This vented disc brake rotor features a directional, slotted, and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Audi S4 vehicles
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Nominal thickness of 22 mm with a discard thickness of 20 mm
• Rust-resistant zinc black hat finish for corrosion protection
• 5 bolt holes with a 112 mm bolt circle diameter
• Overall diameter of 300 mm and height of 36 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that promotes airflow between the rotor surfaces, helping to dissipate heat more effectively during braking. The rotor's surface is both drilled and slotted, which assists in removing brake dust, gases, and water from the contact area, improving brake pad bite and reducing the risk of brake fade. The directional brake surface ensures optimal performance when installed in the correct orientation.

The rotor has a nominal thickness of 22 mm and a discard thickness of 20 mm, indicating when replacement is necessary to maintain safe braking. The hat section is finished with a zinc black coating, providing rust resistance and extending the rotor's service life. With 5 bolt holes and a bolt circle diameter of 112 mm, this rotor is designed to fit securely on the Audi S4 hub assembly.

DFC Brake Rotor - Drilled and Slotted - Black Product Line

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on delivering rotors with enhanced heat management and corrosion resistance. This product line combines drilled holes and slots on the rotor surface to improve braking efficiency and durability, making it suitable for performance-oriented vehicles like the Audi S4. The black zinc finish on the hat area adds an extra layer of protection against rust, which is critical for maintaining rotor integrity over time.

Applications and Problem Solving

• Improves brake cooling to reduce fade during aggressive driving
