Upgrade the braking feel and serviceability of your Porsche 992 GT3 / GT3 RS with this high-performance iron rotor conversion designed to replace the original PCCB carbon-ceramic fronts. Engineered by GiroDisc, this rotor kit features a lightweight aluminum hat, proprietary vented cast iron rotor disc, and a floating mount system to maintain precision and durability under pressure. With this conversion you combine the weight savings and cooling of a high-end racing rotor while regaining the broader pad selection and service ease of iron discs. Ideal for street, track days, or endurance use, this upgrade brings serious braking performance without losing the premium build quality.
Designed specifically for the Porsche 992 GT3 / GT3 RS with factory PCCB (carbon-ceramic) front setup.
Rotor set is sold in pairs (front only) and replaces the original PCCB front rotors.
Installation by a qualified technician recommended; inspection of hub run-out, torque specs, and pad fitment is required.
Pair of front rotors (left & right) with cast iron rotor discs and aluminum rotor hats.
High strength alloy steel drive pins with anti-noise spring washers for the floating mount system.
Vehicle-specific hardware required to mount the rotor hats to hubs (per kit).
Full installation instructions and specification sheet from GiroDisc.
Material: U.S.-sourced 6061-T6 aluminum rotor hat + proprietary cast iron rotor disc.
Floating mount: 12 high-strength alloy steel drive pins with hardened washers per rotor.
Cooling design: curved vane rotor architecture developed from racing‐application experience to improve air flow and heat dissipation.
Finish: Cadmium-plated pins for corrosion resistance, OEM style hardware, precision machined from start to finish in-house.
Converts the expensive and limited‐pad‐selection PCCB system to a more serviceable iron rotor platform while retaining top-level performance.
Floating rotor hat design allows thermal expansion while maintaining rotor alignment and minimizing noise—ensuring consistent pedal feel under heavy use.
Lightweight aluminum hat combined with a vented iron disc delivers a strong thermal and rotational mass balance for street and track use.
Designed and machined in the USA—everything manufactured and finished precisely to ensure fit, performance and reliability.
Compatible with high performance pad options thanks to the optimized rotor annulus design, giving you extra flexibility for upgrade paths.
Built with racing-derived venting and cooling architecture—helps manage heat build‐up on repeated heavy braking to preserve fade resistance and caliper life.
