The 911 GT2
Drive is transmitted through a pre-
cision six-speed manual gearbox.
Rear-wheel drive provides driving
dynamics that are similar to those
of a racing car. In the 911 GT2,
Porsche also uses a special system
for conventional manual transmis-
sion: the Launch Assistant (see
page 38) – for maximum accelera-
tion from a standing start.
For a sporty but still comfortable
drive, particularly for this type of
sportscar, the standard suspension
features variable damping providedby Porsche Active Suspension
Management (PASM, see page 48).
This active damping system offers
a wide range of benefits including
greater performance and comfort.
Also standard is Porsche Stability
Management (PSM, see page 50).
For the first time, the integrated
control systems for lateral and lon-
gitudinal dynamics, stability control
(SC) and traction control (TC) can
be fully disabled in two stages for a
more natural drive. This means thecar can also be enjoyed to maxi-
mum effect on the racetrack.
The one-piece 19-inch GT2 alloy
wheels of the 911 GT2 are fitted
with road-legal sports tyres as
standard. In size 325/30 ZR 19 on
the rear, these are 20 mm larger
than on the 911 Turbo. The special
tread and compound enable
tremendous lateral acceleration
and higher cornering speeds as
well as precision handling and
turn-in characteristics on either
road or racetrack. A range ofsetup options is available for
racing use, including ride height,
camber, toe angle and front/rear
anti-roll bars.
Developed in motorsport, and
standard on the 911 GT2 is the
Porsche Ceramic Composite
Brake (PCCB, see page 58).
The discs are made from specially
treated carbon fibre and are
approximately 50 % lighter than
comparable metal alternatives.
The results: better brake perfor-mance, greater agility and lower
fuel consumption.
Sports bucket seats (see page 72)
with folding backrest, integral
thorax airbag and manual fore/aft
adjustment, are fitted as standard.
A perfect driving position is essen-
tial in a car with the performance
potential of the 911 GT2. The latest
Porsche Communication Manage-
ment (PCM, see page 76) is also
fitted as standard. This features
a new 6.5-inch touchscreen for
intuitive control.We believe that you don’t have
to exploit the full potential of
the 911 GT2. But you may well
choose to.

being forced into the turbos,
there is less resistance from
the compressors and therefore
less back-pressure in the
exhaust, which means greater
engine performance.
The engine cover, featuring
the GT2 logo, is made from
lightweight glass-fibre reinforced
plastic (GRP). Twin titanium
tailpipes are elegantly incorpor-
ated within the rear apron design.
Warm air is vented from the braking power, with large air
intakes for improved air flow to
the central radiator and front
brakes. The integral air outlet
ahead of the front lid makes a
major contribution to front-enddownforce. The airstream from the
central radiator is channelled up
over the car, forcing the front end
downwards, thereby enhancing
balance and steering response.
The importance of air in the per-
formance of the 911 GT2 is also
apparent from the large intake
openings in the rear side panels
which supply the intercooler units.The most impressive view is also
the one that others will see most
of all: the rear. The fixed rear wing
with integral lip spoiler ensures
optimum stability at speed.
As the car accelerates and you’re
pressed into your seat, air is
forced through the intake openings
on the rear wing uprights and into
the engine turbocharging system.
This ‘ram air’ effect has a key role
to play in the exceptional efficiency
of the engine. Since air is already Power. Torque. Acceleration. All in
plentiful supply. Nothing else can
match that energy – except the
car’s design. A single glance is all
it takes to realise that fact.
The front end is aerodynamically
adapted for the high thermal
load of the engine and increased
Aesthetically. Aerodynamically. Resistance is futile.
Designing the 911 GT2.engine compartment via cooling
slits at the rear.
The combined effect of all these
aerodynamic modifications is a
drag coefficient of just 0.32 as
well as positive front and rear
downforce. Behind the wheel,
that means better grip, better
directional stability and excep-
tional handling characteristics.
Technically and visually, the
result is the same: a breathtaking
driving machine.

