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 heat dissipation. This directional rotor design helps reduce brake fade and maintain consistent braking performance under demanding conditions. The zinc silver hat finish and rust resistant coating contribute to corrosion protection, making it suitable for daily driving and spirited use on Mercedes-Benz C-Class vehicles.

Technical Specifications and Features

This disc brake rotor features a 300 mm outside diameter and a 5-lug bolt pattern with a 112 mm bolt circle diameter, matching the factory specifications for Mercedes-Benz C180, C200, and C300 models. The rotor’s nominal thickness is 12 mm, with a discard thickness of 10.3 mm, ensuring safe replacement intervals. The directional slotted and drilled surface improves water and debris evacuation while enhancing pad cleaning and heat dissipation. The zinc silver hat finish and rust resistant coating protect against corrosion, extending rotor life and maintaining performance.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves braking response and pad bite on Mercedes-Benz C180, C200, and C300
• Helps prevent rotor warping caused by excessive heat buildup
• Minimizes rust and corrosion for longer rotor lifespan
• Maintains consistent braking performance in wet or dirty conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 10.3 mm before installation. Clean the rotor surface to remove any protective coatings or residues prior to mounting. Verify the 5-lug bolt pattern and 112 mm bolt circle diameter match your vehicle’s hub. Use proper torque specifications for lug nuts to avoid rotor warping. Directional rotors must be installed with the correct rotation direction for optimal performance.
