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

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade and maintain consistent stopping power under demanding conditions. The zinc silver hat finish and rust resistant coating extend rotor life by protecting against corrosion, making it suitable for vehicles exposed to varied weather conditions.

Technical Specifications and Features

This rotor features a vented design that allows air to flow between the rotor surfaces, enhancing cooling during braking. The drilled and slotted surface type is directional, meaning it is optimized for rotation in a specific direction to maximize performance. The rotor measures 259 mm in outside diameter and 48 mm in height, with a nominal thickness of 20.35 mm and a discard thickness of 18.7 mm, ensuring precise fitment and safety compliance. The 5-bolt hole pattern with a 100 mm bolt circle diameter matches the wheel hub specifications of compatible vehicles.

Compatible Vehicles and Applications

• Buick Achieva and Skylark
• Chevrolet Cavalier, Corsica, and Sunfire
• Oldsmobile Cutlass Calais
• Pontiac Grand Am and Sunbird

This rotor is designed to replace worn or damaged rotors on these models, restoring braking efficiency and safety.

Common Issues Addressed by This Rotor

• Brake fade caused by overheating during extended braking
• Uneven brake pad wear due to rotor surface imperfections
• Corrosion and rust buildup reducing rotor lifespan
• Vibration or pulsation during braking from warped rotors
• Reduced stopping power from worn or undersized rotors

Installation Notes and Tips

Ensure the rotor is installed in the correct directional orientation to match the drilled and slotted pattern. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 100 mm bolt circle diameter pattern. Clean the rotor surface before installation to remove any protective coatings or residues. Check rotor thickness against discard thickness (18.7 mm) to confirm suitability for reuse or replacement.

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-52007L rotor to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. Warranty details should be confirmed with the manufacturer or distributor, as they may vary by region and application.