Chassis
Rear axle Front axle
The 911 GT2 chassis is designed
for racecar-like performance on
every type of tarmac from motor-
way to track. The car rides about
25 mm lower than the 911 Carrera
and its lightweight build has
reduced overall weight as well as
the unsprung masses. Agile and
responsive, it is stable and secure– particularly during cornering
manoeuvres.
The front suspension with its
special wheel mounts has
McPherson spring struts with
the wheels mounted individually
on trailing arms and wishbones.
Each front wheel is preciselylocated, ensuring excellent
handling and directional stability
in all road and track scenarios.
Brake spoiler elements provide
efficient cooling for each of the
front brake units.The rear axle assembly consists
of subframe-mounted multi-link
suspension featuring LSA con-
struction (Light, Stable, Agile).
This lightened design featuring
an aluminium cross-member
is an important factor in the
exceptional dynamics of the car.
Ride height, camber, toe angle
and anti-roll bar settings can
all be adapted to individual circuit
characteristics, as befits a racing
Porsche.There is virtually no unwanted
movement between the suspen-
sion and body, thanks to special
features such as metal bearings
with ball joints on the front strut
mounts and rigid cross-members
at the rear. This reduced elasticity
and improved wheel location
enable better handling and turn-in.
The 911 GT2 has an electronic
variable damping system as
standard – Porsche Active Suspension Management (PASM,
see page 48).
This variable
damper system offers two basic
setup modes, ‘Normal’ and
‘Sport’.

The 911 GT2 |Chassis
The 911 GT2 runs on one-piece
19-inch GT2 wheels with anti-
theft protection and wheel
centre caps featuring the GT2
logo. The wheels are extremely
light for their size due to their
special lightweight construction.The resulting reduction in unsprung
masses improves driving dynamics
and performance. Thanks to the
generous internal diameter of the
wheel, large brakes can be fitted
on the front axle. The wheels run
flush with the exterior of the carand come with special sport tyres
as standard.
The wheel dimensions are
8.5J x 19 ET 53 with 235/35 ZR 19
tyres (front) and 12J x 19 ET 51
with 325/30 ZR 19 tyres (rear).The 19-inch sports tyres provide
a large road contact patch.
They offer greater traction
under acceleration and braking,
greater precision in both handling
and manoeuvrability, as well as
higher cornering speeds on dry
road surfaces. In short: even
greater driving pleasure. Note:
increased risk of aquaplaning due
to lower tread profile.Tyre Pressure Monitoring (TPM),
included as standard equipment,
provides early warning of tyre
pressure loss. The driver is
informed via the on-board com-
puter display as well as a separate
indicator light. A tyre repair system
consisting of tyre sealant and
compressor with separate tyre
pressure gauge is also standard.19-inch GT2 wheel

The 911 GT2 |Safety
The 911 GT2 excels in every
respect, be it power, driving
dynamics or safety. Every aspect
of its lighting concept, braking
system, rigid body and ergonomic
interior is fine-tuned to its
performance and to the individual
driver. For example, the sportbucket seats (see page 72) with
folding backrest offer racecar-like
lateral support.
Lighting system.
The standard lighting system
on the 911 GT2 uses the latest
Bi-Xenon gas-discharge technology
to achieve a light quality similar
to daylight. The compact main
headlights provide a broad and
uniform swathe of light that
increases active safety in all
road scenarios and in long,
blind corners in particular.
The brightness of the gas-discharge
system featured in the Bi-Xenon
headlights is approximately double
that of conventional halogen units.
A headlight cleaning system is also
included as standard.
The horizontal indicators in
the outer front air intakes use
high-performance light-emitting
diodes (LEDs) to increase
brightness and visibility.
The high-level third brake light
at the base of the rear screen
is equipped with rapid-response
LEDs.Two additional lights on the inside
of each door offer added conveni-
ence and safety. The kerb light
(white) provides useful illumination
when stepping out of the car.
The safety light (red) warns traffic
approaching from the rear when
the door is open.
