Optional for the new 911 GT3 is brake technology that has already had to withstand the harshest requirements of motorsport: the Porsche Ceramic Composite Brake (PCCB).

To enhance braking performance, the ceramic composite brake discs in PCCB have a diameter of 380 mm at the front and 350 mm at the back. They are made from a specially treated carbon-fibre compound that is silicated in a high-vacuum process at around 1,700 °C. The resulting brake discs are much harder and more resistant to heat than standard discs.

PCCB is characterised by its low thermal expansion which prevents deformation under heavy braking. Furthermore, the ceramic brake discs are totally resistant to corrosion and offer better noise-damping properties.

The use of six-piston aluminium monobloc brake calipers at the front and four-piston units at the rear ensures extremely high brake forces which, crucially, are exceptionally consistent. The pedal response is fast and precise with only moderate input required.

All the prerequisites are there for a short braking distance, even in the toughest conditions. Moreover, safety when braking from high speeds is increased thanks to PCCB’s excellent fade resistance.

The key advantage of PCCB is the extremely low weight of the brake discs which are about 50% lighter than standard discs of similar design and size. In addition, the monobloc calipers for the new 911 GT3 on the front and rear axle are made from aluminium, saving around 4.8 kg per vehicle compared to standard calipers. These factors not only have an impact on performance and fuel consumption, but also reduce unsprung and rotating masses.

The result: better road-holding and increased comfort, especially on uneven roads, as well as greater agility and even better handling.

Please note that circuit racing or other forms of performance driving can significantly reduce the service life of even the most durable brake pads and discs. As with conventional high-performance braking systems, we recommend that all brake components be professionally inspected and replaced where necessary after every track event.
