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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is engineered to provide improved heat dissipation and reduced brake fade through its vented design and directional drilled and slotted surface. This rotor line is suitable for drivers seeking reliable braking performance with corrosion resistance, thanks to its zinc silver coating on the hat area.

Technical Details and Compatibility

This disc brake rotor features a vented design that helps maintain optimal operating temperatures during braking. The drilled and slotted surface improves water and debris evacuation, enhancing braking consistency. With a nominal thickness of 20 mm and a discard thickness of 18.5 mm, it meets precise wear specifications. The rotor’s bolt pattern includes five 14.1 mm diameter holes on a 108 mm bolt circle, compatible with Ford LS, Jaguar S-Type, Lincoln Vanden Plas, and other specified models. The directional brake surface ensures proper installation orientation for effective performance.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Improves braking response in wet or debris-prone conditions
• Reduces brake fade during extended or aggressive driving
• Addresses corrosion issues with rust-resistant coating
• Restores proper rotor thickness for safe braking operation

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct direction as indicated. Verify bolt hole alignment with the vehicle’s hub using the 5-lug, 108 mm bolt circle pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 18.5 mm. Clean the rotor surface to remove any protective coatings before mounting to ensure optimal pad contact.

Quality Assurance and Warranty
