Dodge 2008 Viper Supplement - Manual (Page 15)

The Viper ACR suspension includes a set of adjustable coil-over
racing dampers built by KW Suspensions. These dampers have been
tuned by SRT handling engineers to provide the maximum handling
performance without sacrificing reasonable road manners.
The two-way adjustable dampers include adjustments for compression
(bump) and rebound dampening.
NOTE: Keep your damper settings at the street positions when
operating your vehicle on the street.
WARNING: Only experienced track drivers should make
adjustments to the suspension settings. Improper suspension
adjustment can disrupt the balance of the vehicle and lead to a
loss of control or accident.
CAUTION: Do not make any adjustments or modifications to the
nitrogen pressure of the damper canisters. This will void the warranty.
The ACR suspension was designed and tuned with an
uncompromising focus on handling. The ride response to road
conditions may be harsher than expected from a typical sports car.
