Porsche 911 GT3 RS User Handbook Manual page 55

The key advantage of PCCB is the
extremely low weight of the brake
discs which are about 50 % lighter
than standard discs of similar
design and size. In addition, the
monobloc calipers for the 911 GT3
models on the front and rear axle
are made from aluminium, saving
around 4.8 kg per vehicle com-
pared to standard calipers. These
factors not only have an impact
on performance and fuel consump-
tion, but also reduce unsprung and
rotating masses.
The result: better road-holding
and increased comfort, especially
on uneven roads, as well as
greater agility and even better
handling.
Please note that circuit racing
or other forms of performance
driving can significantly reduce
the service life of even the most
durable brake pads and discs.
As with conventional high-
performance braking systems,
we recommend that all brake
· 65 · · 65 ·
components be professionally
inspected and replaced where
necessary after every track event.
