Porsche brakes set standards worldwide for stopping power and stability. For the new Boxster models, braking performance is as essential as driving performance.

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

The 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. These two characteristics have also been optimized by the newly developed brake ventilation system with a modified air spoiler at the front and rear axles.

The enhanced dynamics of the Boxster and Boxster S also demand appropriate brake discs. All Boxster brake discs are internally vented and cross-drilled for improved braking in wet conditions. On the Boxster S, the diameter of the front brake discs has been enlarged by .59 in. to 12.99 in. At the rear, the diameter is the same as on the Boxster – 11.77 in. The brake calipers on the Boxster and Boxster S are black and red respectively.

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 Supercup.

The cross-drilled PCCB ceramic brake discs for the new Boxster 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 in even 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 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, trackday 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 every track event.

Enhanced Porsche Stability Management (PSM) is fitted as standard. This system automatically maintains stability even at the limits of dynamic driving performance. Sensors continuously monitor the 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 restore stability.

Under acceleration on wet or low-grip road surfaces, PSM improves traction – as well as agility 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. ABS and ABD remain switched on at all times. 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.

To protect the driver and passenger, the new Boxster models are equipped with full-size 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 is located near the headlights. This allows a crash to be detected and evaluated far sooner and with considerably greater accuracy.

Both new Boxster 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 .35 cu.-ft. and each head airbag .52 cu.-ft., ensuring excellent protection in the event of a side impact even with the hood open. POSIP additionally includes steel side impact protection elements in the doors.

Dual rollover protection creates survival space in the event of a rollover or side impact. The front rollover protection element is made from super and ultra high-strength steels. The supplemental safety roll bars located behind the seats are a composite construction of aluminum and steel. They are fully trimmed to blend in and provide an excellent level of safety. The upper seat belt guides are mounted on the supplemental safety roll bars for easier fastening.

The bodyshell of the new Boxster 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 utilize specific material properties exactly where they are needed. Not only does this provide a high level of safety for the driver, it offers a considerable weight saving compared with the bodyshell of the previous model. This is why the doors of both luggage compartment lids are made from lightweight aluminum.

The crumple zones in the front and rear aprons 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.

Both new Boxster models are equipped as standard with an immobilizers with in-key transponder. In addition, the Boxster S has an alarm system with contact-sensitive exterior protection. A radar-based interior surveillance system, which enhances protection with the hood closed, is available on request. A combined alarm and radar-based interior surveillance system is available as an option for the Boxster.
