TUNING GUIDE

When tuning the Evader ST Pro make sure that you have
equal length shocks on both sides (left and right), camber
rods and steering rods. Also, make sure to have the shock
pre-load adjusters at the same setting from left to right. They
do not have to be the same front to rear.

CASTER

Caster refers to the angle which the kingpin is at in relation to
the surface when viewed from the side. 0 degrees of caster
means that the kingpin is straight up and down. The Evader
comes stock with 30 degrees of caster and is not adjustable.

CAMBER

2º Negative Camber
Camber refers to the angle at which the tire and wheel ride in
relation to the ground when viewed from the front or rear.
Negative camber is when the tire and wheel lean inward and
positive camber is when the tire and wheel lean outward.Typically
you want 0 to 2 degrees of negative camber. Never put in positive
camber. Make sure that both sides have equal amounts of
camber by keeping the camber turnbuckles equal in length.

FRONT/REAR TOE-IN AND TOE-OUT

acceleration. However, toe-in also decreases steering when
entering a corner. Toe-out will increase steering into corners,
but will decrease the overall stability during acceleration. The
front typically is set-up with 0 to -2 degrees of toe-in.
0˚ Toe-in
Rear toe-in affects the traction of both the front and rear of
the truck. Rear toe-in increases the amount of traction in the
rear, but decreases steering. Decreasing rear toe-in will
increase steering, but will give less rear traction. Notice that
placing the rear suspension arm mount screws in different
locations on the aluminum rear plate changes the rear toe-in.

REAR ANTI-SQUAT

1˚ Anti-squat
2˚ Anti-squat
3˚ Anti-squat
Increasing rear anti-squat will increase traction and give you
more on-power stability. However, the truck will have less grip
when decelerating into a corner. This could cause the truck to
spin out entering the corner. More anti-squat allows the truck
to accelerate better through the rough parts of the track.

WHEEL BASE

Long
Two Washers
In Front
Wheel base is the distance from the center of the front wheel
to the center of the rear wheel. Lengthening the wheel base
of the Evader increases steering, but decreases rear traction
as a result of increased weight distribution to the front
wheels. Decreasing the wheel base of the Evader will
increase rear traction, but decrease steering.
