Porsche Active Suspension
Management (PASM).
PASM is an electronic damping
control system. Available on
both Cayman models, it offers
continuous adjustment of
individual damping forces based
on current road conditions and
driving style. Agility and driving
pleasure are significantly
enhanced while retaining the
car’s natural ride quality. Equipped
with PASM, the car rides 10 mm
lower than with the standard
steel-sprung suspension.
The driver can choose one of
two setup modes, ‘Normal’ or
‘Sport’. While the first is a blend
of performance and comfort, the
‘Sport’ setup ratings are generally
much firmer, enabling greater
agility on the racetrack. In either
mode, the system responds to
changing loads by automatically
applying the optimum damping
rate on each individual wheel.
The rates are selected from a
range of map options which are
specially adapted to the unique
dynamics of the Cayman and
Cayman S.
The movement of the body is
continuously monitored under
acceleration, braking and cornering
manoeuvres, as well as on poor
road surfaces. Other sensors
provide additional information on
lateral acceleration, steering
angle, brake pressure and engine
torque. A dedicated control unitprovides real-time analysis and
damper adjustment as defined
for the respective setup mode
(‘Normal’ or ‘Sport’). The result:
greater stability and more
consistent occupant comfort.
If, when ‘Sport’ mode is selected,
the quality of road surface drops
below a certain threshold, the
system immediately switches
to
a softer rating and restores
the car’s traction and grip.
When the road surface improves,
PASM returns to the original,
harder ratings. The system
remains active in ‘Normal’ mode,
too, automatically switching to a
harder setup if the car is driven
more assertively. As the dampers
become stiffer, the car becomes
more stable and driver control is
improved.

a more natural and involving
response to lateral and longitudinal
forces. Cornering agility is
considerably enhanced, with
greater scope for oversteer on
turn-in and exit. This additional
manoeuvrability is particularly
apparent in lower-speed sequences
and bends.
For maximum dexterity, PSM can
be set to standby while the car is
still in ‘Sport’ mode. PSM simply
monitors the forces acting on the
car and will only intervene in the
most critical scenarios, e.g., when
ABS assistance is required on both
front brakes.
To help you quantify this increase
in performance, the Sport Chrono
Package includes a compact timer
with swivel display which is
centrally located on the dashboard.
Functions are accessed via the
control stalk for the on-board
computer. Analogue dials measure
hours, minutes and seconds, while
a separate digital field displays
whole seconds, tenths and one
hundredths of a second. The digital
field runs in parallel with a second
digital display which is conveniently
located in the instrument cluster.
Sport Chrono Package Plus.
This enhanced Sport Chrono option
is available in conjunction with the
optional Porsche Communication
Management (PCM – see page 86).
It offers all the same functions as
the Sport Chrono Package as well
as some additional information
options and features.

Lap or journey times can be
viewed, stored and analysed using
a special performance display in
PCM. The information available
includes time elapsed and
distance travelled on the current
lap, as well as the number of laps
completed and their respective
times. You can also view the
current fastest lap as well as the
remaining range till empty. Driving
times can be recorded for any
stretch of road, and benchmark

SafetyPerformance is crucial in a
genuine sportscar. But then so are
all aspects of safety. At Porsche,
we believe that nothing is more
important than this balance of
power and control. The stability
of a car is inextricably linked
with its engine and chassis
performance. Neither can be
considered in isolation. Neither
is complete on its own. In the
Cayman and Cayman S, we’ve
used a comprehensive range of
protective features that are
designed around the driver and
passenger. Inherent within themare the very highest standards of
active and passive safety. Only

Safety in the Cayman and Cayman S.
Active safety.
Active safety is an integral part of
every new Porsche design. Each
new vehicle concept incorporates
systems and components which
are developed with one aim in
mind: total safety for you and your
passengers.The suspension and steering – the
basic platform of the car – have a decisive role to play. On the
Cayman and Cayman S, they offer
generous reserves of safety,
even at racetrack speeds. Equally
important are the reserves
of power, which enable rapid
overtaking manoeuvres. Bringing
Night-time driving is equally
assured thanks to a highly
effective front and rear lighting
concept. The low front foglights
offer excellent illumination,
precisely where you need it most.
A high-level third brake light is
neatly integrated at the base of
the large rear screen. In addition
to the obvious safety benefits,
the front and rear lighting on the
Cayman and Cayman S create
a unique ‘night design’.

This optional headlight system
offers greater light output in
low-beam mode, improved
illumination up to the light/dark

The brakes are cooled using a
special ventilation system which
channels air from the front
of the car to every part of each
assembly. This arrangement
ensures consistently high levels
of performance and durability,
particularly during heavy use.
The internally vented discs on the
new Cayman measure 298 mm
in diameter at the front of the car
and 299 mm at the rear. On the
Cayman S, the front diameter
is 318 mm. On both models, the
discs are cross-drilled to improve
wet-weather response and
minimise unsprung weight. The
calipers on the new Cayman
have a black anodised finish, while
those on the Cayman S are
painted red.

