The front suspension parts were updated
to eliminate play to ensure better steering
performance. The updated holes in the
steering blocks may cause a tighter fit
on the king pin; it is important that the
steering block moves freely but without
excessive play. If the king pin does not
insert into the steering block easily, use
a 4mm Arm Reamer to enlarge the hole.
Be very careful to remove only enough
material so you can insert the kingpin
without a lot of force.

SOFTER SPRINGS
Makes the car easier to drive over bumps and
increases steering as it makes the car roll more,
especially in the middle of a corner.
HARDER SPRINGS
Makes the car more responsive and increases initial
steering. Recommended for high-traction and flat
tracks.
MORE DROOP
will make the car initially less responsive, but it will give the car more front grip,
especially in the middle of the corner. The car will be less precise and more difficult to drive, because of
increased roll. More droop is best suited for low- to medium-traction carpet, or asphalt.
LESS DROOP
will decrease roll but the car will change direction quicker. Less droop is best suited
for high-traction surfaces such as US black carpet, especially when traction rolling is an issue (and
particularly when a rear solid axle is used).
FRONT DROOP
Front droop is adjusted by the preload of the front spring.
More shims between the steering block and the spring will
increase preload - and decrease droop. Fewer shims will
decrease preload and increase droop.

FRONT DAMPING with different oils.
TRACK CONDITIONS
Thinner oil is recommended for low-traction
tracks, while thicker oil is recommended for
high-traction tracks.
DAMPING
Using thicker oil on the king pin axle makes
the car less responsive but easier to drive.
Thicker oil oil also increases stability but
decreases cornering speed.
LOW traction & bumpy track
7K ~ 10K cSt
HIGH traction & smooth track
15K ~ 30K cSt
The thickness of the shims used
affects the ride height and
droop of the front suspension, so
determine the proper amount
of shims based on tire diameter
and desired droop.
RIDE HEIGHT AND DROOP ADJUSTMENT SHIMS:
Ride height is adjusted with the supplied long shims (silver, black,
gold) that can be placed under the arms. I recommend using
the lowest possible ride height, unless the track surface is very
bumpy or rough. In that case, the car can benefit from having a
slightly higher ride height which will help to increase stability and
improve handling over bumps.
The front axle height can be adjusted with shims under the
steering block. You cannot change the roll center at the front
of the X10’22 because there is no upper arm. Adding shims
under the steering block – which raises the steering block – will
raise the front axle height, and at the same time will decrease
bump steer. Removing shims will lower the steering block and
increase bump steer. For more information about Ackermann &
Bumpsteer, see PAGE 23 (servo mounting).
I recommend using the kit shimming for the front steering block
as a good basic setting for most conditions.
