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.

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).
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.
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:
