Upper Arm Position Adjustment Shims

The shims influence the camber gain change.

MORE shims = less camber gain, reduced initial
steering, reduced steering sensitivity (less twitchy).

LESS shims = more camber gain, increased initial
steering, increased steering sensitivity.

eccentric (optional). Use the same bushing in front and rear, and
also use the same orientation of the bushing on both right and left

FACTORY PRE-ASSEMBLED

Add oil in each slot of the Derlin™ side shock tubes.

OIL

NOTE: Add oil only in the slots, not on the whole tube.
After assembling the side tubes, check for smooth operation.

NOTE: It is very important to re-oil the side tubes, as least once per race day.
NOTE: You may use different oil thicknesses depending on track conditions.

The angle of the side tubes has a fine effect on car
performance. The higher the angle, the stiffer it feels and
the less it rolls. The less (flatter) the angle, the softer it feels
and the more it rolls.

completely. Fill the shock
body with the shock oil.

Move the shock shaft up and
down a few times to release
the air bubbles trapped
beneath the piston.

Orient the filled shock
vertically for several
minutes with the shock
shaft fully extended. The
remaining air bubbles will
release.

Install the shock membrane
into the groove in the
upper shock cap.

Gently place the shock cap
assembly onto the filled
shock body. Excess oil will
spill from the shock. Screw
the shock cap onto the body
by only a few turns, approx.
50%. Excess oil will flow
through the hole in the
shock cap.

Gently push the shock shaft
completely into the shock
body. Excess oil will flow
through the hole in the
shock cap.

100%

➐

Keep the shock shaft
pushed in the shock body
and tighten the shock cap
completely.

Tighten the cap fully but
do not overtighten or the
rubber membrane may be
damaged. Make sure that
there is no oil leakage
after the cap is tightened.

ALTERNATIVE 1
SHORT SHOCK (REARWARD POSITION)

An innovative new feature is to change the center shock
front mounting position & shock length. By moving the
center shock mounts on the chassis to either the forward or
rearward position, the damping and steering characteristics
can be changed.

REARWARD shock position (SHORT shock):
Improved steering response, quicker direction changes.

FORWARD shock position (LONGER shock with adapter):
Improved driveability over bumps, improved on-power
traction.

DOWNSTOP ADJUSTMENT

The length of the shock absorber affects the amount of
rear downstop. To adjust, thread the ball-joint on or off the
bottom spring cap or adapter.

ALTERNATIVE 2 (INITIAL SETTING)
LONG SHOCK (FORWARD POSITION)

For the long shock
alternative, the shock
adaptor must be used.

Inline battery alignment improves cornering speed and reduces the chance that
the rear of the car will „diff out.“ Recommended for high-traction conditions.

Cross-chassis alignment provides more neutral handling, making the car less sensitive to set-up

conditions.
