Smooth track set up:
Front: 4 in. (102 mm)
Rear: 5 3/8 in. (136 mm)
Rough track set up:
Front: 4.375 in. (111 mm)
Rear: 5 1/2 in. (140 mm)
• The rake of the car (or front to rear ride height difference) may also be changed with your ACR suspension. Changing the rake may be beneficial at some tracks. Use
caution when changing the rake angle.
CAUTION!
Depending on your set up, driving styl e, and track condition, some tire to wheel liner
contact may occur. To avoid excessive wheel liner wear, adjust your ride height
accordingly.
Notes on Tuning
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”
Front Rebound Position “6”
Rear Compression Position “5”
Rear 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.
NOTE: Although your vehicle is shipped with 0W40, it is recommended 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.

WHEEL AND WHEEL TRIM CARE
• All wheels and wheel trim, especially aluminum and chrome plated wheels, should becleaned regularly with a mild soap and water to prevent corrosion.
• To remove heavy soil and/or excessive brake dust, use MOPAR
®Wheel Cleaner or
equivalent or select a non-ab rasive,non-acidic cleaner.
CAUTION!
Do not use scouring pads, steel wool, a bristle brush, or metal polishes. Do not use
oven cleaner. These products may damage the wheel's protective finish. Avoid
automatic car washes that use acidic solution s or harsh brushes that may damage the
wheel's protective finish. Only MOPAR
®Wheel Cleaner or equivalent is recommended.
