2010 PORSCHE BOXSTER S brakes

· 60 ·· 61 ·
Active safety.
Uncompromising sports per-
formance. Comprehensive safet y.
At Porsche, these qualities have

always been inextricably linked.
Just as in the Boxster models
where the body, chassis and
brakes constitute a single inte -
grated system with generous
safety reserves.
The chassis setup allows for an
extremely sport y driving st yle
with exceptional cornering control.
The variable ratio steering is
direct and precise with excellent
feedback from the road.

The braking system ensures
maximum deceleration and

stabilit y. A high power-to -weight
ratio and responsive throt tle
enable easier overtaking and
evasive manoeuvres. Porsche
Stabilit y Management (PSM,

p. 63) fit ted as standard helps
to stabilise the vehicle in critical
driving scenarios, even in
unfavourable weather conditions.
Also contributing to active
safet y is the ef fective headlight
concept which guarantees
excellent vision at night (p. 64).

Braking system.
The Boxster and Boxster S have
a braking system with four-
piston aluminium monobloc brake
calipers fit ted front and rear.
Offering excellent rigidit y, they
are compact and save on weight.
Their superior responsiveness,
for fast and sensitive braking, sets
them apart.
A brake booster reduces pedal
ef fort whilst maintaining powerful
braking. A special ventilation
system, whereby the entire wheel
brake is cooled through openings
in the front end and special
channelling systems, increases
the stabilit y of the brakes during
heav y use.

Both the Boxster and Boxster S
have internally vented brake
discs at the front with a diameter
of 318 mm, whilst the rear discs
measure 299 mm. The result is
impressive braking performance.
The brake discs on the Boxster S
are 4 mm thicker than those
on the Boxster, which increases
stabilit y even further. To distinguish them visually,

the brake calipers on the Boxster
have a black anodised finish
while those on the Boxster S are
painted red.
For reduced weight, bet ter cool -
ing and optimum braking in the
wet, the brake discs are cross-
drilled.

A purist concept doesn’t allow for reserves.
Except when it comes to safety.
