DODGE VIPER 2010 ZB II / 2.G Service Manual

Adjusting the ride height:
• Raise and support the vehicle. Both left andright side wheels should be lifted off the
ground to allow adjustment of the spring
seats without damage. Never make ride
height adjustments with the suspension
loaded. The helper spring should never be
fully compressed while adjusting ride
heights.
• Remove the wheel and tire assembly.
• Loosen the set screw on the lower spring seat (approx 1 turn).
• To lower the ride height, use the spanner wrench and rotate the lower spring seat counter-clockwise (as viewed fr om below the damper). Use the set screw as a
reference to return to street height.
• To raise the ride height, first turn the seat in the counter-clockwise direction and ensure the threads are clear of debris. Use the spanner wrench and reverse the
direction.
• Tighten the set screw to 22 in-lbs (2.5 N·m). DO NOT over tighten this screw.
• The ride height adjustment sensitivity is as follows: • Front: One turn = 0.104 in. (2.6 mm) height change at frame
• Rear: One turn = 0.134 in. (3.4 mm) height change at frame

PERFORMANCE/ACR

Compression Adjustment
• The compression adjustment (also calledbump) varies the damping of the upward
travel of the wheel relative to the vehicle.
• The compression adjuster is located on the remote canister fixed to the damper body
and has 14 damping positions. Depending
on vehicle ride height, the car may need to
be raised to gain access to the compression
adjuster. To adjust the compression
damping, turn the finge r knob: clockwise
stiffens; counterclockwise softens when
viewed from the top surface of the finger
knob.
• All settings are referenced from the full stiff (position “0”). The “0” position on
compression is achieved by turning the
finger knob clockwise until you cannot turn
it any further.
CAUTION!
To avoid damage to your dampers DO NOT force the finger knob when it stops turning.
Also, NEVER use any tools to adjust the finger knob.
• From the “0” position, turning the adjuster cou nterclockwise will soften the damping.
Count off the clicks and record your setting. Every “click” is a new damping position
(i.e. two clicks softer from the full stiff position is position “2”).

Rebound Adjustment
• The rebound adjustment (also called droop)varies the damping of the downward travel
of the wheel relative to the vehicle.
• The rebound adjuster is located on top of the piston rod and has 19 damping
positions. Depending on vehicle ride height,
the car may need to be raised to gain access
to the rebound adjuster. To adjust the
rebound damping, turn the upper finger
knob: clockwise stiffens; counterclockwise
softens when viewed from above.
•
All settings are referenced from the full stiff
(position “0”). The “0” position on rebound
is achieved by turning the finger knob
clockwise until you cannot turn it any further.
CAUTION!
To avoid damage to your dampers DO NOT force the finger knob when it stops turning.
Also, NEVER use any tools to adjust the finger knob.
• From the “0” position, turning the adjuster cou nterclockwise will soften the damping.
Every “click” is a new damping position (i.e. two clicks softer from the full stiff
position is position “2”).
Street Set Up
• Best Comfort is achieved at the following damper settings and should always be used when driving on the street:
Front Compression Position “13”
Front Rebound Position “18”
Rear Compression Position “13”
Rear Rebound Position “17”
Ride Height Adjustment
• The factory ride height of your ACR is approximately: Front: 514in. (132 mm)
Rear: 6 in. (153 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 29 psi.
• A low ride height setting may not be optimal at all tracks. It will generally be more acceptable to run a lower ride height at a track with smoother surfaces, fewer abrupt
elevation changes and fewer bumps. The optimum set up for your vehicle also varies
with track, driver and ambient conditions. Below is a recommended starting point for
two typical track configurations.

PERFORMANCE/ACR

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.

HARD CORE PACKAGE
• This option is for the Hard Core track enthusiast who is looking for maximum weight
savings.
• The Hard Core Package eliminates the Audio System (including the radio, amplifier,
door speakers and subwoofer). Also delet ed are the under hood silencer pad, the
trunk carpet and the tire inflator. The door speakers are replaced by carbon fiber
panels. The radio is replaced by a lightweight cover that can be configured to mount
the included Lap Timer.
CAUTION!
The tire inflator has been removed from the Hard Core package. There are no
measures for flat tire repair included with this vehicle. It is recommended that drivers
always bring a mobile phone in case of a flat tire.
• The removal of the trunk carpeting reduces sound insulation. It is normal to hear more road and drivetrain noise.
• The Lap Timer kit includes the Timer, Beacon Receiver, a power cord, download kit and the Beacon Transmitter.
• The Lap Timer displays lap times on a large illuminated digital display. It continuously updates the fastest laps and acquires a running data log of all times during the track
event. This data can be do wnloaded for analysis via a USB connection. Refer to your
AiM lap timer manual for instructions.
• The cables to the beacon receiver and power jack include extra long lengths. This is to provide the ability to custom fit the timer and beacon receiver depending on the track
and/or driver preference.
• Note on Lap Timer: For lap timer software updates and technical support contact www.aimsports.com/software/index.html.

INSTRUMENT CLUSTER WARNING LIGHTS
- Tire Pressure Monitoring System (TPMS) Light
• Each tire, including the spare (if provided), should be checked monthly, when coldand inflated to the inflation pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a
different size than the size indicated on the v ehicle placard or tire inflation pressure
label, you should determine the proper tire inflation pressure for those tires.)
• As an added safety feature, your vehicle has been equipped with a Tire Pressure Monitoring System (TPMS) that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflat ed. Accordingly, when the low tire
pressure telltale illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
• Please note that the TPMS is not a subs titute for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire pressure telltale.
• Your vehicle has also been equipped with a TPMS malfunction indicator to indicate
when the system is not operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle start-ups as long as
the malfunction exists.
• When the malfunction indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and wheels allow the TPMS to continue
to function properly.

WHAT TO DO IN EMERGENCIES

CAUTION!
The TPMS has been optimized for the original equipment tires and wheels. TPMS
pressures and warning have been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor damage may result when using
replacement equipment that is not of the same size, type, and/or style. Aftermarket
wheels can cause sensor damage. Do not use tire sealant from a can, or balance
beads if your vehicle is equipped with a TPMS, as damage to the sensors may result.
- Engine Temperature Warning Light
• This light warns of an overheated engine condition.
• If the light turns on and a warning chime sounds while driving, safely pull over andstop the vehicle. If the A/C system is on, t urn it off. Also, shiftthe transmission into
NEUTRAL and idle the vehicle. If the temperat ure reading does not return to normal,
turn the engine off immediately.
• We recommend that you do not operate the vehicle or engine damage will occur. Have the vehicle serviced immediately.
WARNING!
A hot engine cooling system is dangero us. You or others could be badly burned by
steam or boiling coolant. You may want to call an authorized service center for service
if your vehicle overheats.
- Brake Warning Light
• The Brake Warning light illuminates when there is either a system malfunction or the parking brake is applied. If the light is on and the parking brake is not applied, it
indicates a possible brake hydraulic malfunction, brake booster problem or an
Anti-Lock Brake System problem.
• We recommend you drive to the nearest service center and have the vehicle serviced immediately.
WARNING!
Driving a vehicle with the red brake light on is dangerous. Part of the brake system
may have failed. It will take longer to stop the vehicle. You could have an accident.
Have the vehicle checked immediately.
