reliable braking performance when installed and maintained properly.
