911 Carrera 4
Standard suspension.
The front axle is equipped with
McPherson strut suspension and
the wheels are located using a
high-precision arrangement of
longitudinal and transverse links
and reinforced wheel bearings.
The benefits on the road are pre-
cision wheel guidance, excellent
straight-line stability and superior
handling characteristics.
The rear axle has a race-derived
multi-link suspension, following the
LSA concept (Lightweight, Stable,
Agile) for exceptional driving
dynamics. The axle kinematics
significantly reduce the compres-
sion of the vehicle’s suspension
under acceleration. Lightweight
spring struts with aluminium
dampers on the rear axle help
to maximise handling agility.
To steer a true course, you sometimes have
to be able to take the rough with the smooth.

This lightweight construction
keeps the vehicle gross weight
and the weight of the unsprung
masses low. The chassis allows
for safe manoeuvring, even at
high speeds. The pitching of the
body when pulling away and
braking is minimal, as is body
roll in corners. Rolling noises
and vibrations are also kept to a
minimum.
Steering.
The power steering is sensitive
and precise, providing excellent
contact with the road and minimal
steering effort by sportscar stan-
dards. It offers steering precision
comparable with a racecar – even
on those relaxing drives.
A special feature is the variable
steering ratio. Around the straight
ahead position, such as during
motorway driving, the ratio is less
direct. The risk of losing control
of the wheel at high speed is
reduced, with no loss of agility
or feedback.
When the steering wheel is
turned harder, the ratio becomes
more direct, allowing for easier
cornering and parking. The
car has a turning circle of just
10.9 m.
