The new 911 GT3 | Chassis
Porsche Active Suspension
Management (PASM), an electronic
damper adjustment system, is
fitted as standard on the new
911 GT3. PASM actively and
continuously controls the individual
damping forces for each wheel
according to current road
conditions and driving style. The
911 GT3 is also 30 mm lower
than the standard 911 Carrera.
At the press of a button, the driver
can choose between two setup
modes. ‘Normal’ mode is designed
for sporty driving on general roads
and on the racetrack in wet
conditions. ‘Sport’ mode is
especially for maximum lateral
acceleration and the best
possible traction on the racetrack.
Depending on which mode is set,
and the road conditions detected,
the system automatically selects
the best damper application
within the two setup ranges.
A range of sensors monitor the
movement of the body during
acceleration and braking or on
uneven surfaces. The PASM
control unit then evaluates this
data and adjusts the damping
force, depending which mode
is selected. Pitch and roll are
reduced and the road contact
of each individual wheel is
optimised.
In ‘Sport’ mode the suspension is
automatically set to a harder rating
specially designed for use on the
racetrack. The system will detect
any unevenness on the surface and
then, to improve road contact, it
switches within a few milliseconds
to a softer rating within the sport
or stiff set-up range. When the
track surface becomes even again,
PASM returns to the original harder
rating.
In ‘Normal’ mode, if the driving
style becomes more dynamic, the
system automatically switches
to a sports-oriented rating within
the normal set-up range. The
suspension becomes stiffer so
that driving stability and safety
are increased.
Normal mode?
A very subjective question.
