TUNING
GUIDE
When tuning the Evader EXT2, make sure that you have
equal-length shocks, camber rods and steering rods on both
sides (left and right). They do not have to be the same front
to rear.
CASTER
Caster refers to the angle of the kingpin in relation to the
surface when viewed from the side. 0° of caster means that
the kingpin is straight up and down. The Evader EXT2 comes
stock with 30° of caster and is not adjustable.
CAMBER
2° 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° 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 TOE-IN AND TOE-OUT
1°
1° Toe-In
Front wheels pointed towards each other.
Toe-in and toe-out refer to the angle which the tire is at
when viewed from above. Toe-in increases stability under
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° of toe-in.

WHEELBASE
Wheelbase is the distance from the center of the front wheel
to the center of the rear wheel. Lengthening the wheelbase
of the Evader EXT2 increases steering, but decreases rear
traction as a result of increased weight distribution to the
front wheels. Decreasing the wheelbase of the Evader EXT2
will increase rear traction, but decrease steering.

Rear
Traction
The battery placement of the Evader can be adjusted with
the foam spacers which will affect the truck's rear traction.
Moving the battery forward will create less rear traction, but
more steering. Moving the battery to the rear will create more
rear traction, but less steering.
CAMBER LINK PLACEMENT
The camber link placement affects the traction and handling
on rough tracks. Using a long mounting position will increase
traction but decrease stability. Shortening the link will increase
stability, but decrease traction.
