Race Circuit Driving
WARNING
Failure to carry out inspection, maintenance and
replacement measures and incorrect implementation
of the fitting instructions can result in component
failure and accidents.
This is especially true when a high total mileage is
reached when driving on race circuits.
e Make sure that the tools are in perfect condition
and that the torque wrench is set correctly.
e Always make inquiries about the current stipula-
tions and conditions before driving on race
circuits: Contact your authorized Porsche dealer.
Even if all the relevant chassis components are
regularly checked, certain components must still be
replaced after specific time periods if the vehicle is
driven on race circuits.

This applies to central bolts and wheel hubs,
including wheel bearings.
For information on the corresponding replacement
intervals:
f Please see chapter "Vehicle Inspection and
Maintenance for Driving on Race Circuits" on
page 9.
Aerodynamic components
Fig. 7: Rear wing adjustment positions
The aerodynamic stability of the vehicle is greatly
affected by the front end lip and rear wing at high
speeds. These components therefore need to be
checked for signs of damage and to ensure they are
correctly mounted before every race circuit session.
Fig. 8: Rear wing adjustment
The vehicle downforce can be increased for driving
on race circuits.
The rear wing angle of attack can be adjusted to
4 positions to increase the rear axle downforce.
e Tighten the fastening screws of the rear wing to
the prescribed tightening torque of 6 ftlb (8 Nm).
