178 Driving and Operating
Electric Power Steering
The vehicle has electric power steering.
It does not have power steering fluid.
Regular maintenance is not required.
If power steering assist is lost due to a
system malfunction, the vehicle can be
steered, but may require increased effort.
If the steering assist is used for an extended
period of time while the vehicle is not
moving, power assist may be reduced.
If the steering wheel is turned until it
reaches the maximum rotation and is held
at that position for an extended period of
time, power steering assist may be reduced.Normal use of the power steering assist
should return when the system cools down.
See your dealer if there is a problem.
Dynamic Rack Travel
If equipped with Magnetic Ride Control,
Dynamic Rack Travel (DRT) is a steering
system feature which enhances driving by
providing additional maximum steering
wheel rotation to allow a tighter turning
radius during low speed driving conditions.
If the vehicle speed increases or if the
suspension encounters significant wheel
travel, such as a driveway, while at
maximum steering rotation, DRT may gently
push the steering back a small amount to
prevent the front tires from contacting the
vehicle. This is normal operation. There is no
customer interface or display for this
feature. DRT is not available when in
Track Mode.
Curve Tips
.Take curves at a reasonable speed.
.Reduce speed before entering a curve.
.Maintain a reasonable and steady speed
through the curve.
.Wait until the vehicle is out of the curve
before accelerating gently into the
straightaway.
Steering in Emergencies
.There are some situations when steering
around a problem may be more effective
than braking.
.Holding both sides of the steering wheel
allows you to turn 180 degrees without
removing a hand.
.The Antilock Brake System (ABS) allows
steering while braking.
Off-Road Recovery

Driving and Operating 179
The vehicle's right wheels can drop off the
edge of a road onto the shoulder while
driving. Follow these tips:1. Ease off the accelerator and then, if there is nothing in the way, steer the
vehicle so that it straddles the edge of
the pavement.
2. Turn the steering wheel about one-eighth of a turn, until the right front
tire contacts the pavement edge.
3. Turn the steering wheel to go straight down the roadway.
Loss of Control
Skidding
There are three types of skids that
correspond to the vehicle's three control
systems:
.Braking Skid —wheels are not rolling.
.Steering or Cornering Skid —too much
speed or steering in a curve causes tires
to slip and lose cornering force.
.Acceleration Skid —too much throttle
causes the driving wheels to spin. Defensive drivers avoid most skids by taking
reasonable care suited to existing conditions,
and by not overdriving those conditions. But
skids are always possible.
If the vehicle starts to slide, follow these
suggestions:
.Ease your foot off the accelerator pedal
and steer the way you want the vehicle
to go. The vehicle may straighten out. Be
ready for a second skid if it occurs.
.Slow down and adjust your driving
according to weather conditions. Stopping
distance can be longer and vehicle control
can be affected when traction is reduced
by water, snow, ice, gravel, or other
material on the road. Learn to recognize
warning clues
—such as enough water,
ice, or packed snow on the road to make
a mirrored surface —and slow down
when you have any doubt.
.Try to avoid sudden steering, acceleration,
or braking, including reducing vehicle
speed by shifting to a lower gear. Any
sudden changes could cause the tires to
slide.
Remember: Antilock brakes help avoid only
the braking skid.
Track Events and Competitive
Driving (Z51 Only)
Vehicles without Z51 package should not be
used for 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.
Participating in track events or other
competitive driving without following the
instructions provided may affect the vehicle
warranty. See the warranty manual before
using the vehicle for racing or other
competitive driving. See Competitive Driving
Mode 0214.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14622938) - 2021 - CRC - 9/22/20
182 Driving and Operating
The driver should immediately start a cool
down lap if on the track. If this message
displays, take the vehicle to be serviced at
your dealer.
Brake Burnishing
New brake pads must be burnished before
racing or other competitive driving.
Caution
Performing the brake burnish procedure
on a base brake system can result in
brake damage.
Caution
The new vehicle break-in period should be
completed before performing the brake
burnish procedure, otherwise damage
may occur to the powertrain/engine. See
New Vehicle Break-In0190.
Caution
Brake pedal fade will occur during any
track burnish procedure and can cause
brake pedal travel and force to increase.
This could extend stopping distance until
the brakes are fully burnished. 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, in a safe manner, and in
compliance with all local and state
ordinances/laws regarding motor vehicle
operation.
Brake Burnishing Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
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. Apply the brakes 25 times starting at 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 applications.
Depending on conditions, some increase
in brake pedal travel and brake pedal
force may be experienced.
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.
As with all high performance brake systems,
some amount of brake squeal is normal.
Alternative Closed Course Brake Burnishing
Procedure
This brake burnish procedure should only be
run on vehicles with the J55 Z51 factory
equipped brake system.
This procedure should only be run on a
track and only on dry pavement. 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.

