Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Brake Rotor - Drilled and Slotted - Black product line, which focuses on rotors with enhanced surface designs to improve braking efficiency and rotor longevity. The drilled and slotted surface helps to evacuate gases, dust, and water, reducing brake fade and improving pad bite. The vented rotor design promotes better heat dissipation, which is critical for maintaining braking performance during extended use.

The rotor's directional surface pattern is engineered to optimize airflow and cooling. The zinc black coating on the hat provides rust resistance, helping to maintain the rotor's structural integrity and appearance over time. With a nominal thickness of 28 mm and a discard thickness of 26 mm, this rotor meets precise wear limits to ensure safe operation. The 5-bolt hole configuration with a 120 mm bolt circle diameter matches the Acura RL specifications for a secure fit.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Acura RL models
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent rust and corrosion on rotor hats for longer service life
• Enhances braking performance in wet or dusty conditions with drilled and slotted design
• Maintains consistent braking feel with directional surface pattern

Installation Notes and Tips

Ensure the rotor is installed with the directional surface pattern oriented correctly according to the vehicle's rotation direction. Verify that the rotor thickness is within the specified limits before installation, discarding if below 26 mm. Use proper torque specifications for the 5 lug bolts with 14.7 mm diameter to secure the rotor. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance.
