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.

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
Less weight. More road contact.
