Check the tyres for damage and the correct tyre
tread depth both before and after use on a race‐
track. Only then is it safe to drive on a racetrack
and on public roads.
As a result of the driving style and at high ambi‐
ent temperatures, when driving on a racetrack it
may be necessary to compensate for the
increase in pressure in warm tyres by releasing
air. Even for warm tyres, the specified tyre pres‐
sure may only be exceeded by max. 0.5 bar.
After the tyres have cooled down again, you
must readjust the tyre pressure in accordance
with the specifications in order to drive on public
roads.
Suspension
Suspension settings
The factory setting provides a good compromise
for driving on public roads and on a racetrack.
Vehicle measurements
Even small changes to the suspension settings
alter the driving characteristics of the vehicle. To
ensure optimal driving characteristics, the speci‐
fied values and tolerances of the individual sus‐
pension settings must be complied with. The
driving characteristics of the vehicle may other‐
wise be undesirable.
Vehicle measurements are required in the follow‐
ing situations:
R
the vehicle height has changed in relation to
the optimised setting.
R
the vehicle is frequently subjected to very
high loads, e.g. when driving over kerbs.
Therefore, check the vehicle height at regular
intervals and, if necessary, perform vehicle
measurements.
Notes on suspension components
Despite regular checks, and regardless of
whether the relevant suspension components
are in good condition, the following components
must be replaced after a certain amount of use
on the racetrack:
R
Wheel bolts (

R
Wheel hubs including the wheel bearings
Aerodynamic components
Active aerodynamics profile
& WARNING Risk of becoming trapped
when you manually retract the active aer‐
odynamics profile
Parts of the body could become trapped.
#
Ensure that there is no one in the
sweep of the active aerodynamics pro‐
file when you retract the active aerody‐
namics profile.
#
If someone does become trapped when
you retract it, press the display switch
again immediately.
The active aerodynamics profile will
then extend once more.
The active aerodynamics profile influences the
power output at the front axle. The component is
programmed in such a way that it always moves
into the ideal position for the speed and driving
situation. Do not make any manual interven‐
tions.
