Dodge 2008 Viper Supplement - Manual (Page 21)

Damper Adjustment
Adjusting from the street settings should be done only at track events.
A recommended starting position for the tracks is:
Front: Compression = Position “6”
Rebound = Position “6”
Rear: Compression = Position “5”
Rebound = Position “5”
• Always start from a known position (full stiff).
• Adjust in small increments (1-2 clicks)
• Record your adjustment settings at all four wheels
• Continually monitor and record your tire pressures
Remember that suspension damping, ride heights, rake angle and
aerodynamic balance all work as a system. As you make changes to
one end of the vehicle, it will affect the balance of the car.
Maintenance and Inspection
Regularly inspect the splitter rub strips and out board knock-in nut.
Regularly inspect all attachments of the aerodynamic components
(see Aerodynamics section).
Track use will greatly increase wear rates and service intervals on your
Viper ACR. Repeated track use requires more frequent fluid changes.
Because of the extreme conditions encountered during track use, any
damage or wear associated with track use is not covered by warranty
(see Warranty section).
NOTE: Although your vehicle is shipped with 0W40, it is recommend-
ed to use Mobil-1 15W50 synthetic motor oil at the track.
Always run a cool down lap at the end of a track outing. For track
outings lasting longer than 25 minutes, an external rear axle cooler
is recommended.
