Porsche Ceramic Composite
Brake (PCCB).
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 defor -
mation under heav y braking.
Furthermore, the ceramic brake
discs are totally resistant to
corrosion and offer more favour -
able 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, safet y
under braking at high speeds is
increased thanks to the excel-
lent 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 bet ter
road holding and increased
comfort, particularly on uneven
roads, as well as greater agilit y
and improved handling.
Please note that circuit racing,
trackday use and other forms of
performance driving can signifi -
cantly 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.
Porsche Stability Management
(PSM).
PSM, which comes as standard,
is an automatic control system
that stabilises the vehicle at the
limits of dynamic driving per-
formance. Sensors continuously
monitor driving direction, speed,
yaw velocit y and lateral accel -
eration. Using this information,
PSM computes the actual direc -
tion of motion. If this direction
deviates from the desired course,
PSM initiates braking inter-
ventions targeted at individual
wheels in order to stabilise the
vehicle.
Under acceleration on wet or
low-grip road surfaces, PSM
improves traction using the ABD
(automatic brake differential)
and ASR (anti-slip regulation)
functions, giving an agile
response. When ‘Sport ’ mode is
selected on the optional Sport
Chrono Packages (p. 56), the
PSM intervention threshold is
raised to enable greater driver
involvement – particularly at
speeds of up to approximately
70 km/ h (45 mph). The integral
ABS can further reduce the
braking distance.

Instruments.
Each black circular dial in the
instrument cluster – aluminium-
coloured in the Boxster S –
provides important information
at a glance. In the centre is the
analogue rev counter with digital
speedometer and a customis - able display of key data from the
standard on -board computer.
Additional data, such as average
fuel consumption, fuel range or
the data of the optional TPM can
be shown as desired.
The right-hand dial displays the
outside temperature and shif t
pat tern of the optional Porsche
Doppelkupplung (PDK), as well
as the selected gear. The dial on
the lef t contains the analogue
speedometer with digital trip
meter and total distance display.
The design and legibilit y of the
dials are also enhanced by the
white backlight illumination.
Steering wheels.
The Boxster models are equipped
as standard with a three -spoke
sports steering wheel with full- size
airbag. As an option, you can
specify a three-spoke multifunction
steering wheel with integrated
but tons for the most essential
audio and, where applicable, navi -
gation and telephone functions. The multifunction steering wheel
is available in a choice of smooth
leather, Aluminium Look, carbon
or macassar finish.
In combination with the optional
Porsche Doppelkupplung (PDK),
the three-spoke steering wheel can
be optionally fit ted with gearshift
switches – and is also available as
a multifunction steering wheel if
Boxster | Comfort
required. Also available on request
is the three-spoke sports steering
wheel with gearshif t paddles
(p. 46). For extra comfort in the
cold winter months, there is the
optional steering wheel heating
(available only in conjunction with
seat heating). It is available for
all steering wheels, except the
three-spoke sports steering wheel
with gearshift paddles.
