These Porsche 991 GT3 and GT3 RS carbon ceramic brake discs are our Gen 3 replacement for the factory PCCB discs, front and rear, on both the 991.1 and 991.2 cars. If your GT3 or GT3 RS has worn or damaged PCCB discs, this is how you replace them.
Gen 3 discs are built with continuous long carbon fiber in a 3D-woven, bonded structure. Factory discs use chopped fiber. That difference is what we build the Gen 3 disc around, and it’s the reason we make these ourselves instead of reselling factory parts.
Carbon ceramic discs can’t be machined or resurfaced like iron rotors, so replacing them is the only fix, and the part number has to be right. Porsche revised these discs several times across the 991 run, and the current numbers supersede the earlier ones. The full history is under “Replaces” below, so you can match it to what’s on your old disc or your parts records.
Fit new pads with new discs. We have PCCB pads for these cars on a separate page. We ask for your VIN on every order so we can confirm your build before the discs ship.
