DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and heat dissipation. This design helps reduce brake fade under demanding conditions, making it suitable for drivers seeking consistent braking performance. The directional surface pattern and rust resistant coating contribute to rotor longevity and reliable operation on compatible vehicles like the Audi A4 and A4 Quattro.

Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type with a nominal thickness of 12 mm and a discard thickness of 10 mm, ensuring safe replacement intervals. The rotor measures 287 mm in outside diameter and 36 mm in height, fitting precisely on Audi A4 and A4 Quattro models. The rotor’s surface is both drilled and slotted, which aids in venting gases and debris from the brake pad interface, improving braking consistency and reducing heat buildup. The directional design of the braking surface optimizes water and dust evacuation during operation.

The rotor hat features a Geospec silver grey finish, enhancing corrosion resistance along with the rust resistant coating applied to the entire rotor. The 5-bolt hole configuration with a 112.2 mm bolt circle diameter matches the factory specifications for secure mounting. The center hole diameter is 68 mm, and the stud/lug hole diameter is 15 mm, ensuring proper fitment and alignment.

Applications and Problem Solving

  • Replacement rotor for worn or warped discs on Audi A4 and A4 Quattro
  • Improves heat dissipation to reduce brake fade during heavy braking
  • Slotted and drilled design helps maintain pad bite in wet or dusty conditions
  • Rust resistant coating prevents premature corrosion and extends rotor life
  • Directional surface aids in debris removal for consistent braking performance

Installation Notes and Tips

  • Ensure rotor thickness is above discard thickness (10 mm) before installation
  • Clean rotor surface to remove any protective coating residue before mounting
  • Verify bolt hole alignment and torque bolts to manufacturer specifications
  • Check compatibility with existing brake pads and calipers on Audi A4 or A4 Quattro
  • Perform a bed-in procedure after installation to optimize rotor and pad contact

Quality Assurance
