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.

18 Driving and Operating
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:

24 Driving and Operating
Competitive Driving Mode, PTM, and Launch
Control are systems designed for a closed
course race track and not intended for use
on public roads. The systems are not
intended to compensate for lack of driver
experience or familiarity with the race track.
Custom Launch Control may be available
through the Settings menu, if equipped. See
“Custom Launch Control”in Track Events and
Competitive Driving in the owner’s manual.
Limited-Slip Differential
The Electronic Limited-Slip Differential (eLSD)
is a hydraulically actuated clutch system.
It can infinitely vary the clutch engagement
between 0 and 2000 Y(1475 lb ft) of
breakaway torque between the rear wheels.
It responds to full engagement within
0.150 seconds when necessary. Smaller
clutch adjustments happen even faster.
The eLSD:
.Uses the vehicle sensors and driver inputs
to determine the optimum amount of
clutch engagement for the conditions.
.Improves traction while cornering by
changing the engagement to achieve a
balance between directional control and
acceleration.
.Provides optimal engagement for
high-speed control and stability without
affecting precise steering and turn-in.
.Improves vehicle stability during spirited
driving and evasive maneuvers. Is fully
integrated with the Active Handling and
Performance Traction Management (PTM)
systems.
There are unique calibrations based on the
Traction Control System (TCS) setting. eLSD
modes change automatically when
Yis
pressed. No unique input from the driver is
required.
.Mode 1 is the standard mode when the
vehicle is started. It provides a touring
calibration with an emphasis on vehicle
stability. Mode 1 is also used in PTM
Wet mode.
.Mode 2 is engaged when both TCS and
StabiliTrak/Electronic Stability Control
(ESC) are turned off. This calibration
provides more nimble corner turn-in, and
is biased for better traction out of
corners.
.Mode 3 is engaged when PTM is engaged
in Dry, Sport 1 & 2, and Race modes. This
is a nimble calibration with similar
functionality as eLSD Mode 2, however, it
is integrated to work with PTM.
.Mode 4 is engaged when TCS is selected
off, but StabiliTrak/ESC remains on.
Vehicle stability is still the priority, while
allowing for optimized traction out of
corners.
The ZL1 1LE, ZL1 coupe, and SS 1LE are
calibrated uniquely and optimized for their
unique powertrain and chassis combinations.
Fuel
Top Tier Fuel
GM recommends the use of TOP TIER
Detergent Gasoline to keep the engine clean,
reduce engine deposits, and maintain
optimal vehicle performance. Look for the
TOP TIER Logo or see www.toptiergas.com
for a list of TOP TIER Detergent Gasoline
marketers and applicable countries.

Driving and Operating 25
Recommended Fuel
Use premium unleaded gasoline meeting
ASTM specification D4814 with a posted
octane rating of 93—(R+M)/2.
If unavailable, unleaded gasoline with a
posted octane rating of 91 may be used, but
with reduced performance and fuel
economy. If the octane is less than 91, the
engine could be damaged and the repairs
would not be covered by the vehicle warranty. If heavy knocking is heard when
using gasoline rated at 93 octane, the
engine needs service.
Do not use any fuel labeled E85 or FlexFuel.
Do not use gasoline with ethanol levels
greater than 15% by volume.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:
.For vehicles that are not FlexFuel, fuel
labeled greater than 15% ethanol by
volume, such as mid-level ethanol
blends (16–50% ethanol), E85,
or FlexFuel.
.Fuel with any amount of methanol,
methylal, ferrocene, and aniline. These
fuels can corrode metal fuel system
parts or damage plastic and rubber
parts.
(Continued)
Caution (Continued)
.Fuel containing metals such as
methylcyclopentadienyl manganese
tricarbonyl (MMT), which can damage
the emissions control system and
spark plugs.
.Fuel with a posted octane rating of
less than the recommended fuel. Using
this fuel will lower fuel economy and
performance, and may decrease the
life of the emissions catalyst.

Vehicle Care 39
ZL1 1LE Spoiler
It is not recommended that the ZL1 1LE
spoiler be waxed, as it will change the gloss
level of the surface. In addition, care must
be used when waxing around the spoiler.
If a small amount of wax is applied to the
spoiler it can create an irregular appearance
to the surface of the panel. If wax, debris,
or other materials create stains on the
spoiler, see your dealer for the
recommended cleaner.
Fuel Spills
Wipe off fuel spills immediately to avoid
degrading the vinyl and adhesive. Then
wash, rinse, and dry.
