WHEELBASE ADJUSTMENT
The RC10GT wheelbase can be
changed easily to allow further fine tuning of
your truck for different track conditions. This
can be accomplished by moving the 1/8”
(3.17mm) plastic spacer on the rear outer
hinge pin (next to the rear hub carrier). If the
spacer is located in front of the rear hub
carrier, it will lengthen the wheelbase and
increase steering. If the spacer is located in
the rear of the rear hub carriers (which is
the stock position) it shortens the wheel-
base and give more rear traction.
CAMBER LINK ADJUSTMENT
Changing the mounting position of the
camber links can affect traction, stability,
and handling on rough tracks. Use the fol-
lowing guidelines to try and find the correct
handling for your track conditions.
Using a longer mounting position will in-
crease traction but decrease stability and
rough track handling.
Using a shorter mounting position will
decrease traction but increase stability and
rough track handling.
RIDE HEIGHT
Now we check the ride height of your
RC10GT to make sure the settings are cor-
rect. Before we make this adjustment we
should have the truck ready to race (mean-
ing fully loaded with fuel and receiver batter-
ies), but leave off the body.
For the front, push down on the front
suspension and then let go. When the sus-
pension stops, the front arms should be level
with the bottom of the chassis kick up. If
not, you can make adjustments by using
the shock preload clips that come in your
kit.
Now push down on the back suspen-
sion and let go. The axle driveshafts should
be level. Look at the rear end photo to com-
pare. You can make the adjustment by us-
ing the shock pre-load clips that come in
your kit.
Adjust ride height by add-
ing or subtracting clip-on
preload spacer #6475.
SHOCK SPRINGS
Springs are to keep your car level during acceleration , decel-
eration, and cornering. Stiffer springs will help your suspension
respond more quickly, but because of their stiffness will not ab-
sorb bumps as well. Use stiffer springs in high traction conditions.
Softer springs are best for slippery or bumpy conditions.

GEARING
The RC10GT features the ability to change the
gear ratio. The drive reduction of the GT gearbox is
2.60 to 1. Use the following formula to calculate the
final drive ratio:
# Spur gear teeth
———————— x 2.60 = final drive ratio
# Clutch bell teeth
Your RC10GT come stock with a 66 tooth spur gear and a 15 tooth clutch
bell. This combination will provide the best overall performance for most tracks.
Here is a chart showing you different ratios (includes our optional clutch bells):
