Check
the tyres for dama geand the cor rect tyre
tread dep thboth before and af ter use on a race‐
trac k.Only then is it safe todrive on a racetrack
and on public roads.
As a result of the driving style and at high ambi‐
ent temp eratures, when driving on a racetrack it
may be necessary tocompensate forthe
inc rease in pressure in warm tyres byreleasing
air. Even forwa rm tyres, the specified tyre pres‐
sure may only be exceeded bymax. 0.5 bar.
Af terth e tyres ha vecooled down again, you
must readjust the tyre pressure in accordance
with the specifications in order todrive on public
ro ads. Suspension

The
factory setting pr ovides a good compromise
fo r driving on public roads and on a racetrac k.
Ve hicle measurements
Even small changes tothe suspension settings
alter the driving characteristics of theve hicle. To
ensure optimal driving characteristics, the speci‐ fi
ed values and tolerances of the individual sus‐
pension settings must be complied with. The
driving characteristics of theve hicle may other‐
wise be undesirable.
Ve hicle measurements are requ ired in thefo llow‐
ing situations:
R theve hicle height has changed in relation to
th e optimised setting.
R theve hicle is frequently subjected tovery
high loads, e.g. when driving over kerbs.
Therefore, check theve hicle height at regular
inter vals and, if necessar y,per form vehicle
measurements.
Note s on suspension components
Despite regular checks, and rega rdless of
whe ther there leva nt suspension components

Mo vethe high-pressure cleaner nozzle
around whilst cleaning. The waterte mp era‐
ture of the high-pressure cleaner must not
exc eed 60 °C.
R obser vethe information on the cor rect dis‐
ta nce in the equipment manufacturer's oper‐
