Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted by Dynamite Friction is designed to meet the braking demands of Audi A4, A4 Quattro, A6, A6 Quattro, Allroad Quattro, and S4 vehicles. Its vented rotor construction allows for efficient heat dissipation during braking, reducing the risk of brake fade under heavy use. The directional slotted and drilled surface improves water, dust, and gas evacuation from the rotor surface, maintaining consistent brake pad contact and performance. The rotor’s plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance and durability. With a nominal thickness of 30 mm and discard thickness of 28 mm, this rotor ensures a reliable service life while maintaining safety standards.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface designs that improve braking efficiency and rotor longevity. This product line incorporates vented rotors with directional drilled and slotted surfaces, specifically engineered to optimize heat dissipation and debris removal. The Geospec silver grey hat finish and rust resistant coating further contribute to durability, making these rotors suitable for performance-oriented Audi models.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner braking components
• Enhances heat dissipation to prevent rotor warping
• Provides consistent braking performance for Audi A4, A4 Quattro, A6, A6 Quattro, Allroad Quattro, and S4 vehicles

Installation Notes and Tips

Ensure the rotor is compatible with your specific Audi model and verify the bolt pattern matches your vehicle’s hub (5 bolt holes, 112 mm bolt circle diameter). Clean the rotor surface before installation to remove any protective coatings or residues. Use proper torque specifications for lug nuts to avoid rotor damage. It is recommended to replace brake pads when installing new rotors to maintain optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and durable finishes help extend rotor life under normal operating conditions.
