Fits Porsche 911 GT3 Cup (997) models.

Designed for high-performance track use, the GiroDisc D1-066 slotted front replacement rings are engineered to restore the braking efficiency of your 2-piece rotor system. These rings are manufactured from a proprietary high-carbon iron alloy, providing superior thermal capacity and durability compared to standard replacement parts. The directional curved vane design maximizes airflow and heat dissipation, ensuring consistent pedal feel even under heavy racing conditions.

  • Slotted Friction Surface: Maintains a clean pad surface and allows brake gases to escape, preventing glazing and fade.
  • Premium Metallurgy: High-carbon content increases resistance to thermal shock and heat checking.
  • Direct Fitment: Replaces worn rings on existing GiroDisc 2-piece hats for Porsche 997 GT3 Cup applications.
  • Installation Hardware: Includes a full set of high-strength hardware to ensure secure mounting to your rotor hats.
  • Manufacturer Part Number: D1-066
