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).

{Warning
Do not touch heater or radiator hoses,
or other engine parts. They can be very
hot and can burn you. Do not run the
engine if there is a leak; all coolant could
leak out. That could cause an engine fire
and can burn you. Fix any leak before
driving the vehicle.
Caution
Do not use anything other than a mix of
DEX-COOL coolant that meets GM
Standard GMW3420 and clean, drinkable
water. Anything else can cause damage
to the engine cooling system and the
vehicle, which would not be covered by
the vehicle warranty.
Engine Coolant
See”Engine Coolant” under“Cooling
System” in the owner’s manual.
Engine Overheating
See“Engine Overheating” in the owner’s
manual.
Brakes
Due to California and Washington law, brake
service for some high-performance Camaros
manufactured after December 31, 2020,
cannot be conducted using GM original
equipment brake pads in those states.
Service requiring original equipment brake
pads can be performed at any GM
dealership in the remaining 48 states.
Otherwise, replacement of brake pads in
California or Washington will require
replacement of additional brake system
components. See your dealer to verify the
manufacture date for your vehicle.
Wheels and Tires
Low-Profile Tires
If the vehicle has 285/30ZR20,
305/30ZR20, 305/30ZR19, or 325/30ZR19
size tires, they are classified as
low-profile tires. Caution
Low-profile tires are more susceptible to
damage from road hazards or curb impact
than standard profile tires. Tire and/or
wheel assembly damage can occur when
coming into contact with road hazards
like potholes, or sharp edged objects,
or when sliding into a curb. The warranty
does not cover this type of damage. Keep
tires set to the correct inflation pressure
and when possible, avoid contact with
curbs, potholes, and other road hazards.
Competition Oriented Tires
This vehicle may come with 305/30ZR19 and
325/30ZR19 Goodyear Eagle F1 Supercar 3R
competition oriented tires that are DOT
approved for street use. Competition
oriented tires use a special tread pattern
and compound that provide more grip than
normal road tires. The minimum tread depth
will be reached earlier than typical tires,
resulting in reduced tire life. This special
tread pattern and compound will have
decreased performance in cold climates,
heavy rain, and standing water. It is
recommended that winter tires be installed

on the vehicle when driving at temperatures
below approximately 10 °C (50 °F) or on ice
or snow covered roads.
{Warning
Driving on wet roads, in heavy rain,
or through standing water with
competition oriented tires may cause
hydroplaning and loss of control. Use
extreme caution and drive slowly on wet
roads.
{Warning
Driving with competition oriented tires on
snow, ice, or cold road surfaces can cause
loss of control or a crash. Competition
oriented tires are summer season tires
and are not intended to be driven on
snow, ice, or road surfaces below 10 °C
(50 °F). Do not drive a vehicle with
competition oriented tires in these
conditions.
Caution
Competition oriented tires have rubber
compounds that lose flexibility and may
develop surface cracks in the tread area
at temperatures below−7 °C (20 °F).
Always store competition oriented tires
indoors and at temperatures above −7 °C
(20 °F) when not in use. If the tires have
been subjected to −7 °C (20 °F) or less, let
them warm up in a heated space to at
least 10 °C (50 °F) for 24 hours or more
before being installed or driving a vehicle
on which they are installed. Do not apply
heat or blow heated air directly on the
tires. Always inspect tires before use.
Summer Tires
High Performance Summer Tires
ZL1, SS with the 1LE package, and LS/LT with
the 1LE package are equipped with high
performance summer tires. These tires have
a special tread and compound that are
optimized for maximum dry and wet road
performance. This special tread and
compound will have decreased performance
in cold climates, and on ice and snow. It is
recommended that winter tires be installed
on the vehicle if frequent driving at
temperatures below approximately 5 °C
(40 °F) or on ice or snow covered roads is
expected. See “Winter Tires” in the owner’s
manual.

34 Vehicle Care
Caution
High performance summer tires have
rubber compounds that lose flexibility
and may develop surface cracks in the
tread area at temperatures below−7 °C
(20 °F). Always store high performance
summer tires indoors and at
temperatures above −7 °C (20 °F) when
not in use. If the tires have been
subjected to −7 °C (20 °F) or less, let them
warm up in a heated space to at least
5 °C (40 °F) for 24 hours or more before
being installed or driving a vehicle on
which they are installed. Do not apply
heat or blow heated air directly on the
tires. Always inspect tires before use. See
“Tire Inspection” in the owner’s manual.
Tire Pressure for High-Speed
Operation
{Warning
Driving at high speeds, 160 km/h
(100 mph) or higher, puts additional
strain on tires. Sustained high-speed
driving causes excessive heat buildup and
can cause sudden tire failure. This could
cause a crash, and you or others could be
killed. Some high-speed rated tires require
inflation pressure adjustment for
high-speed operation. When speed limits
and road conditions allow the vehicle to
be driven at high speeds, make sure the
tires are rated for high-speed operation,
are in excellent condition, and are set to
the correct cold tire inflation pressure for
the vehicle load. Vehicles with tire sizes listed in the High
Speed Operation Inflation Pressures table
require inflation pressure adjustment when
driving the vehicle at speeds of 160 km/h
(100 mph) or higher. Set the cold tire
inflation pressure to the corresponding value
in the table for the tire size on the vehicle.

wheel/tire. Use tire skates or dollies
under any locked wheel/tire while
loading the vehicle. Do not use a sling
type lift to tow the vehicle. This could
damage the vehicle.
Caution
Improper use of the tow eye can damage
the vehicle. If equipped, use the tow eye
to load a disabled vehicle onto a flatbed
tow truck from a flat road surface, or to
move the vehicle a short distance. Use
(Continued)

caution and low speeds. The transmission
must be in (N) Neutral when moving the
vehicle.
GM recommends a flatbed tow truck to
transport a disabled vehicle. Use ramps to
help reduce approach angles, if necessary.
A towed vehicle should have its drive wheels
off the ground. Contact Roadside Assistance
or a professional towing service if the
disabled vehicle must be towed.
To tow the vehicle behind another vehicle
for recreational purposes, such as behind a
motor home, see the owner’s manual.
