1.0 Overview
Throughout this manual there are notes of WARNING and CAUTION. Review
each of them before driving this car.
The Dodge Viper SRT ACR is the literal fusion of Street and Racing
Technology. It takes the awe inspiring performance capabilities of the
Dodge Viper SRT to the next level.
The Dodge Viper SRT ACR is not certied as a race car and it is not equipped
with a racing safety cage, racing restraints or other racing safety equipment.
Drive safely.
This booklet is a supplement to your Dodge Viper SRT Owner’s Manual.
Please review the Owner’s Manual in addition to this booklet.
WARNING: The limit handling characteristics of this vehicle are much
different than many other sports cars. Operation of the vehicle in excess
of driver skill and experience can result in crash, injury and/or death.
It is highly recommended that all drivers complete a high performance
driving school prior to operating this vehicle.

2.0 Aerodynamics
2.1 Front Splitter
The Dodge Viper SRT ACR aerodynamics are capable of high levels of
downforce which will noticeably affect the grip and handling of the
vehicle at speeds as low as 50 mph.
Regularly inspect all of the aerodynamic components and attachments
for damage or wear.
Splitters are potent aerodynamic elements usually only found
on purpose built racing cars. The Viper ACR front splitter has
been specially adapted for street use with the addition of several
new features.
• The leading edge has been scalloped back to reduce front
overhang for day to day driving.
• Toughened polymer rub strips have been added to reduce wear
and abrasion on the splitter panel.
• Tension cables support the front edge to allow some upward
deection in minor impacts with ramped surfaces.
In spite of these enhancements, the splitter remains highly vulnerable
to impact because of its position on the car.
The front splitter will not ex or compress against impacts from the
front. If an impact does occur, have the splitter inspected. A cracked
or delaminated splitter should be replaced.

CAUTION: Use care when approaching parking blocks, tall speed
bumps and garage curbs. These surfaces can severely damage
your splitter.
CAUTION: Hard contact with steep ramps may cause damage to
your splitter.
Always leave ample room and be sure to educate anyone you allow to
operate the vehicle.
Use care when driving up to sloped surfaces or over speed bumps.
Approaching a speed bump or a slope at a slight angle may improve
your clearance.

2.2 Splitter Components
The front of the ACR splitter is supported by
stainless steel cables. These cables and their
attachments should be regularly inspected.
The splitter cables have an adjustment capability,
however it is recommended to leave the splitter at
the factory delivered settings. The splitter cables
may have some slack while the vehicle is at rest.
When the splitter is loaded, and the cables are
under tension, the main splitter panel and track
extension should be approximately parallel to the
bottom of frame.
Solid polymer rub strips are attached to the
leading edge of the splitter panel. Regularly
inspect these rub strips to avoid damage to the
carbon ber splitter panel.
NOTE: Splitter extension is supplied in the splitter
extension carrying bag.
Standard Viper ACR
Extreme Viper ACR

CAUTION: Replace rub strips when they are worn down to 3/8 inches (10 mm) on the
front edge. This will avoid damage to the carbon ber panel. Refer to image in 2.3
Track Extension.
CAUTION: The track extension should only be used during closed circuit track events.
The track extension can cause premature damage to your vehicle if used on public roads.
Regularly inspect the outboard knock-in threaded insert to avoid premature splitter wear
(right and left side). Replace these fasteners as needed in order to protect the carbon
ber splitter panel.
2.3 Standard Track Extension
A splitter track extension is shipped with every Viper ACR. The track extension is
mounted in the same location as the center rub strip. The on-track aerodynamic balance
was optimized with the track extension in place.
To install the track extension, remove the 14 screws from the center rub strip and install
the extension in the same mounting locations.
Tighten fasteners to 70 in-lb (7.9 N·m).

