If equipped with the Z51 package,
the racing and competitive driving
wheel alignment settings should be
set as follows:
{Caution
Using these wheel alignment
settings may cause excessive tire
wear. Only use these wheel
alignment settings for racing or
competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.
Alignment should only be done by
adjusting the lower control arm cam
bolts and not by removing the
washers between the upper control
arms and frame.

.Camber: -2.0 degrees
.Toe: 0.05 degrees toe in REAR (per corner)
.Caster: 0 degrees
.Camber: -1.7 degrees
.Toe: 0.05 degrees toe in

Because the fluid temperatures may
be higher, it is necessary to change
the rear axle fluid every 24 hours of
track events or competitive driving.
See Recommended Fluids and
Lubricants on page 11-12 for what
fluid to use.
{Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty.
Do not drive as long or as fast the
first time the vehicle is driven on
the track or raced. If reduced performance is
experienced during track events or
competitive driving, turning off the
A/C will help to improve engine
performance.
Maintain a mixture of 40%
DEX-COOL coolant and 60% clean,
drinkable water to optimize engine
performance.
The front license bracket or aero
panel should be removed for track
events and competitive driving to
improve engine performance.
Rotor Cooling Ring
{Caution
Do not leave rotor cooling rings
installed after a track event, as
this can cause corrosion with
long-term use. Rotor cooling rings
are for race track use only. Race
track driving without the rotor
cooling rings may result in brake
pedal fade.

9-8 Driving and Operating
Installation:
1. Remove the front wheels.
2. Cut three 150 mm (6 in) lengthsof safety wire specified to T304
Stainless Steel, 0.041 in nominal
diameter, not included.
3. Form each into a U shape with a 20 mm (0.75 in) flat area in the
center of the wire.
4. Place the rotor ring in the gap between the rotor brake plate
and rotor hat, with the holes on
each side of the rotor spoke on
the outboard side of the rotor.
5. Place the U-shaped wire through
the holes in the rotor
cooling ring.
6. Bring the ends of the wire tight around the corresponding rotor
spoke.
7. Twist the safety wire into six to eight twists per inch.
8. Bend the twisted wire so it is flush with the inside of the rotor
ring to prevent contact with the
caliper or brake hoses. 9. Verify that the rotor rings and
safety wire do not contact any
other components.
10. Reinstall the wheel using the specific lug nut torque. See
Capacities and Specifications
on page 12-2.
If additional brake cooling is
required, the grille mesh in the lower
corners of the front grille in front of
the brake duct can be removed.
This is not reversible, and a
replacement grille will not be
covered by the warranty. If this is
done, it is recommended that the
gap between the fascia and the
cooling duct be taped over.
Brake Burnishing
New brake pads must be burnished
before racing or other competitive
driving.

Driving and Operating 9-9
{Caution
The brake burnish procedure is
specific to the Z51 brake package
and should not be run on other
models as damage may result.
{Caution
The new vehicle break-in period
should be completed before
performing the brake burnish
procedure or damage may occur
to the powertrain/engine. See
New Vehicle Break-In on
page 9-18.
When this procedure is performed
as instructed, it will not damage the
brakes. The brake pads will smoke
and produce an odor. The braking
force and pedal travel may increase.
After the procedure, the brake pads
may appear white at the rotor
contact. Perform this procedure only on dry
pavement and in a safe manner and
in compliance with all local and
state ordinances/laws regarding
motor vehicle operation.
Racing/Track Brake Burnish
Procedure
{Caution
Brake pedal fade will occur during
this track burnish procedure and
can cause brake pedal travel and
force to increase. This could
extend stopping distance until the
brakes are fully burnished.
1. Apply the brakes 25 times starting at 100 km/h (60 mph) to
50 km/h (30 mph) while
decelerating at 0.4 g. This is a
medium brake application. Drive
for at least 1 km (0.6 mi)
between applying the brakes.
This first step may be skipped if
there are more than 320 km
(200 mi) on the brake pads. 2. Repeatedly apply the brakes
from 100 km/h (60 mph) to
25 km/h (15 mph) while
decelerating at 0.8 g. This is a
hard brake application, without
activating the Antilock Brake
System (ABS). Drive for at least
1 km (0.6 mi) between stops.
Repeat until the brake pedal
travel starts to increase.
Depending on conditions, this
should take no longer than
25 brake applications.
3. Cool down: Drive at 100 km/h (60 mph) for approximately
15 km (10 mi) without using the
brakes.
4. Apply the brakes 25 times from 100 km/h (60 mph) to 50 km/h
(30 mph) while decelerating at
0.4 g. This is a medium brake
application. Drive for at least
1 km (0.6 mi) between
applications.

10-64 Vehicle Care
Tightening Wheel Lug Nuts
{Warning
Never use oil or grease on studs
or the threads of the wheel nuts.
The wheel nuts might come loose
and the wheel could fall off,
causing a crash.
{Warning
Incorrect wheel nuts or improperly
tightened wheel nuts can cause
the wheel to become loose and
even come off. This could lead to
a crash. Be sure to use the
correct wheel nuts. If you have to
replace them, be sure to get new
GM original equipment
wheel nuts.
{Caution
Improperly tightened wheel nuts
can lead to brake pulsation and
rotor damage. To avoid expensive
brake repairs, evenly tighten the
wheel nuts in the proper
sequence and to the proper
torque specification.
Tighten the wheel lug nuts firmly in
a crisscross sequence. See
Capacities and Specifications on
page 12-2.
Tire Chains
{Warning
Do not use tire chains. There is
not enough clearance. Tire chains
used on a vehicle without the
proper amount of clearance can
cause damage to the brakes,
suspension, or other vehicle
parts. The area damaged by the
tire chains could cause loss of
control and a crash. Use another
type of traction device only if its
manufacturer recommends it for
the vehicle's tire size combination
and road conditions. Follow that
manufacturer's instructions. To
avoid vehicle damage, drive
slowly and readjust or remove the
traction device if it contacts the
vehicle. Do not spin the wheels.
If traction devices are used, install
them on the rear tires.
