Track Set Up - Dodge 2016 Viper SRT ACR Owner's Manual

5.5 Track Set Up

Ride Height Adjustment
The factory ride height of your ACR is approximately:
Front: 5.0 inches (126 mm)
Rear: 6.0 inches (154 mm)
Measured from the bottom of frame rail to ground at the axle
centerline with no passengers, a full tank of fuel and tire pressures
set to 35 psi in the front and 29 psi in the rear.
CAUTION:
Depending on your set up, driving style, and track
condition, some tire to wheel liner contact may occur. To avoid
excessive wheel liner wear, adjust your ride height accordingly.
A low ride height setting may not be optimal at all tracks. The
optimum set up for your vehicle also varies with track, driver and
ambient conditions. Here is a recommended starting point for typical
track configurations.
Height Adjustment
Adjusting from the street settings should be done only at track events.
A recommended starting position for the tracks is:
Front: Compression = Position "7" Rebound = Position "5"
Rear: Compression = Position "5" Rebound = Position "3"
• Adjust in small increments (1-2 clicks).
• Record your adjustment settings at all four wheels.
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.
Track Set Up
Front: 4.0 inches (102 mm)
Rear: 5.5 inches (140 mm)
Adjusting lower than the track set up is not recommended.
The rake of the car (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.
