Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction offers rotors designed with enhanced surface features to improve braking efficiency. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the vented rotor construction promotes better heat dissipation. The zinc silver hat finish provides corrosion resistance, extending rotor life under typical driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to improve cooling during braking, which helps maintain consistent performance and reduces the risk of warping. The rotor’s nominal thickness is 16 mm, with a discard thickness of 14 mm, ensuring safe replacement intervals. The rotor measures 309.5 mm in outside diameter and 67 mm in overall height, fitting precisely on Acura RL models. The 5-bolt hole pattern with a 14.7 mm diameter and 120 mm bolt circle diameter matches factory specifications. The rotor surface is directional, featuring both drilled holes and slots to optimize braking under various conditions.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Acura RL
• Improves heat dissipation to reduce brake fade during heavy use
• Helps prevent brake pad glazing by maintaining surface cleanliness
• Reduces rust and corrosion with zinc silver hat finish and coating
• Maintains braking performance with vented rotor design

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 14 mm before installation. Clean the rotor surface to remove any protective coatings or residues before mounting. Verify the 5-lug bolt pattern and 120 mm bolt circle diameter match the vehicle hub. Proper torque specifications should be followed to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fit and function. The rust-resistant coating and zinc silver hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, adherence to discard thickness and proper installation will ensure reliable service life.
