b) Adjusting the shock absorbers
The spring elements of the all-wheel suspension of the chassis consists
of a coil spring each with an oil-pressure shock absorber in the center.
The oil pressure shock absorbers are fastened at the lower transverse
links and on top at the damper bridge on the differential housing. On the
top, the coil springs rest against a knurled nut on the outer tube of the
shock absorber and the spring attachment 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.
Twisting the knurled nut upwards relieves the spring. Twisting downwards
increases the pre-tension of the spring. The spring preload can thus be
finely adjusted according to surface and manner of driving.
The spring preload can thus be finely adjusted according to surface and
manner of driving.
• A low spring pre-tension lets the chassis sink lower due to its inherent
of a coil spring each with an oil-pressure shock absorber in the center.

• A low spring pre-tension lets the chassis sink lower due to its inherent
weight.
• A harder setting lifts the chassis.
In this way, a certain higher or lower position of the chassis can be achieved (setting ground clearance). The suspension setting affects the model's ability to
"even out" road unevenness as well as the models behaviour in curves.
This is driving behaviour is called to oversteer or to understeer.
Oversteering driving behaviour
The model "pulls" into the curve, the rear tends to swerve (too little traction on the rear axle or too much traction on the steered front axle).
As a counter measure the suspension should be set softer at the rear (or harder at the front).
Understeering driving behaviour
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 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 approx.. 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.
• 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 knurled nuts on the outer tube of the shock absorber clockwise.
• Decreasing the spring preload Turn the knurled nuts on the outer tube of the shock absorber counter-clockwise.
• Increasing the spring preload Turn the knurled nuts on the outer tube of the shock absorber clockwise.
• Decreasing the spring preload Turn the knurled nuts on the outer tube of the shock absorber counter-clockwise.
