From the start, Porsche has been synonymous with motorsport. Ever since 1948, when we found our identity on the racetrack, we have taken the experience we have gained and transferred it to the road. The optional Porsche Ceramic Composite Brake (PCCB) is a fine example. This brake system has already had to cope with the harshest requirements of motor racing and is fitted in cars that compete in demanding events, such as the Porsche Mobil 1 Supercup. The cross-drilled PCCB ceramic brake discs for the 911 Carrera have a diameter of 350 mm front and rear for even more formidable braking performance.
The use of six-piston aluminium monobloc fixed brake calipers on the front axle and four-piston units at the rear – all finished in yellow – ensures extremely high brake forces which, crucially, are exceptionally consistent.
PCCB enables shorter braking distances in even the toughest road and race conditions. The key advantage of PCCB is the extremely low weight of the ceramic brake discs, which are approximately 50% lighter than standard discs of similar design and size.
As well as enhancing performance and fuel economy, this represents a major reduction in unsprung and rotating masses.
The consequence is better roadholding and increased comfort, particularly on uneven roads, as well as greater agility and improved handling.
The demands of racetrack use mean that additional maintenance tasks will be required alongside the routine maintenance work scheduled as part of standard maintenance intervals.
The advantages offered by the PDCC in terms of driving dynamics are enhanced still further by the Porsche Torque Vectoring Plus system and the electronically controlled rear-axle differential lock with variable locking effect. The system optimizes steering behavior and traction for a sporty driving experience.
