  • Compatible with Pontiac GTO vehicles
  • Directional slotted and drilled surface for improved brake cooling
  • Vented rotor design to reduce heat buildup
  • Rust-resistant zinc silver hat finish
  • 5 bolt holes with 12.7 mm diameter and 120 mm bolt circle diameter
  • Nominal thickness of 18 mm with a discard thickness of 16 mm
  • Overall diameter of 286 mm and height of 79.5 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Silver line, which focuses on delivering enhanced braking efficiency through advanced surface treatments. The rotor’s slotted and drilled design helps evacuate gases, dust, and water from the braking surface, reducing brake fade during aggressive driving or heavy braking conditions. The vented rotor construction improves airflow, allowing for better heat dissipation and maintaining rotor integrity under stress.

The rotor’s zinc silver hat finish provides corrosion resistance, extending the service life of the part. With a 5-lug bolt pattern and a bolt hole diameter of 12.7 mm, this rotor is designed to fit securely on Pontiac GTO models. The nominal thickness of 18 mm ensures durability, while the discard thickness of 16 mm indicates when replacement is necessary to maintain safe braking performance.

Applications and Problem Solving

  • Replaces worn or warped rotors on Pontiac GTO vehicles
  • Addresses brake fade caused by overheating during high-performance driving
  • Improves braking response in wet or dusty conditions with slotted and drilled surface
  • Prevents rust and corrosion on rotor hats for longer service life
  • Maintains consistent braking performance under heavy load or repeated stops

Installation Notes and Tips

Ensure the rotor surface is clean and free of any contaminants before installation. Verify the bolt hole pattern matches the vehicle’s hub assembly (5 lug, 12.7 mm diameter, 120 mm bolt circle). It is recommended to replace brake pads simultaneously to optimize braking performance. Check rotor thickness regularly and replace when thickness reaches the discard limit of 16 mm.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Pontiac GTO. The rust-resistant coating and vented design contribute to long-term durability. Please consult the manufacturer or distributor for specific warranty details related to part number 631-52017L.
