Detailed Product Description
The DFC Brake Rotor - Drilled and Slotted - Silver from Dynamite Friction is designed specifically for the Pontiac Firebird, ensuring precise fitment and optimal braking performance. The rotor features a vented design that allows air to flow between the rotor surfaces, effectively dissipating heat generated during braking. This helps reduce brake fade and extends rotor life. The directional surface pattern combines drilled holes and slots to improve water and debris evacuation, enhancing wet weather braking and pad bite.
The rotor's nominal thickness is 24.89 mm, with a discard thickness of 23 mm, indicating when replacement is necessary to maintain safe braking. The zinc silver hat finish provides additional corrosion resistance, complemented by a rust-resistant coating on the rotor surface. The rotor includes five bolt holes with an 11.6 mm diameter and a bolt circle diameter of 120.7 mm, matching the Pontiac Firebird's specifications.
About the DFC Brake Rotor - Drilled and Slotted - Silver Line

- Enhances wet weather braking by channeling water away from the rotor surface
- Addresses rotor corrosion issues with rust-resistant coating and zinc finish
- Restores braking performance affected by rotor surface damage or scoring
Installation Notes and Tips
Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants before mounting. Verify bolt hole alignment with the 5-lug, 120.7 mm bolt circle diameter pattern on the Pontiac Firebird. Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors for optimal performance.