2.3.1 Extreme Track Extension
To install the track extension, follow these steps:
1. Use hardware provided to install extension struts to the track
extension (see gure 1) and torque nuts to 70.81 in-lb (8 Nm).
Install track extension struts to track extension before installing
track extension to splitter.
2. Remove rubstrip from splitter panel and install track extension
(torque nuts to 70.81 in-lb [8 Nm]).
3. Remove bumper beam nut located behind the grille (see gure 2).
4. Insert bracket through top grille opening from the center of the car,
slide outboard to bumper beam stud location, rotate and place on
stud, and install nut. Torque to 425 in-lb (48Nm) (see gure 3).
5. Connect extension struts to the track extension brackets using
the pin on the strut.
6. Finally, Adjust the strut length to tighten the system.

edge before rotating top edge of the vent into place.
2. Once vents are installed, install both clips by securely holding rear
section of clip (1) and pushing nose of clip through bezel window
and opening (2).
NOTE: Ensure Center tongue (3) is securely inserted and engaged through
bezel window (Edge Highlighted In RED).
WARNING: Risk of loss or damage possible if vents and/or
clips are installed improperly.

2.6 Rear Wing
The ACR rear wing generates most of the car’s aerodynamic downforce.
The wing is a powerful element that will affect the handling of the car at speeds
greater than 50 mph. Extreme caution should be given to any modications to the
factory settings.
Regularly inspect the wing panel and attachment points for damage or looseness.
The Viper ACR on-track aerodynamics have been tuned and balanced for the vehicle
with the track extension installed.
Wing Stanchions
The wing stanchions are designed with adjustment capability but they are delivered
locked with tamper resistant fasteners.
For the Standard Viper ACR, the wing is delivered from the factory in hole position 4.
For the Extreme Viper ACR, the wing is delivered from the factory in hole position 2.
WARNING: Do not operate the vehicle with the rear wing removed.
Aerodynamic balance of the vehicle is unstable and can cause loss of control,
resulting in crash, injury and/or death.

Wing Adjustments
It is possible to adjust the wing using the hole pattern at the top front of
the stanchion.
NOTE: Adjustment to the wing setting is not recommended.
The wing is attached to the lower stanchions with thread locker and tamper
resistant fasteners.
In general, moving the wing up (e.g. Hole 2 to Hole 1) will decrease rear down
force and decrease overall grip and understeer.
Each successive hole increases the wing angle of attack by 1.5 degrees.

Extreme Diffuser Strake Extensions
NOTE: Installation of the diffuser strake extension may take up to 30min with a
power drill driver and a 8mm swivel socket.
Attach diffuser strake extensions (6) to inboard side of diffusers using provided
fasteners (28) and torque to 70.81 in-lb (8 Nm).
CAUTION: As strake extensions wear down, aerodynamics may be affected.
Replace as needed.
2.7 Extreme Diffuser Strake Extensions
NOTE: Diffuser Strake Extensions can be stored in the splitter extension bag
provided with the vehicle.

2.8 Carbon Fiber
The ACR aerodynamic components are made from prepreg autoclaved carbon ber. Both woven and
unidirectional materials are used.
The clear coated carbon ber panels will have some variation and minor waviness in the woven pattern. This is
inherent to the process and a sign of its authenticity.
All carbon ber materials are susceptible to UV degradation during long exposure to the sun. The ACR woven
carbon components use the latest technology for both the resin system and the clear coat. As with any
automotive coating, storing your vehicle in a covered location will guarantee a long lasting nish.

2.9 CCM Brake Duct Installation
To install the Brake Ducts, follow this procedure:
1. Slide handed brake duct onto the lower control arm, moving from center of
the car outward.
2. Ensure the brake duct snaps over the bolt already mounted to the lower
control arm.
3. Install the supplied ring clip around the shock uid line, snapping into the
hole on top of the brake duct.
NOTE: The tie strap included in the package, located in the trunk, can be used to
further secure the Brake Duct to the vehicle.

3.0 Carbon Ceramic Material Brake System (CCM) -
If Equipped
The Viper is known for having world class brakes. The 2016 Viper ACR
takes this incredible braking system to the next level with the Brembo
Carbon Ceramic Material brake system. This brake system signicantly
reduces the rotating un-sprung mass while increasing on-track fade
performance and long term durability.
It is normal for the brakes to make some popping or creaking noises as
they cool down. This is the result of the two-piece construction.
Although the CCM brake rotors are a two-piece construction, they
should be replaced as a complete assembly.
CAUTION: During brake pad replacement, install new wear indicator
sensors on the new pads (included in Mopar pad kit).
CAUTION: These rotors may also produce some additional brake noise
due to the high performance brake pads and two-piece construction.
