FRONT CAMBER ANGLE SETTING
-
+
Negative
Positive
Place the model car on flat surface. Raise the chassis to it's maximum clearance
before the wheels leave the ground.
Adjust the length of the front and rear upper arms so that the wheels are right angle to the
ground.
The camber angle adjustment can be moving the turnbuckle rod on the upper arms,
clockwise or anti-clockwise.
(We suggest use zero degree for the front and 1.5 negative degree for the rear.)
FRONT TOE-IN AND TOE-OUT SETTING
NEUTRAL POSITION
TOE-OUT
Adjust the length of front steering rod to change the
toe angle.
Making the tie rod longer will make the front tires
become toe-in.
Response will be slower and will over steer.
Making the tie rod shorter will make the front tires
become toe-out.
Response will be quicker and will under steer.
CASTER ANGLE
Adjust the front caster angle by changing the arm block "A" or "B" on the front lower arms.
After you set the caster angle , you will also need to adjust the front upper arm position.
The final caster also depends on the kick-up setting.
Example:15 degree caster on C-hub + 7degree kick-up+"A" lower arm block =22 degree final caster.
15 degree caster on C-hub + 7degree kick-up+"B" lower arm block =20 degree final caster
15 degree
on C hub
7 degree
Caster angle
Increases off-power steering into a corner.
Less caster
Decreases on-power steering out of and in a corner.
Decreases straight-line stability.
Decreases off-power steering into a corner.
More caster
Increases on-power steering out of and in a corner.
Increases straight-line stability.

FRONT SHOCK ANGLE SETTING
Firm front suspension, less steering.
Soft front suspension, more steering.
REAR SHOCK ANGLE SETTING
Firm rear suspension, over steering.

Adjust the wheelbase by using the spacers on either side of the rear uprights (at the bottom pin).
IMPORTANT! Make equal adjustments on both left and right sides of the car.
Shorter wheelbase
less spacers in front of the rear upright.
- increases rearward weight transfer during acceleration.
- increases on-power traction.
- quicker off-power steering into corners.
- slight tendency to push on-power at corner exit.
- increases steering response.
- better on tighter, more technical tracks.
Longer wheelbase
more spacers in front of the rear upright.
- decreases off-power steering into sharp corners.
- increases stability.
- slower initial steering reaction (off-power).
- improves on-power steering at corner exit.
- better handling over bumps and ruts.
- better on more open tracks with high-speed corners.
