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 precision slots to optimize brake pad contact and heat dissipation. The silver zinc coating on the rotor hat provides corrosion resistance, extending rotor life. This product line is designed to meet the specific braking demands of performance-oriented vehicles like the Audi S4, offering a balance between durability and effective thermal management.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to reduce heat and prevent brake fade during extended use. The rotor’s directional slotted and drilled surface improves water and debris evacuation, enhancing braking consistency in various driving conditions. With a nominal thickness of 30mm and a discard thickness of 28mm, the rotor maintains structural integrity while providing a clear wear limit. The zinc silver hat finish offers rust resistance, helping to maintain appearance and function over time. The rotor features five bolt holes with a 112mm bolt circle diameter, matching the Audi S4’s factory specifications for straightforward installation.

Applications and Problem Solving

• Replaces worn or warped rotors on Audi S4 models
• Improves brake cooling to reduce fade during spirited driving
• Enhances braking performance in wet or debris-prone environments
• Prevents rust and corrosion on rotor hats for longer service life
• Maintains consistent braking feel with directional slotted and drilled design

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is within the nominal range and above the discard thickness limit. Use proper torque specifications for the 5 lug bolts with a 112mm bolt circle diameter to secure the rotor. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance.

Quality Assurance

Dynamite Friction manufactures this rotor to meet OEM fitment and performance standards for the Audi S4. The rust-resistant coating and vented design contribute to durability and consistent braking. While no specific warranty information is provided, the product is engineered to comply with industry quality requirements for disc brake rotors.
