Product Description

The Girodisc PCCB Front Iron Rotor Conversion is a track-proven 2-piece rotor upgrade designed for Porsche 991 GT3, GT3 RS, GT2 RS, and 718 GT4 RS models equipped with factory PCCB carbon-ceramic brakes. This system replaces expensive OEM ceramic rotors with high-performance cast iron discs and lightweight aluminum hats, delivering improved braking consistency, better heat management, and significantly reduced long-term operating costs. Engineered as a direct bolt-on solution, it retains factory calipers, ABS calibration, and brake bias while dramatically improving durability for aggressive street and track use.

Fitment Notes

  • Fits Porsche 991.1 / 991.2 GT3, GT3 RS, GT2 RS with factory PCCB

  • Also compatible with 718 Cayman GT4 RS (PCCB-equipped)

  • Direct replacement for OEM front PCCB rotors — no modifications required

  • Requires use of 991 GT3 iron rotor pad shape (smaller annulus vs PCCB pads)

  • Maintains OEM calipers, ABS function, and brake bias

Included

  • Pair of 2-piece front floating rotors (left & right)

  • 6061-T6 aluminum rotor hats (pre-assembled)

  • High-strength alloy steel drive pins and mounting hardware

  • Pre-assembled floating hardware with anti-noise spring washers

Product Specs

  • Rotor type: 2-piece floating iron rotor conversion

  • Material (disc): Proprietary cast iron alloy

  • Material (hat): CNC-machined 6061-T6 aluminum

  • Design: Curved vane internal cooling (centrifugal airflow design)

  • Mounting: Floating system with 12 high-strength drive pins

  • Rotor size: ~410mm front (PCCB equivalent sizing)

  • Serviceability: Replaceable rotor rings (reuse hats)

  • Sold as: Pair (front axle)

Product Features

  • Direct PCCB replacement: Bolts on with no modification while retaining OEM braking systems and geometry.

  • Improved heat management: Cast iron and curved vane design dramatically improve cooling and reduce brake fade under repeated high-load braking.

  • Floating rotor design: Allows axial/radial movement to reduce stress, improve pedal feel, and prevent cracking under heat cycling.

  • Lower operating cost: Iron rings are inexpensive to replace vs costly PCCB rotor replacement.

  • Better pad compatibility: Uses smaller iron pad shape, unlocking significantly more pad compound options for track and street.

  • Balanced performance: Maintains factory brake bias and ABS efficiency without requiring a full big brake kit.
