Detailed Product Features and Specifications

This DFC Brake Rotor features a drilled and slotted surface designed to reduce brake fade by improving heat dissipation and gas venting during braking. The vented rotor design further enhances cooling efficiency, which is critical for maintaining consistent brake performance under demanding conditions. The directional surface pattern optimizes water and debris removal, making it suitable for both street and light performance applications.

Constructed with a zinc silver hat finish and a rust-resistant coating, this rotor offers enhanced corrosion protection, extending the service life of the component. The rotor’s dimensions, including a 279 mm outside diameter and 101.5 mm overall height, are engineered to meet OEM specifications for a precise fit on compatible vehicles.

Compatible Vehicles and Applications

This rotor is compatible with a range of Buick, Chevrolet, Oldsmobile, and Pontiac models, including:

• Chevrolet Camaro, El Camino, Malibu, Monte Carlo, Nova
• Pontiac Firebird, Grand Prix, GTO, LeMans, Tempest
• Oldsmobile Cutlass, Cutlass Supreme, Omega
• Buick Skylark

It is designed to replace worn or damaged rotors on these vehicles, restoring braking efficiency and safety.

Common Issues Addressed by This Brake Rotor

• Brake fade caused by overheating during heavy braking
• Uneven brake pad wear due to rotor surface irregularities
• Corrosion and rust buildup reducing rotor lifespan
• Vibration or pulsation during braking from warped rotors
• Reduced braking performance in wet conditions

Installation Notes and Tips

Ensure the rotor surface and hub are clean and free of debris before installation. Verify the bolt hole pattern matches the vehicle’s hub (5 holes, 7/16-20 diameter, 120.6 mm bolt circle). Use proper torque specifications for lug nuts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
