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.
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 (Stingray Z51)
Limit vehicle load to the driver only, with no
other cargo. Inflate the front tires to 160 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 are
220–240 kPa (32–35 psi). Value will vary
based on driving style, track, temperature,
and weather conditions. See Tire Pressure for
High-Speed Operation 0279 for high speed
non-track use.
Load Limit (Z06)
Tracks with Combined High-Speed and
High-Load Corners
(e.g., Nurburgring Nordschliefe, Spa
Francorchamps, or similar)
Limit the vehicle to the driver and one
passenger, with no additional cargo.
