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.

participating in a racing event. The term racing includes but is not exclusive to: wheel
to wheel competition, timed competitive events, autocross or other off-road track
events.
Splitter
• The splitter is not covered for wear on the rub strips or damage due to contact with parking blocks, speed bumps, curbs, s loped tarmac, etc. The warranty is not valid if
adjustments or modifications are made to the splitter.
Wing
• The warranty does not cover any adjustments or modifications made to the wing or if the original fasteners or positions have been changed.
Tires
• 12 months / 12,000 miles - Excessive tire wear due to track events, autocross,competition, etc. are not covered.
Brake Pads/Rotors
• 12 months / 12,000 miles - Excessive brake pad and rotor wear due to track events,autocross, competition, etc. are not covered. No warranty for noise complaints.
Adjustable Coil-over Shocks
• The factory warranty is 12 months / 12,000 miles. KW Suspensions has an extendedsupplier warranty up to 36 months or 36,000 miles. The warranty is not valid if
modifications or improper adjustments are made to the factory settings.

MAINTAINING YOUR VEHICLE

VEHICLE STORAGE
We recommend that you follow these guidelines for storing your vehicle for extended
periods.
• Fill the fuel tank. This will prevent water condensation inside the tank. If you plan to store your vehicle more than two months, add an anti-oxidant fuel stabilizer to the
fuel tank.
• Change the oil to remove any corrosive combustion related acids in the crankcase.
• Check that the radiator coolant level of protection is to at least -20°F (-29°C).
• Make sure that all tires are inflated to the optimum pressure.
• Wash and wax the vehicle to protect the finish.
• Store the vehicle in a dry, well-ventilated location.
• Move the wiper blades away from the windshield.
• Block the wheels. Do not apply the parking brake.
• Cut blocks of plywood about the same size of the tires. Cover each block with indoor/outdoor carpeting and place them between the tires and concrete. This will
prevent tire flat spotting.
• For long-term storage, remove the tires and put the vehicle up on blocks. Stack the tires on plywood and cover wit h a tarp to prevent flat spotting.
• If the vehicle will be subjected to freezin g temperatures, either remove the battery and
store it in a dry, well ventilated area or connect a trickle charger (1.5 Amp) with
automatic shutdown / overcharge protection to the battery. However, do not leave the
trickle charger hooked up to the battery without being plugged in to a 110 Volt AC
outlet, as this will result in further drain on the vehicle's battery. If the vehicle is not
going to be driven in the next three weeks, per form the battery recharge procedure in
the Service Manual. Then, either disconnect the b attery at the negative terminal or use
the “Battery Save Feature” to conserve battery power.
NOTE: Disconnecting the battery causes the en gine control system to lose memory of
some “learned” functions. After reconnecting the b attery, the engine may run rough until
the control module “relearns” these functions. Using the Battery Save Feature will
prevent the engine controller from loosing its memory.
CAUTION!
Use care when disconnecting the remote positive cable. It is connected to the battery
and can short out to any metal on the vehicle. Always tape or wrap the exposed cable
end to prevent electrical shorts.
• Check the battery every four to six weeks to ensure that the voltage is above 12.40 Volts. The voltage will drop more rapidly in hot temperatures. If battery voltage
drops below 12.40 Volts, follow the battery r echarge procedure in the Service Manual.
