ROLL CENTER ADJUSTMENT
The roll center can be adjusted by adding or
removing shims from beneath the aluminum pivot
mounts.
LOWER ROLL CENTER
(INITIAL SETTING - NO SHIMS) will give more
traction and increase chassis roll.
HIGHER ROLL CENTER
(adding shims)
will increase steering by making
the car rotate more on and off-power.
IMPORTANT! Always use same shim thickness on
both sides of both aluminum holders.

PIVOT MOUNTING ALTERNATIVE
REARWARD:
Pivot mounted in rearward chassis holes, and 1mm shim
used under the pivot ball. The rearvard pivot mounting gives
the most neutral handling. Recommended for low to medium
traction tracks.
MIDDLE:
(INITIAL SETTING)
Pivot mounted in middle chassis holes, with 3mm shims
under the pivot ball. The middle pivot position gives a good
balance between front and rear traction and is well suited
for most conditions.
FORWARD:
Pivot mounted in forward chassis holes, with 5mm shims
under the pivot ball. improves rotation thanks to the longer
rear pod geometry. gives the most initial steering as well as
rotation, especially suited for high traction conditions such
as US black carpet.
Ensure free, smooth
movement.
Tighten the screw enough
to remove excess play, while
ensuring that the pod plate can
turn freely.
