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

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 design helps reduce brake fade and maintain consistent braking under demanding conditions. The silver zinc coating on the rotor hat enhances corrosion resistance, making it suitable for vehicles exposed to varying weather conditions.

Technical Description and Fitment

This disc brake rotor is specifically compatible with Infiniti models such as the QX30 and Mercedes-Benz models including the B250e, B Electric Drive, CLA250, GLA200, and GLA250. The rotor’s 5-lug bolt pattern with a 112 mm bolt circle diameter ensures proper fitment on these vehicles. The solid rotor design with drilled and slotted surface improves ventilation and helps maintain optimal braking performance by dissipating heat and gases generated during braking. The zinc silver finish on the hat section provides additional protection against rust and corrosion, extending the rotor’s service life.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response with directional drilled and slotted surface
• Protects against rust and corrosion for longer rotor life
• Restores braking performance on Infiniti QX30 and Mercedes-Benz B250e, CLA250, GLA200, and GLA250 models

Installation Notes and Tips

Ensure the rotor is installed on the correct side, as it features a directional braking surface. Verify the bolt pattern and lug hole diameter match your vehicle specifications. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance. Clean the rotor surface before installation to remove any protective coatings or residues.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and precision machining contribute to consistent braking performance and durability. Please refer to the manufacturer’s warranty information for coverage details.
