Setting the shock absorbers

The spring elements of the all-wheel suspension of the chassis consist each of a
coil spring in whose center and oil dampened suspension is located.
The eight oil-dampened shock absorbers, two on each side at the front and the
back, are mounted on the lower transverse links and at the top on the damper
plate on the differential housings. On the top, the coil springs rest against a screw
ring (3) on the outer tube of the shock absorber and a plate on the bottom end of
the piston rod. The spring travel of the piston rods is limited by silicone sleeves
on the lower part of the piston rods.
Turning the screw ring towards the top relieves the spring.
Turning it downward increases the spring preload.
The spring preload can thus be finely adjusted according to surface and manner
of driving. A low spring preload makes the chassis sink deeper under its own
weight, while a harder setting lifts the chassis up. In this way, a certain higher or
lower position of the chassis can be achieved (setting ground clearance).
The setting of the suspension influences not only the ability of the model to "even out" road unevenness, but also the behavior in bends.
This driving behavior is called to "oversteer" or to "understeer".
Over-steering or under-steering driving behaviour can be the result of uneven cornering powers of front and rear axle due to incorrect setting of the
camber.
Understeering driving behavior:
The model is difficult to steer around the bend, "pushes" the front wheels outwards (too much traction of the
rear axle or too little traction of the steered front axle.
As a counter measure the suspension should be set harder at the rear (or softer at the front).
Over-steering driving behavior
The model "pulls" in the bend, the rear tends to swerve (too little traction on the rear axle or too much traction at the steered front axle).
As a counter measure the suspension should be set softer at the rear (or harder at the front).
Over-steering or under-steering driving behaviour can be the result of uneven cornering powers of front and rear axle due to incorrect setting of the
camber.
As a basic setting, the front axle should be set approximately 5 mm lower than the rear axle!
Check the impact of the shock absorbers:
- Lift the model at the rear axle and drop it.
- The model should not deflect until lock and only top out once without any
reverberation!
- Test the shock absorbers of the front axle in the same way.
Setting the spring preload
- Increasing the spring preload
Turn the screw ring on the outer tube of the shock absorber clockwise.
- Decreasing the spring preload
Turn the screw ring on the outer tube of the shock absorber anticlockwise.
Tuning
The oil used in the shock absorbers of the X-Factor is perfectly suited for most applications. By selecting the right shock absorber oil, you can influ-
ence the shock absorbing characteristics.
On generally even ground, we recommend using a more viscous oil (high viscosity), on rough terrain, however, you should use a low-viscosity oil.
Do not use any engine oil. We generally recommend using pure silicon shock absorber oil only.
To further optimize the damper characteristics, we offer, in our accessories, silicon oil for the shock absorbers in different visco-
sities!
