The 911 GT2 |Safety
The 911 GT2 is equipped as
standard with the Porsche
Ceramic Composite Brake (PCCB)
that has already demonstrated
its performance credentials on
the racetrack, for example, in the
vehicles of the Porsche Mobil 1
Supercup.only much harder than metal, it
is also more resistant to heat.
Even at high temperatures, the
thermal resistance of the PCCB
disc ensures exemplary dimen-
sional stability. The ceramic
material is totally resistant to
The large disc diameter (380 mm
front and 350 mm rear) adds sig-
nificantly to brake performance.
The ceramic discs are made from
a specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at 1,700 ºC.
The material thus produced is notcorrosion and offers excellent
acoustic damping properties.
The pads are mounted in six-piston
monobloc aluminium fixed calipers
at the front, with four-piston units
at the rear. The resulting brake
forces are not only extremely
high, they are also exceptionally
consistent. The pedal response
is fast and precise with only
moderate input required.
PCCB enables shorter braking
distances in even the toughest
road and race conditions. Excel-
lent fade resistance ensures
greater balance when slowing
from racetrack speeds.
The key advantage of PCCB is
the total weight saving of approxi-
mately 50 % over comparable
metal discs. The mounting bells
on both front discs are made
from weight-saving aluminium. As
well as enhancing performance
and fuel economy, there is a major
reduction in both the unsprung
and rotating masses. This, of
course, improves comfort and
road-holding on uneven road
surfaces as well as general
handling and agility.
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 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.

The 911 GT2 |Comfort
pairing is complete, the mobile
phone’s aerial is switched off to
conserve battery charge and the
phone operates via the car aerial.
Depending on the mobile phone
model, this gives access not only
to the numbers on the SIM card
but also to the phone’s internal
memory. Also, depending on the
phone, it can be controlled using
the PCM, the multifunction steering
wheel or the voice control system,
without it ever leaving your pocket.
Mobile phone preparation.
As an option, the mobile phone
preparation kit (with or without
cradle) is available for Bluetooth
®
connection of mobile phones
which only support the hands-free
profile (HFP). For connection by
HFP, the PCM acts merely as a
hands-free system. Here, too, the
mobile phone can remain tucked
away. Only the basic phone func-
tions can be operated using the
PCM. The GSM connection is
established via the aerial of the
mobile phone.**
Universal audio interface.
With this optional feature, the
storage compartment in the centre
console will contain three connec-
tions: one for your iPod
®, one
for a USB stick/MP3 player and
one as an AUX interface for any
chosen compatible audio source.
The iPod
®or USB stick can be
operated conveniently and safely
via the PCM, the multifunction
steering wheel or the voice control
system. The USB connection can
also be used to download data
from the performance display of
the Sport Chrono Package Plus
and the electronic logbook.
Sound Package Plus.
Fitted as standard is Sound Pack-
age Plus. A separate amplifier with
a total rated output of 235 Watts,
combined with nine speakers,
ensures a perfect sound for the
interior.
Electronic logbook.
The optional electronic logbook
allows automatic recording of
mileage, distance covered, date
and time, starting point and desti-
nation on each trip. Once you
have downloaded the logbooks
from the PCM via Bluetooth
®or
via the optional USB interface,
the data can be analysed on
your home PC using the software
supplied. The software complies
with all statutory requirements
for automatic logbooks as speci-
fied by the German revenue
authorities.
TV tuner.
A TV tuner, available as a option,
receives analogue and digital
television broadcasts (DVB-T) to
provide entertainment between
journeys. For your safety, the
TV picture cannot be displayed
while the vehicle is in motion.
Voice control system.
Almost all of the functions of the
PCM can be controlled via the
latest optional voice control sys-
tem. The menu item is read aloud
exactly as it is displayed on thescreen and the voice control
system recognises commands or
number sequences, irrespective
of the speaker. It gives audible
feedback and guides you through
the functions. There is no need to
‘train’ the system. Phone book
entries can be retrieved, a radio
station selected or the navigation
destination entered directly by
speaking whole words, rather than
dictating one letter at a time.
Telephone module.
The optional GSM telephone
module offers convenience and
excellent reception. By inserting a
SIM card directly into the PCM’s
integral SIM reader, calls can be
made using either the hands-free
facility or the optional cordless
handset. For even more conve-
nience, the Bluetooth
®capability
of a mobile phone can be used
to make calls via the SIM Access
Profile (SAP)*. Once automatic

The 911 GT2 |Comfort
True, the sound of the 911 GT2
itself is music to your ears. How-
ever, if you still want to listen to
a concert, there’s the optional
BOSE
®Surround Sound System.It has been optimally designed for
the specific interior acoustics of
the 911 GT2. A total of 13 loud-
speakers, including an active
subwoofer and central speaker,
and a 7-channel digital amplifier
with a rated output of 385 Watts,the 5.1 format, the sound has
already been recorded in a
multi-channel format and is
faithfully reproduced exactly
as the original.
Five dedicated audio channels
(front left, front right, centre,
surround left, surround right) and
a power channel for the bass
frequencies deliver a sound that
is as authentic as it is natural.The digital 5.1 surround sound is
balanced, lifelike and crystal clear.
A 360° sound experience that is
as close to a live performance as
you could imagine.
Naturally, you can also play con-
ventional CDs, either in stereo or
in one of the surround modes
generated by the BOSE
®Center-
point
®technology. The new algo-
rithm of Centerpoint
®II extracts
an even more precise and realistic
sound from the stereo signal.
The SurroundStage
®signal pro-
cessing circuitry developed by
BOSE
®assigns each individual
audio channel, whether sourced
from a DVD or generated by
Centerpoint
®, to a selected combi-
nation of loudspeakers and thus
delivers an optimally balanced
surround sound experience to all
seat positions.
To complement these features,
the BOSE
®Surround Sound
System offers a comprehensive
selection of equaliser presets for
customised sound. The dynamic
loudness function emphasises
the bass notes as the volumedecreases to compensate for
the diminishing sensitivity of
human hearing at these frequen-
cies. In addition, the AudioPilot
®
Noise Compensation Technology
uses a microphone to continuously
measure the ambient noise inside
the vehicle and adapts music
playback automatically to give
a constant sound quality in all
driving conditions.
The 911 GT2 and BOSE®:
two complementary sound
experiences of the highest
quality.
