Digital Caster/Camber Gauge
ADJUSTING THE
QuickSet™
TO YOUR RIMS: Unfold the lower arms until they stop. To adjust
the feet to your rim: Hold against the rim with the gauge at approximately spindle centerline.
Select one of the threaded holes on the lower arms that is closest to the outer lip of your rim.
Move both feet to these holes and hand tighten. Now loosen the upper foot and slide it up until
it also touches the outer lip of your rim. Hand tighten. At this point
QuickSet™
should just fit
inside the outer lip of your rim with very little clearance.
1) Find a level place to set up your front end. This unit reads camber and caster very accurately.
Unlevel ground will affect that accuracy.
2) Hold the
QuickSet™
against the wheel and rotate the gauge until the small vial on the top
of the gauge shows level.
BE SURE WHEELS ARE POINTED STRAIGHT AHEAD WHEN SETTING CAMBER.
3) CAMBER: Turn on the
AccuLevel™
Digital Readout by pushing “
ON/OFF
”
. Camber is
read directly on the display to .1
O
(1/10
O
). See separate
AccuLevel™
instructions if
needed. On the left side of the display a pointing up indicates negative camber (top of tire
in). A pointing down indicates positive camber (top of tire out). Race cars usually use nega-
tive camber on the RF and positive camber on the LF.
4) CASTER is measured with the
AccuLevel™
. First turn the wheels 15
O
to the right when
setting the RF or 15
O
left when setting LF. Rotate the gauge until level. The 15
O
must be done
accuretely. An error of even 1 or 2
O
turning will give a caster error.
5) Turn on the
AccuLevel™
and push CASTER, then ZERO. The display will ‘flash’. Now
turn the wheels back past center to 15
O
the opposite way - for a total of 30
O
. Rotate the gauge
again to level. Read the Caster directly on the
AccuLevel™
to 1/10
O
.
CASTER NOTE:
This amount of sweep - 15
O
- is different from vial type gauges.
6) Adjust the caster and camber as needed. Each time you make a change bounce on the front
end to settle the suspension. NOTE: Adjusting the caster may have an effect on the camber and
vice versa. Tighten bolts & double check
all settings.

Warning:
Do Not leave the gauge in the hot sunlite
or store in a place over 120
O
F. The digi-
tal display may not be readable.
Once it cools down the digital display should be visable again.
Replacements for broken vials can be ordered from any autho-
rized dealer or the factory. Replacement is quick and simple with
no loss of accuracy.
