Dynamite Friction 830-73057R Disc Brake Rotor - Front Right

Overview of Dynamite Friction DFC Geoperformance Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (part number 830-73057R) is engineered for Audi vehicles including the A4, A4 Quattro, A5, A5 Quattro, and Q5 models. Designed to enhance braking performance, this vented disc brake rotor features a directional, slotted, and drilled surface to improve heat dissipation and maintain consistent stopping power.

• Compatible with Audi A4, A4 Quattro, A5, A5 Quattro, and Q5
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design with 320 mm outside diameter
• Rust resistant coating for extended durability
• Geospec silver grey hat finish for corrosion resistance
• 5 bolt holes with 112 mm bolt circle diameter
• Nominal thickness of 29.8 mm and discard thickness of 28 mm

Detailed Product Features and Specifications

This disc brake rotor is constructed with a vented design to allow better airflow and heat dissipation during braking, reducing the risk of brake fade. The rotor measures 320 mm in outside diameter and has an overall height of 52.2 mm. Its surface is both drilled and slotted in a directional pattern, which helps to evacuate gases, dust, and water from the braking surface, improving pad contact and braking consistency. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance, complemented by a rust resistant coating on the rotor body. The 5 bolt holes and stud/lug hole circle diameter of 112 mm ensure proper fitment on compatible Audi models. The nominal thickness is 29.8 mm, with a discard thickness of 28 mm, indicating when the rotor should be replaced to maintain safe braking performance.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced thermal management and surface design. The drilled and slotted features are engineered to improve braking efficiency by reducing heat buildup and removing debris from the rotor surface. This product line is suitable for drivers seeking reliable performance and durability in demanding driving conditions, particularly for Audi vehicles listed in the fitment.

Applications and Problem Solving

• Improves braking performance on Audi A4, A4 Quattro, A5, A5 Quattro, and Q5 models
• Reduces brake fade caused by excessive heat buildup
• Minimizes rotor surface corrosion with rust resistant coating
• Enhances pad bite and braking consistency in wet or dusty conditions
• Maintains structural integrity with vented rotor design for prolonged use

Installation Notes and Tips

Ensure the rotor is installed on compatible Audi models with a 5-lug bolt pattern and 112 mm bolt circle diameter. Verify the rotor thickness before installation; replace if below the discard thickness of 28 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor warping. It is recommended to inspect brake pads and hardware during installation to ensure optimal braking system performance.

Quality Assurance

Dynamite Friction manufactures the 830-73057R rotor to meet industry standards for durability and performance. The rust resistant coating and Geospec silver grey hat finish contribute to corrosion resistance, extending rotor life. While specific warranty details are not provided, this rotor is designed to maintain consistent braking performance within the specified thickness limits.
