d) Setting the Shock Absorbers
Figure 13: Front axle
Figure 14: Rear axle
The spring-pre-tension at the upper end of the shock absorber can be adjusted by inserting plastics clips.
The shock absorbers at the vehicle's front and rear vehicle axles can be mounted in different positions at the lower
transverse link (C) and at the top of the damper bridge (B). The manufacturer has, however, already chosen the best
position; therefore, only professional drivers should change these.
Always set the shock absorbers for one axle evenly (at the left and right wheels of the front or rear axle). Otherwise,
driving behaviour will be influenced negatively.
Professional drivers may also use springs with a different stiffness or damper oil of a different viscosity for filling the
shock absorbers. Installation of aluminium shock absorbers that can be adjusted with a knurled wheel is possible as
well.
Just as with a "real" car, the shock absorbers (or the rubber seals in them) on the model car are a wearing part. If oil
is running from the shock absorbers (e.g. transverse link strongly oiled, dripping traces), the seals or shock absorbers
must be replaced.
e) Mechanical Lowering
For lowering the chassis, it is also possible to reduce
the rebound clearance mechanically. There is a small
adjustable grub screw in each of the 4 transverse
links; see circle (A) in the figure on the right.
When the grub screw is turned in further, the trans-
verse link cannot extend as far anymore; this lowers
the chassis.
