Dynamite Friction 830-74034L Disc Brake Rotor - Front Left

Overview of Dynamite Friction DFC Geoperformance Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (part number 830-74034L) is engineered for enhanced braking performance on select Audi and Volkswagen models. Designed with a vented, directional surface, this rotor offers improved heat dissipation and consistent stopping power for vehicles like the Audi A3 Quattro and Volkswagen Golf R.

• Vented disc brake rotor with drilled and slotted surface
• Nominal thickness of 30 mm and discard thickness of 27 mm
• Rust resistant coating for extended durability
• Geospec silver grey hat finish for corrosion protection
• 5 bolt holes with 112 mm bolt circle diameter
• Directional brake surface optimized for heat and debris management
• Outside diameter of 340 mm and overall height of approximately 50 mm

Detailed Product Features and Specifications

This disc brake rotor features a vented design that promotes efficient heat dissipation, reducing the risk of brake fade during demanding driving conditions. The drilled and slotted surface enhances water and gas evacuation, improving braking consistency in wet or high-performance scenarios. The rotor’s nominal thickness is 30 mm, with a discard thickness of 27 mm, ensuring a reliable service life before replacement is necessary.

The rotor hat is finished in Geospec silver grey, providing additional corrosion resistance alongside the rust resistant coating applied to the rotor surface. With 5 bolt holes spaced on a 112 mm bolt circle diameter and a center hole diameter of 65 mm, this rotor is compatible with multiple Audi and Volkswagen models including the A3 Quattro, Arteon, CC, Golf R, GTI, Jetta, Q3, S3, Tiguan, and TTS Quattro.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line focuses on delivering rotors that combine advanced surface treatments with structural design to optimize braking performance. The drilled and slotted pattern is directional, designed to channel heat and debris away from the braking surface, which helps maintain consistent pad contact and reduces the risk of glazing. This line is suitable for drivers seeking rotors that balance everyday usability with enhanced performance characteristics.

Applications and Problem Solving

• Improves braking performance on Audi and Volkswagen models under varied driving conditions
• Reduces brake fade caused by excessive heat buildup
• Minimizes corrosion and rust formation for longer rotor life
• Enhances water and debris evacuation to maintain consistent braking in wet weather
• Provides a direct replacement rotor for vehicles requiring a 5-lug, 112 mm bolt circle diameter rotor

Installation Notes and Tips

Ensure the rotor is installed on compatible Audi or Volkswagen models listed in the fitment. Verify the bolt hole pattern and rotor dimensions before installation. It is recommended to inspect brake pads and hardware during rotor replacement to maintain optimal braking system performance. Proper torque specifications should be followed when securing the rotor to the hub.

Quality Assurance and Warranty

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust resistant coating and Geospec silver grey hat finish contribute to the rotor’s durability and corrosion resistance. Warranty details are provided by the manufacturer and should be reviewed prior to purchase for specific coverage information.
