Detailed Product Description

This DFC Brake Rotor - Drilled and Slotted - Silver is specifically designed to meet the braking demands of the Audi S4. The rotor’s vented construction allows air to flow between the rotor surfaces, reducing heat buildup during braking and helping to prevent brake fade. The directional slotted and drilled surface improves water and gas evacuation, which enhances braking consistency in wet or high-performance driving conditions.

The rotor features a rust-resistant zinc silver coating on the hat area to protect against corrosion, while the disc surface maintains a plain finish to ensure optimal pad contact. With a nominal thickness of 22 mm and a discard thickness of 20 mm, this rotor provides a balance between durability and performance. The 5-bolt hole pattern with a 112 mm bolt circle diameter ensures proper fitment on compatible Audi S4 models.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on rotors that combine drilled holes and slots with a corrosion-resistant finish. This product line is designed to improve braking performance by enhancing heat dissipation and reducing brake dust buildup. The silver zinc coating on the hat area adds durability against rust, making these rotors suitable for drivers who require consistent braking performance and longevity.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation on the rotor surface
• Prevents rust and corrosion on the rotor hat for extended service life
• Maintains consistent braking performance for Audi S4 vehicles

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 20 mm before installation. Clean the rotor surface to remove any protective coatings or contaminants prior to mounting. Verify the 5-bolt hole pattern and 112 mm bolt circle diameter match your Audi S4 hub assembly. Properly torque lug nuts to manufacturer specifications to avoid rotor warping.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for fit and function. The rust-resistant zinc silver coating on the hat area helps extend rotor life in corrosive environments. While no specific warranty information is provided, the rotor is designed for durability and consistent performance in Audi S4 applications.
