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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide enhanced braking consistency and resistance to brake fade, making it suitable for daily driving and spirited use on the Honda CR-Z. The silver zinc coating on the rotor hat offers additional protection against corrosion, extending the rotor's service life.

Technical Specifications and Features

This disc brake rotor is a solid type with a nominal thickness of 9 mm and a discard thickness of 8 mm, ensuring a clear maintenance threshold. The rotor's surface is both drilled and slotted, which helps evacuate gases and debris from the brake pad interface, improving braking efficiency. The rotor features a plain disc finish and a zinc silver hat finish that resists rust and corrosion. It has five bolt holes and stud/lug holes, each with a diameter of 12.6 mm, arranged on a 114.3 mm bolt circle diameter. The overall diameter of the rotor is 260 mm, with a height of 31.3 mm and a center hole diameter of 64.2 mm. The directional brake surface is designed to optimize braking performance when installed correctly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Honda CR-Z vehicles
• Improves heat dissipation to reduce brake fade during extended braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Addresses corrosion issues with rust-resistant coating
• Enhances braking response with slotted and drilled surface design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify that the bolt hole pattern matches the Honda CR-Z specifications (5 bolts, 12.6 mm diameter, 114.3 mm bolt circle). Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 8 mm. Properly torque all lug nuts to manufacturer specifications to avoid rotor warping.
