TRACK SETTINGS
RIDE HEIGHT
Use the spring spacers on the shock absorbers to adjust the front and
rear ride heights. With the car level, we recommend setting the ride
height to around 19mm on astro, 23mm on dirt and 14-16mm on carpet.
(16mm if there are large jumps in the track).
This is measured between the bottom of the chassis and the ground with
the car in running trim. First press the car down on to the ground and
release it once or twice to settle the suspension before adjusting the ride
height. The chassis should be level when viewed from the side.
Adjusting the spring collars does not increase or decrease the spring
stiffness only the preload.
If the suspension needs to be softer or harder change the spring.
FRONT TOE
Front toe should be set to 0° (both front wheels pointing straight
ahead) this will be the best setting for most track conditions. Adding
toe out will increase initial turn in and make it smoother to drive on
power. The team generally run 1° toe out on Astro tracks.

FRONT WISHBONE SHOCK MOUNTING HOLE
Hole (2) on the wishbone is the standard setting for most
tracks. Moving the shock to the inner hole makes the car
more reactive. It increases the initial turn in and makes the
front of the car roll more through the turns. This setting also
makes the front end softer. Moving the shock outboard to
position 3 will stiffen the front end and reduce the body roll.
Note that position 4 is used for the front Anti-Roll bar drop link.

REAR WISHBONE SHOCK MOUNTING HOLE
Hole 3 works best for most track conditions giving good traction and
drive through the turns whilst maintaining good stability over the
bumps. Moving to the outer hole on the wishbone will decrease
traction but will allow the rear to free up more in the turns. This
setting would usually only get used on high grip tracks and when
moving the shock out you may have to change the oil and spring
settings to get the same suspension feel. If the grip level is low and
the track is bumpy, try moving the mounting hole inboards,
alongside harder springs and thicker oil. This should help improve
the handling.
