Detailed Product Description

This Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver is designed to meet the braking demands of mid-size and full-size vehicles such as the Pontiac Grand Prix and Saturn Relay. The rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The drilled and slotted surface aids in debris removal and water dispersion, enhancing brake pad contact and reducing fade under heavy use.

The rotor’s zinc silver hat finish and rust resistant coating provide protection against corrosion, extending the rotor’s service life. With a nominal thickness of 32.2 mm and a discard thickness of 30.7 mm, this rotor ensures safe replacement intervals. The 5-lug bolt pattern with a 115 mm bolt circle diameter fits securely on compatible vehicles, including the Buick Allure and Chevrolet Uplander.

Compatible Vehicles and Applications

• Buick Allure, LaCrosse
• Chevrolet Montana, Uplander
• Pontiac Grand Prix, Relay
• Saturn Terraza

This rotor is ideal for addressing common braking issues such as:

• Brake fade during extended or heavy braking
• Uneven rotor wear causing vibration or noise
• Corrosion and rust buildup reducing rotor lifespan
• Reduced braking efficiency in wet conditions
• Overheating due to insufficient heat dissipation

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern and diameter match your vehicle’s specifications. It is recommended to replace brake pads simultaneously to maintain optimal braking performance. Proper torque specifications should be followed when securing the rotor to avoid warping.