14622938) - 2021 - CRC - 9/22/20
Driving and Operating 183
1. Start track lapping at lower speeds andlower braking efforts for three minutes
of driving. Allow for increased braking
distances due to reduced brake output.
2. After Step 1, increase speed and braking effort for the next six minutes of
lapping, gradually ending up at 90%
effort. Continue to allow for increased
braking distance due to reduced brake
output.
3. Cool the brakes by lapping with minimal light braking for six minutes.
Brake Cooling Kit
Prior to any track event, high speed driving
event, or competitive driving, the following
should be completed:
.Ensure all brake cooling parts are
correctly and securely installed.
.Install the rear lower control arm cooling
ducts per the instructions below also
included with the kit. After any track
event or competitive driving, remove the
rear lower control arm cooling ducts.
These parts are for track use only.
Removing the ducts helps prevent debris
from being channeled into the rear brakes
during regular use of the vehicle.
.Inspect for and remove any blockage in
the ducts.
.Inspect and replace any duct that has
damage.

Shock Spring Seat Adjustment
The front shocks, on vehicles without
hydraulic front lift and rear shocks, have
threaded spring seats that allow adjustment
of the preload on the coil springs. The
vehicle corner weights can be adjusted for
track use. If the vehicle trim height is
modified, it should be returned to normal
trim height before street use.

Chevrolet Corvette Owner Manual (GMNA-Localizing-U.S./Canada/Mexico-
14622938) - 2021 - CRC - 9/22/20
184 Driving and Operating
The spring seat can be adjusted
approximately 20 mm (0.8 in) up or down
from the nominal position. Each complete
turn of the spring seat will change the
vehicle height approximately 1.5 mm
(0.06 in). When adjusting the seat to the
upper limit, lift the dust boot and ensure
the seat does not thread off the center
support tube (stop adjustment when threads
no longer visible). When adjusting the seat
to the lower limit, leave approximately
10 mm (0.4 in) of thread visible for the
lower lock nut to have full thread
engagement.
The following procedure can be complex and
should only be performed by trained
personnel. See your dealer.
To adjust the lower spring seat:1. Raise the vehicle so the tires are completely off the ground.
Front Shown, Rear Similar
2. Loosen the lower spring seat lock nut (2).
3. Thread the lower spring seat lock nut (2) downward off of the threads to its
resting location on the shoulder of the
center support tube.
4. While holding the center support tube holes, turn the spring seat (1) upward to
increase spring preload, or downward to
decrease spring preload.
5. Thread the lower lock nut (2) back on to the center support tube and torque it
against the spring seat (1) to 25 Y
(18.4 lb ft).
Load Limit
Limit vehicle load to the driver only, with no
other cargo. Inflate the front tires to 159 kPa
(23 psi) and the rear tires to 165 kPa (24 psi).
Drive at a maximum speed of 296 km/h
(184 mph).
Road Course target hot pressures of
220–240 kPa (32–35 psi). Value will vary
based on driving style, track, temperature,
and weather conditions.
Wheel Alignment
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.
