Porsche Stability Management (PSM).
PSM is an automatic control system for
providing stabilit y at the limits of dyn­
amic driving performance. In addition to
the anti ­lock braking system, it includes
Electronic Stability Control (ESC) and
Traction Control (TC).
Sensors continuously monitor the direc ­
tion, speed, yaw velocit y and lateral
acceleration of the car. Using this infor ­
mation, PSM is able to calculate the
actual direction of travel at any given
moment. If the car begins to oversteer or
understeer, PSM applies selective braking
on individual wheels to restore stabilit y. What ’s special about PSM in the new
911
GT3? The systems intervene at the
limits of dynamic driving performance
with exceptional sensitivit y and precision.
In addition, the systems can be complete ­
ly deactivated in t wo stages for deliber ­
ately sporty handling.

Porsche Torque Vectoring Plus
(PTV Plus).
Porsche Torque Vectoring Plus is fit ted as
standard and has been specially adapted
to the new 911 GT3. It operates in con ­
junction with an electronically regulated
and fully variable rear differential lock.
Numerous driving parameter inputs are the basis for the system’s active control
outputs. The results are perceptible, par
­
ticularly at the limits of dynamic perfor ­
mance: greater traction, increased lateral
dynamics and a significant improvement
in driving stabilit y under the effects of
load changes in corners and when the car
changes lane. On surfaces with less grip,
such as in the wet, the system strategically
brakes the right or left rear wheel. This
means that, whenever the car enters a
corner, brake pressure is applied to the
inside rear wheel. Consequently, a greater
amount of drive force is distributed to the
outside rear wheel. This improves steering
behaviour and increases agility. In combination, both aspects of PT V Plus
offer tangible benefits, giving you
unrivalled pleasure at every t wist and
turn. It ’s just as well there happens

to be so many waiting on the racetrack.

Reserves I 41
Brakes.
At the limit, you need one thing above all:
reserves. Not only for power, but for
safet y, too. This is possible only with a
race­proven technology on which the
driver can depend at all times. Only this
can free up extra room for manoeuvre,
especially in the red zone.
The new 911 GT3 is therefore equipped
with a particularly powerful yet light ­
weight brake system with a specifically

But never beyond.
matched brake booster. The red six ­piston
aluminium brake calipers on the front axle
and the four ­piston equivalents at the
rear are designed as monobloc units. This
makes them tougher and enables a more
rapid response and release of the brake,
even under heav y loads.
That’s not all. The brake dimensions on
the new 911 GT3 have been enlarged to
cope with the increase in engine power.
The brake discs are 380 mm in diameter not only at the front but now also at

the rear. Thanks to their t wo ­piece
construction with cast iron brake discs
and aluminium brake chambers, they
reduce weight and thus the unsprung
and rotating masses. The brake discs
are cross ­drilled and internally vented
for powerful braking even in adverse
weather conditions. Or when pitted
against the challenges of motorsport.
