On request, we can equip your Boxster S with a brake system that has already had to cope with the harshest requirements of motorsport: the Porsche Ceramic Composite Brake (PCCB).
The ceramic brake discs have a diameter of 350 mm front and rear – for extremely powerful braking. The brake discs are formed from a specially treated carbon-fibre compound that is silicated in a high-vacuum process at approximately 1,700˚C. Not only are the resulting discs much harder than standard discs, they are more resistant to heat. The low thermal expansion of the brake discs prevents deformation under heavy braking. Furthermore, the ceramic brake discs are totally resistant to corrosion and offer more favourable noise-damping properties.
Six-piston aluminium monobloc fixed calipers on the front axle and four-piston units at the rear provide a high and constant brake pressure. The pedal response is fast and precise with only moderate input required.
All the necessary ingredients are there for a short braking distance, even in the toughest conditions. Moreover, safety under braking at high speeds is increased thanks to the excellent fade resistance of PCCB.
The key advantage of PCCB is that the brake discs are approximately 50% lighter than standard discs of similar design and size. A factor that helps to reduce unsprung and rotating masses on the vehicle. The consequence of this is better road holding and increased comfort, particularly on uneven roads, as well as greater agility and improved handling.
Please note that circuit racing, trackday use and other forms of performance driving can significantly reduce the service life of even the most durable brake pads and discs. We recommend that all brake components be professionally inspected and replaced where necessary after every track event.
