Driving Information
Track Events and Competitive
Driving
{Danger
High-performance features are intended
for use only on closed tracks by
experienced and qualified drivers and
should not be used on public roads.
High-speed driving, aggressive cornering,
hard braking, and other high-performance
driving can be dangerous. Improper driver
inputs for the conditions may result in
loss of control of the vehicle, which could
injure or kill you or others. Always drive
safely.
This section covers specific track events and
competitive driving information for the
Camaro High Performance models only. For
additional track events and competitive
driving information, see the owner’s manual. Track events or competitive driving may
affect the vehicle warranty. See the
warranty manual before using the vehicle
for racing or other competitive driving.
The Engine Sound Management setting
should not be set to Stealth Mode during
track events and competitive driving. See
“Driver Mode Control”
in the owner’s
manual.
{Warning
Prior to each track event and again
before returning to public roads, tighten
the wheel nuts with a torque wrench to
the proper torque specification. Wheel
nuts that are improperly or incorrectly
tightened can cause the wheels to
become loose or come off, resulting in a
crash. See “Capacities and Specifications”
in the owner’s manual for wheel nut
torque specifications.

Engine OilCaution
If you use the vehicle for racing or other
competitive driving, the engine may use
more oil than it would with normal use.
Low oil levels can damage the engine. For
information on how to add oil, see
Engine Oil028.
Be sure to check the oil level often during
racing or other competitive driving and
keep the level at or near the upper mark
that shows the proper operating range on
the engine oil dipstick. The LT1 and LT4 engines are factory filled
with 0W-40 dexos2 oil. 0W-40 dexos2
engine oil is approved for both track and
street use with the LT1 and LT4 (ZL1 only,
not ZL1 1LE) engines. 15W-50 full synthetic
engine oil may also be used for track use
and is required on the ZL1 1LE, but after
track use must be changed back to 0W-40
dexos2 for street use. See
Capacities and
Specifications 043.
Fuel
Consider using 100 octane unleaded gasoline
if the air temperature is above 30 °C (86 °F)
at a track event. Do not use any fuel with
conditions listed in Prohibited Fuels025.
Automatic Transmission Fluid
Transmission fluid should be changed after
every 15 hours of track use. Any
transmission level set or change should be
performed at your dealer.
Manual Transmission Fluid
Manual transmission fluid should be
changed after every 15 hours of track usage.
Tire Pressures
Tire pressure specifications are listed
in psi (kPa). Limit the vehicle weight to a
maximum of the driver and one passenger,
with no additional cargo.

Front License Plate/Bracket Removal
(ZL1 Only)
For track use, the front license plate and
bracket can be removed from the fascia for
increased airflow. Remove the license plate
to access the four screws that attach the
license plate bracket to the front fascia.
Water Deflector
If operating a ZL1 on a closed course in hot
temperatures, remove the water deflector to
increase airflow and improve cooling.
Remove the three bolts. Replace
immediately after track use to protect the
engine compartment from water intrusion.
Torque to 4.5Y(40 lb in).
Wicker Bill
A rear spoiler wicker bill is available for
LS/LT and SS with the 1LE package only.
If equipped with a wicker bill, use the
instructions for installation.
Underbody Air Deflector Tire Dam Kit
The underbody air deflector tire dam kit
provided with ZL1 vehicles reduces the
amount of aerodynamic lift on the front
axle for better handling. The original tire
dams must be reinstalled after the track
event. For installation, see the instructions
provided with the kit.

Supplemental Power Steering Deflectors
The supplementary power steering
deflectors, if equipped, provide additional
cooling to the power steering gear during
track events. Remove the noise shields and
install the deflectors as directed by the
enclosed instruction sheet. Remove the
deflectors and reinstall the noise shields
immediately after track use to protect the
engine compartment from additional water
intrusion.
Adjustable Front Struts (ZL1 1LE Only)
Camber Position for Track Events
The front strut top mount can be positioned
two ways. The original setting is in the
street position, but it can be turned 180° to
the track position for additional negative
camber on the front.To adjust the position:
1. Raise the vehicle so the tires are slightly off the ground.
2. From the bottom side of the strut topmount, remove the Allen bolt that
secures the top mount alignment pin to
the top mount.
3. Remove the three strut mount bolts andthe alignment pin.

4. Using the hex feature on the top of themount, turn the top mount 180° until
the TRACK CAMBER text is visible and the
second set of top mount holes aligns
with the strut tower holes.
5. Reinstall the top mount bolts and torque to 29 Y(21.4 lb ft).
6. Keep the top mount alignment pin and bolt for reinstallation when the struts
are returned to the street position
following the track event.
7. Verify and adjust the vehicle alignment per track alignment specifications to
optimize vehicle performance for the
track event. 8. Verify and re-adjust the vehicle
alignment as needed following the track
event.
Strut Spring Seat Adjustment
The front struts have a threaded spring seat
that allows adjustment of the preload on
the front springs. The vehicle corner weights
and front trim heights can be adjusted.
The spring seat can be adjusted
approximately 10 mm (0.4 in) up or down
from the nominal position. Each complete
turn of the spring perch will change the
vehicle height approximately 1.4 mm
(0.06 in). Do not allow the spring seat to
contact the black seal cap when adjusting in
the maximum upward direction.
To adjust the lower spring seat: 1. Raise the vehicle so the tires are completely off the ground.2. Loosen the lower spring seat bolt. Donot completely remove the bolt.
3. Turn the spring perch upward to increase spring preload, or downward to decrease
spring preload.
4. Torque the spring seat bolt to 10 Y
(7.4 lb ft).
5. Verify and adjust the vehicle alignment as needed following the spring seat
adjustment.

Adjustable Rear Stabilizer Bar
(ZL1 1LE Only)
The rear stabilizer bar ends have three
attachment positions that allow the rear roll
stiffness of the vehicle to be adjusted.The stabilizer bar stiffness increases
approximately 15% using the rearward holes,
or decreases approximately 10% using the
forward holes.
To change the attachment position:
1. Raise and support the rear of the vehicle.
2. Remove the stabilizer bar link nut while holding the ball stud end.
3. Reposition the stabilizer bar link stud to the desired hole and tighten to 43 Y
(32 lb ft). Use the same hole position for
both sides of the vehicle.
Wheel Alignment
Track alignment specifications are for vehicle
at curb weight conditions (full tank of fuel,
zero ballast).
Racing and competitive driving wheel
alignment settings can be set as follows for
increased handling performance:
