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 feature both drilled holes and slots on the braking surface. This design helps to reduce heat buildup and evacuate gases and debris during braking, which can improve rotor longevity and maintain consistent stopping power. The zinc silver coating on the rotor hat provides additional corrosion resistance, making it suitable for various driving conditions.

Product Specifications and Features

This solid rotor measures 304.5 mm in outside diameter and 60.8 mm in height, fitting vehicles with a 5-lug bolt pattern and a 114.3 mm bolt circle diameter. The rotor’s nominal thickness is 9 mm, with a discard thickness of 7.5 mm, ensuring clear service limits for safety. The directional slotted and drilled surface enhances brake pad bite and helps maintain cooler operating temperatures, which is critical for Acura CR-V and Honda RDX drivers seeking consistent braking performance.

Applications and Problem Solving

• Compatible with Acura CR-V and Honda RDX models requiring 5-lug, 304.5 mm diameter rotors
• Addresses brake fade caused by excessive heat during prolonged braking
• Helps reduce rotor surface corrosion with rust-resistant coating
• Improves water and debris evacuation for better wet weather braking
• Maintains braking efficiency by preventing gas buildup between pad and rotor

Installation Notes and Tips

Ensure the rotor is installed on vehicles matching the specified bolt pattern and dimensions. The directional surface requires correct orientation to function properly; verify the rotation direction before installation. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 9 mm. Use proper torque specifications on lug nuts to avoid rotor warping.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet OEM specifications for Acura and Honda vehicles. The rust-resistant zinc silver finish helps extend rotor life under normal driving conditions. While specific warranty details are not provided, Dynamite Friction products typically adhere to industry standards for durability and performance.
