Outstanding acceleration figures are one way to express performance. We focus not only on the positive, but also the opposite values of acceleration. This is how Porsche has traditionally succeeded in setting standards for deceleration and stability.


The new Cayman models are equipped with four-piston aluminum monobloc fixed brake calipers. This design means that, not only are the brakes extremely resistant to deformation, they are lightweight for a particularly fast and sensitive braking response.


A new generation of brake caliper at the front axle, combined with enlarged brake pads and the

newly developed brake booster, has managed to improve braking and component stability even during continuous use. In addition, brake cooling is optimized by the newly developed brake ventilation system featuring a modified air spoiler at the front and rear axles.


The enhanced dynamics of the Cayman and Cayman S also demand appropriate brake discs. All Cayman brake discs are internally vented and cross-drilled for improved braking in wet conditions. With a diameter of 330 mm, the front brake discs of the Cayman S are 15 mm larger than those of the Cayman. The diameter of the rear brake discs is 299 mm on both models. The brake calipers on the Cayman and Cayman S are finished in black and red, respectively.

The electric parking brake, which can be activated and deactivated manually, is released automatically as you pull away with your seat belt fastened. A hill hold function is integrated as standard for the manual gearbox and for Porsche Dopplkupplung (PDK). It assists you in making a comfortable, smooth and roll-free start on an incline. Whenever you come to halt on an incline, this is detected automatically and the braking effect of the electric parking brake is supplemented by application of the wheel brakes. As long as a gear remains engaged, the brake pressure is maintained at all four wheels. To pull away, simply apply throttle. As soon as sufficient starting torque is available, the brake is released and the vehicle moves off.

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 applied 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 (TM) Supercup.


The cross-drilled PCCB ceramic brake discs for the new Cayman models have a diameter of 350 mm front and rear for even more formidable braking performance.

The use of six-piston aluminum 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 even in the toughest road and race conditions. Excellent fade resistance ensures greater balance when slowing from racetrack speeds.


Another key advantage of PCCB is the extremely low weight of the ceramic brake discs, which are approximately 50% lighter than standard discs of a similar design and size. As well as enhancing

performance and fuel economy, this represents a major reduction in unsprung and rotating masses. 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, track day use and other forms of performance driving can significantly reduce the service life of even the most durable pads and discs. As with conventional high-performance braking systems, we recommend that all brake components be professionally inspected and replaced where necessary after each track event.

Enhanced Porsche Stability Management (PSM) is fitted as standard. This system automatically helps to  maintain stability and traction even at the limits of dynamic driving performance. Sensors continuously monitor the direction, speed, yaw velocity and lateral acceleration of the car. Using this information, PSM is able to calculate the actual direction of travel at any given moment. If the car begins to oversteer or understeer, PSM applies selective braking on individual wheels in order to help restore stability.


Under acceleration on wet or low-grip road surfaces, PSM improves traction – as well as agility, control and safety – using the automatic brake differential (ABD) and antislip regulation (ASR). Integrated ABS is designed to minimize braking distances.

If you prefer an ever sportier drive, PSM can be switched off. For your safety, however, PSM remains set to intervene if the vehicle is braked and ABS assistance is required.


Also included with PSM are engine drag torque control (EDC), precharging of the brake system and brake assist. If you suddenly release the accelerator pedal, PSM automatically prepares for your next action: the braking system is precharged so that the brake pads are already in light contact with the brake discs. Maximum braking power is therefore achieved much sooner. Brake assist detects a panic braking situation and generates the brake pressure required for maximum deceleration.

PSM increases driving stability and safety as well as the agility you have come to expect from a Porsche.

To protect the driver and passenger, the new Cayman models are equipped as standard with full-size and knee airbags, which are inflated in two stages depending on the severity and type of accident (e. g. frontal or offset frontal). In less serious accidents, the airbags are only partially inflated, thereby minimizing discomfort to the occupants.


In addition to the central airbag control unit on the transmission tunnel, a pair of impact sensors are located near the headlights. This allows a crash to be detected and evaluated far sooner and with considerably greater accuracy.

Both new Cayman models are equipped as standard with the Porsche Side Impact Protection System (POSIP). It comprises two side airbags on each side. An integral thorax airbag is located in the outer side bolster of each seat, while the door panels each contain an upwards-inflating head airbag. Each thorax airbag has a volume of 10 liters and each head airbag 15 liters, ensuring excellent protection in the event of a side impact. POSIP additionally includes steel side impact protection elements in the doors.

The bodyshell of the new Cayman models is based on an intelligent lightweight principle involving the composite construction of aluminum and steel. The use of dissimilar but precisely combined components makes it possible to utilise specific material properties exactly where they are needed. Not only does this provide a high degree of safety for the driver, it also offers a considerable weight saving compared with the bodyshell of the previous model. This is why the doors, luggage compartment lid and rear hatch are made entirely of lightweight aluminum. Aluminum accounts for around 44% by weight of the entire bodyshell.

The crumple zones in the front and rear fascias feature integral light-alloy bumpers, while impact absorbers offer additional safety. For the protection of occupants, energy-absorbing padding is used selectively in important areas within the passenger cell.

The new Cayman models are equipped as standard with an immobiliser with in-key transponder. In addition, the Cayman S has an alarm system with contact-sensitive exterior protection. A radar-based interior survaillance system is fitted as standard. For the Cayman, a combined alarm and radar-based interior surveillance system is available as an option.
