A1-276 Girodisc Porsche 992 GT3 PCCB Front Iron Rotor Conversion

These Girodisc 2‑piece front rotors convert 992 GT3 cars with PCCB (carbon ceramic) to iron rotors. Use the same pad shape as the 991 GT3 iron setup (smaller annulus than PCCB) for better pad availability and weight control. The rotors bolt to OEM hubs and work with factory calipers and ABS.

Vehicle Fitment

• Porsche 992 GT3 with PCCB – Front (iron conversion; use 991 GT3 iron pad shape)

Design & Cooling

USA‑poured high‑carbon iron rings with curved vanes provide excellent heat capacity. The 6061‑T6 aluminum hats are anodized and reuseable; floating hardware uses spring preload to control noise and thermal growth.

Features

• Direct bolt‑on conversion; factory calipers retained
• Optimized annulus for performance pad selection
• 2‑piece floating construction to manage heat and mass
• Serviceable with ring‑only replacements
• Sold/priced per pair
