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.

RIDE HEIGHT ADJUSTMENT

INITIAL SETTING

 above upper arm (1.9mm)
 below steering block (2.5mm)

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.
