ADJUSTING YOUR MODEL
Once you become familiar with driving your model, you might
need to make adjustments for better driving performance.
Adjusting the Toe-in
0
°
Geometry and alignment
specs play an important role
in your model's handling.
Take the time to set them
correctly. Turn off TSM (see
page 17); then, set the
steering trim on your transmitter to neutral. Now, adjust your servo and
tie rods so that both wheels are pointing straight ahead and are parallel
to each other (0° toe-in). This will ensure the same amount of steering in
both directions. For increased stability, add one- to two-degrees of toe
in to each front wheel. Use the turnbuckles to adjust the alignment.
Adjusting the Camber
-1
°
The camber angle of both
the front and rear wheels can
be adjusted with the camber
rods (upper turnbuckles).
Use a square or right-angle
triangle to set the camber
accurately. The stock camber
-1.5
°
of the front wheels is -1
degree of camber. In the
rear, the stock camber is -1.5
degrees. These adjustments
should be set with the truck
positioned at its normal ride
height with a battery installed.
Fine Tuning the Shocks
The four shocks on the model greatly influence its handling.
Whenever you rebuild your shocks or make any changes to the
pistons, springs, or oil, always make changes to them in pairs (front
or rear). Piston selection depends on the range of oil viscosities
that you have available. For example, using a two-hole piston with
a lightweight oil will, at one point, give you the same damping
as a three-hole piston with heavier oil. We recommend using the
two-hole pistons with a range of oil viscosities from 10W to 50W
(available from your hobby shop). The thinner viscosity oils (30W or
less) flow more smoothly and are more consistent, while thicker oils
provide more damping. From the factory, the shocks are filled
with SAE-30W silicone oil. Use only 100%
pure silicone shock oil to prolong seal life.
The model's ride height can be adjusted
by adding or removing the clip-on, spring
0
°
preload spacers. Adjust the ride height so
that the suspension arms are slightly above
being parallel to the ground. Observe how
the model handles in turns. Proper setup
will add stability and help prevent spin outs.
Toe-in
Experiment with different springs and shock
oils to find what works best for your current
track conditions.
Shock Mounting Positions
Big bumps and rough terrain require a softer
suspension with the maximum possible
suspension travel and ride height. Racing
-1
°
on a prepared track or on-road use requires a lower ride height and
firmer, more progressive suspension settings. The more progressive
suspension settings help reduce body roll (increased roll stiffness),
dive during braking, and squat during acceleration.
Front Camber
Your model's suspension can be altered to perform well in a variety
of terrain conditions. By making simple changes to the shock
-1.5
°
positions, you can alter the handling of
the vehicle.
For off-road driving:
1. Place the front shocks in the
Rear Camber
inner hole (position 1) on the
suspension arms.
2. Place the rear shocks in position 2
on the suspension arms.
For on-road/hard-packed surface driving:
1. Place the front shocks in the
outer hole (position 2) on the
suspension arms.
2. Place the rear shocks in the
middle position (position 3)
on the suspension arms.
These settings are suggested starting
points. Experiment with the shock
positions to find the best setup for your
terrain, traction level, and driving style.

All of the toe links are installed
on the truck so the left-hand
thread indicators point to the
same direction. This makes it
easier to remember which way
to turn the wrench to increase
or decrease toe link length
(the direction is the same at
all four corners). Note that the
groove in the hex indicates the
side of the toe link with the
left-hand threads.
