carbon air outlet in front of the
front lid guides the air flowing
through the central radiator up
over the vehicle, thus increasing
the downforce on the front axle.
Immediately noticeable are the
front wings which are 26 mm
wider, enabling a wider toe angle
and the use of wider tyres. The
19-inch GT2 RS wheels have a
white gold metallic finish.
A further striking feature is the
black ‘GT2 RS’ logo on the side.
The rear with a carbon middle
section makes an impression.
And the carbon lip on the fixed
rear wing sits 10 mm higher.
For extreme driving stability.
For greater efficiency and more
engine power, as the speed in-
creases, additional air is pressed
into the intake channel through
the air inlet channels in the wing
supports. This ram air system
builds up the air in front of the
Lightweight construction.
Anyone who wants to go beyond
the horizon has to work on their
performance – and concentrate
on strength. The way to achieve
this is to make sacrifices. But only
with regard to weight. The new
911 GT2 RS is 70 kg lighter than
the 911 GT2. Its weight-to-power
ratio: just 2.21 kg/ hp. For excel-
lent performance. And with rela-
tively moderate fuel consumption.
This is achieved thanks to a whole
series of modifications. In parti-
cular, the use of materials that
are more typically found in motor-
sport. The front lid, the side air
intakes on the charge air cooler,
the slats in front of the front lid,
the rear middle section, the rear
spoiler lip and the rear wing are
all constructed from carbon. As
are the lightweight bucket seats
and door sills with the ‘RS’ logo.
The front mud flaps are also
available in carbon as an option. Instead of the usual steel, the
diagonal struts on the rear axle
are made from aluminium. As are
the fixed calipers of the PCCB on
the front and rear axle. The engine
cover, rear window and rear side
windows are made from a synthetic
material. In addition to this, the
new 911 GT2 RS has light weight
door panels with side pads and
door pulls. Throughout the body,
much of the soundproofing has
been removed and the interior
soundproofing has also been
reduced.
The lightweight single mass
fly wheel makes the engine even
more responsive. Weight has
even been reduced in the body
structure: there are no fittings for
a roof transport system and there
are no reinforcements for fasten-
ing the seat belts in the floor.
The battery in the new 911 GT2 RS
is also lighter. A lithium ion battery
which provides an additional weight
saving of over 10 kg compared to the conventional standard battery
is available as an option. The
lithium ion battery is inserted in
the vehicle and can easily be
replaced by the standard battery
for use on the racetrack.
In addition, you can opt to do
without the CDR-30 audio system,
the air conditioning and the
Clubsport package. To achieve an
even lower power-to-weight ratio.
Design.
Even the appearance of the new
911 GT2 RS leaves no room for
doubt: it is more powerful than
before.
Power is demanding. So, with
regard to aerodynamics, the design
has been aimed at achieving the
best possible cooling and the
greatest possible downforce. The
large air inlets ensure that the air
is directed straight to the central
radiator and the front brakes. The turbochargers. This relieves the
turbochargers, thus lowering
exhaust gas back pressure and
increasing engine power.
To sum up: a drag coefficient
value of only
0.34. Along with
increased downforce on the front
and rear axles. For better road
holding, greater stabilit y and
excellent handling. In short, a
design that fulfils its purpose:
to create awe.

Porsche Ceramic Composite
Brake (PCCB).
Being in awe also means knowing
when
to brake – when necessary.
The new 911 GT2 RS is equipped
as
standard with the Porsche
Ceramic
Composite Brake (PCCB).
This braking technology has already
demonstrated its performance
credentials on the racetrack,
for example, in the vehicles of
the Porsche Mobil 1 Supercup.
Its
ceramic brake discs have a
diameter of 380 mm at the front
and 350 mm at the back – for
excellent braking power. The ceramic discs are made from
a specially treated carbon-fibre
compound that is silicated in a
high-vacuum process at approxi-
mately 1,700 °C. The resulting
brake discs are much harder and
therefore more resistant to exces-
sive temperatures than cast iron
discs. Typical of PCCB, the low
thermal expansion prevents defor-
mation under heavy braking. Fur-
thermore, the ceramic brake discs
are totally resistant to corrosion
and offer bet ter noise-damping
properties.The use of six-piston aluminium
monobloc fixed calipers on the front
axle and four-piston aluminium
monobloc fixed calipers on the
rear axle ensures a very high and,
above all, constant braking pres-
sure. The brake response is much
faster and more precise and
requires only moderate input.
All the necessary ingredients are
there for short braking distances,
especially in tough conditions.
And safety is also increased when
braking from high speeds, thanks
to the excellent fade resistance
of PCCB.
The key advantage of the ceramic
brake system is in the extremely
low weight of the brake discs: they
are approximately 50% lighter than
cast iron discs of similar design and size. In the new 911 GT2 RS
the calipers on the front and rear
axles are made from light weight
aluminium giving an additional
weight saving of approx. 4.8 kg
compared with stainless steel
calipers. This doesn’t just have
a positive effect on driving per-
formance and fuel consumption.
Above all, it means that the
unsprung and rotating masses
are reduced.
The result is improved road-
holding and comfort, especially on
uneven roads. As well as greater
agilit y and even bet ter handling.
Please note that circuit racing,
trackday use and other forms
of performance driving can sig-
nificantly reduce the service life
of even the most durable pads
and discs. As with conventional
high-performance braking sys-
tems, we recommend that all
brake components be profession-
ally inspected and replaced where
necessary after every track event.
Safety means being able to rely on the
systems working in the background.
