• Nominal thickness: 25 mm with discard thickness at 22 mm
• Overall diameter: 312 mm with a height of approximately 49.9 mm
• Rust resistant zinc silver hat finish and plain disc finish
• 5 bolt holes with a bolt circle diameter of 112 mm
• Directional brake surface optimized for heat and debris management

Detailed Product Features and Specifications

This DFC Brake Rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for maintaining consistent stopping power. The drilled and slotted surface pattern helps evacuate gases, dust, and water, reducing brake fade and improving wet weather performance. The rotor’s zinc silver hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 25 mm and a discard thickness of 22 mm, this rotor meets OEM specifications for durability and safety.

The rotor is designed with 5 bolt holes and a bolt circle diameter of 112 mm, compatible with a range of Audi and Volkswagen vehicles including the A3, Golf Alltrack, Jetta, Passat, Tiguan, and TT models. The directional surface ensures proper installation orientation for optimal performance.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve braking efficiency and rotor cooling. This product line is tailored for drivers who require enhanced brake surface ventilation and debris removal, which is especially beneficial for performance-oriented or daily-driven Audi and Volkswagen vehicles. The silver zinc coating on the rotor hat adds a layer of rust resistance, helping maintain rotor integrity over time.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping and extends rotor lifespan
• Helps maintain consistent pedal feel under heavy braking
• Prevents rust and corrosion on rotor hats for longer durability

Installation Notes and Tips

• Ensure rotor is installed with the directional surface facing the correct rotation direction
• Check bolt hole alignment with vehicle hub (5 bolt holes, 112 mm bolt circle diameter)
• Verify rotor thickness before installation; replace if below discard thickness of 22 mm
• Use proper torque specifications for lug nuts to avoid rotor damage
• Inspect brake pads and hardware during rotor replacement for optimal system performance

Quality Assurance and Warranty

Dynamite Friction manufactures the 631-74053R rotor to meet or exceed OEM standards for fit, form, and function. The rust-resistant coating and vented design contribute to the rotor’s durability and consistent braking performance. Warranty details should be confirmed with the point of purchase or manufacturer documentation.
