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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the demands of drivers who require consistent braking performance under various driving conditions, making it suitable for Acura TL models that need reliable replacement rotors.

Technical Specifications and Features

This disc brake rotor is vented to allow better airflow and heat dissipation during braking, which helps prevent brake fade. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor measures 310 mm in outside diameter and 45.4 mm in overall height, fitting precisely on Acura TL vehicles. It features a directional surface with drilled holes and slots to channel away dust, gas, and water, improving braking efficiency. The rotor includes five bolt holes with a diameter of 12.7 mm and a bolt circle diameter of 114.3 mm, matching the Acura TL’s hub specifications. The zinc silver hat finish and rust-resistant coating protect against corrosion, maintaining rotor integrity over time.

Common Applications and Problem Solving

• Replacement for worn or warped brake rotors on Acura TL
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Maintains consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion that can compromise rotor lifespan

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 coating or debris prior to mounting. Use proper torque specifications for the 5 lug bolts with 12.7 mm diameter to secure the rotor. Verify the directional surface orientation matches the vehicle’s rotation direction for optimal performance. It is recommended to replace brake pads when installing new rotors to ensure even wear and braking efficiency.
