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

The DFC Brake Rotor - Drilled and Slotted - Black product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with a black zinc-coated hat finish. This design enhances heat dissipation and reduces brake fade while providing corrosion resistance. The directional surface pattern is optimized for vehicles requiring precise braking response, such as the Cadillac Corvette and Chevrolet XLR.

Technical Details and Specifications

This disc brake rotor features a nominal thickness of 26 mm and a discard thickness of 24 mm, ensuring a clear service life indicator. The rotor’s vented design allows air to flow between the rotor faces, reducing heat buildup during braking. The 305 mm outside diameter and 48.4 mm overall height are engineered to match the OEM specifications for the specified Cadillac and Chevrolet models. The zinc black hat finish provides a durable rust-resistant coating, helping maintain rotor integrity over time. The rotor includes five bolt holes with a diameter of 13.5 mm arranged on a 120.6 mm bolt circle diameter, ensuring proper fitment and secure mounting.

Applications and Problem Solving

• Replacement for worn or warped rotors on Cadillac Corvette and Chevrolet XLR
• Improves heat dissipation to reduce brake fade during aggressive driving
• Slotted and drilled surface helps remove brake dust and gases for consistent braking
• Rust resistant coating prevents corrosion in humid or wet environments
• Directional design enhances braking response and pedal feel

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 24 mm before installation. Clean the rotor surface to remove any protective coating or debris prior to mounting. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 13.5 mm diameter holes on a 120.6 mm bolt circle. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction as indicated by the surface pattern.
