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 ZLE 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.

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 thestrut top mount, remove the
Allen bolt that secures the top
mount alignment pin to the top
mount.3. Remove the three strut mountbolts and the alignment pin.

4. Using the hex feature on thetop of the mount, 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 dust boot 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 seatbolt. Do not completely remove
the bolt.

3. Turn the spring perch upwardto increase spring preload,
or downward to decrease
spring preload.
4. Torque the spring seat bolt to 10Y (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.
