Preamble to 911 GT3 Race Circuit
Session
Race Circuit Driving
DANGER
Driving at excessive speeds and risky maneuvers may
lead to loss of control over the vehicle.
e Adapt your driving style and maneuvers to your
personal ability, the road and weather conditions,
as well as the traffic situation.
e Motor sports equipment such as six-point seat
belts, Clubsport package fire extinguisher or
emergency cut-off switches must not be used on
public roads.
f Please see chapter "Safety and Driving Pleasure"
in the Owner's Manual.
Until only a few years ago, the race circuit perfor-
mance potential that comes with your 911 GT3 was
exclusive to pure, specially prepared race vehicles.
Compared with driving on roads, driving on race
circuits involves disproportionately high vehicle
loads, which pure race vehicles are able to withstand
thanks to short maintenance and component recon-
ditioning intervals. This includes carrying out checks
and replacing individual components where neces-
sary after each race circuit session, up to overhauling
entire assemblies after a specified period.
What is meant by "driving on race circuits" is opera-
tion of the vehicle close to or at its performance limits
during use on race circuits (e.g. in the context of track
days, driver training events, slalom competitions etc.)
or other courses closed to the public (e.g. hill climb
races).
The 911 GT3 is a high-performance sports car
approved for road use, but one that can handle
a broad spectrum of driving, from everyday road use
through to sessions on a race circuit. However, this
broad spectrum requires significantly different
servicing in some cases, depending on how the
vehicle is used.
Standard servicing intervals may, for example,
be absolutely adequate for a "normal" load profile on
public roads, whereas for vehicles driven on the race
circuit, additional checks must be performed before
and after each session.
The maintenance requirements and service intervals
which Porsche specifies for normal road use are not
sufficient for vehicles used in a race circuit.
For information on service intervals for race circuit
driving:
f Please see chapter "Vehicle Inspection and
Maintenance for Driving on Race Circuits" on
page 9.
This chapter explains the most important technical
issues to look out for if you drive your vehicle on the
race circuit. It also lists the checks that you must
carry out before each session.
The main objective here is to help you ensure that
your 911 GT3 remains in good technical condition at
all times, including during driving on the race circuit.
Race Circuit Driving
Specifics of Individual Vehicle
Assemblies
Given the particular vehicle loads associated with
race circuit driving, there are certain additional issues
that require attention. These are summarized below
for the most important assemblies:
Brake system
Loads on the entire brake system during race circuit
driving are significantly higher than with "normal"
use, partly due to the achievable braking effect and
the higher component temperatures associated
with this.
Brake pads
During driving on the race circuit, the pads (inner and
outer) may exhibit brake pad wear characteristics
which cannot be fully detected by the standard brake
pad wear indicator. Therefore, it is absolutely essen-
tial to visually inspect the pad condition before and
after driving on the race circuit.
The standard brake pads provide the best possible
compromise between day-to-day usability and
sportiness.
Porsche offers special brake pads for particularly
performance-oriented driving on race circuits.
For information on installation options and use on
public roads:
e Contact your authorized Porsche dealer.
NOTICE
Use of non-approved brake pads is not permitted.