Both the Cayman and Cayman S
are exceptionally quick under
acceleration. Even more impressive
is the speed of response from
the standard braking system.
Several times more powerful
than the flat-six engine, the
brakes are crucial to the overall
performance of each car.
All four brake calipers have a
four-piston monobloc aluminium
construction. Key characteristics
include excellent rigidity, compact
dimensions and a very modest
contribution to unsprung weight.

lighter than metal, but also
harder and more resistant to
high temperatures.
Within each disc is a system of
internal channels which provide
highly efficient heat dispersal,
particularly during heavy use. An
area of ongoing development,
we’ve now doubled the number
of channels and optimised the
airflow characteristics. With twice
the number of internal walls, thenew PCCB disc has even greater
structural stability. The ring of
vent openings around the outer
rim is one of the key distinguishing
features of this technology.
Matched to the disc is a special
brake-pad compoun d offering
rapid deceleration and consistent
friction properties. The front pads
are mounted in six-piston monobloc
aluminium calipers, while those at
the rear come in four-piston units.
Porsche Ceramic Composite
Brake (PCCB).
The Cayman S is also available
with a carbon fibre-reinforced
ceramic brake system: the
Porsche Ceramic Composite
Brake (PCCB). The PCCB disc is
made from a specially treated
carbon-fibre compound that is
silicated in a high-vacuum process
at 1,700 ºC. The result is a
product that is not only much
The overall response is fast and
precise, with only moderate pedal
force required. The front disc
diameter – 350 mm – is larger
than that of the standard metal
disc. The longer radius brings
increased leverage and therefore
additional performance.
Even at high temperatures, the
thermal resistance of the ceramic
disc ensures excellent dimensional
stability. The ceramic material istotally resistant to corrosion and
offers excellent acoustic damping
properties. Braking distances
are significantly reduced in even
the toughest road and track
conditions. Inherent fade resistance
ensures optimum balance when
slowing the car from high speed.

The key advantage of PCCB is
its ultra-lightweight construction.
Compared with conventional metal
discs, it offers a remarkable
weight saving of approximately
50 %.
As well as enhancing performance
and fuel economy, this represents
an enormous reduction in both
unsprung and rotating mass –
important factors when it comes
to handling, agility and comfort.

it can never suspend the laws of
physics, PSM does provide that
extra margin of safety whenever
you need it most. A key component
in PSM is a specially optimised
anti-lock braking system (ABS)
offering safer deceleration and
shorter braking distances. PSM
is also invaluable when applying
the throttle on low-grip surfaces.
Here, it uses the ABD (automatic
brake differential) and ASR
(anti-slip regulation) functions to
maintain traction and stability.
In order to retain the car’s natural
agility, PSM combines a high
trigger threshold with precision
input characteristics.
Porsche Stability
Management (PSM).
This automatic vehicle stability
control system is standard
equipment on both Cayman
models. Throughout each journey,
PSM uses a range of sensors to
monitor the direction, speed, yaw
velocity and lateral acceleration
of the car. Using this information,
it is possible 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
stability and optimum speed. WhileThe PSM threshold is raised
higher still when ‘Sport’ mode is
selected on the optional Sport
Chrono Package/Sport Chrono
Package Plus. The resulting
drive is much more involving,
particularly at speeds up to
around 70 km / h (44 mph). If
you’d rather enjoy the car
unassisted, the system can be set
to standby. When ‘Sport’ mode is
selected, PSM will only intervene
under heavy braking where both
front wheels are in danger of
locking. In ‘Normal’ mode, PSM
automatically becomes active
as soon as one of the front
wheels requires ABS assistance.The upper section of each door
features additional reinforcements
(3) which enhance the rigidity of
the car. This upper load path (4)
is used to channel energy into
the side of the car and thus
provide additional protection for
the passenger cell.
Passive safety.
Both Cayman models easily
comply with all statutory
requirements in respect of frontal,
side, diagonal, rear impact and
rollover protection.
The bodyshell structure contains
a highly resilient passenger
cell offering exceptional crash
protection. At the front of the
car, the cell is protected by a
patented system of longitudinal
and transverse members (1). In
the event of an accident, energy
is absorbed and distributed by
the front-end structure, thereby
minimising cell deformation.
Additional features include a
bulkhead cross-member (2) made
from super high-strength steel.
This element is designed to
absorb impact forces from the
longitudinal members and thus
protect both front footwells.
