TRACK SETTINGS
RIDE HEIGHT
Use the spring adjusters 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.
REAR TOE
The base setting for rear toe in is 3°, this is a good compromise between forward
traction and the car binding in the turns. This setting is fine for most tracks. You
can alter the toe in by adding/removing washers behind the rear suspension
mount. If you are running too much toe in, your car may suffer from instability at
high speeds. Decreasing the toe in will reduce forward traction but will free the car
up in the turns. Usually the team use less toe in on high grip tracks and more for
low grip tracks.
A good starting position is 1.5° on carpet and 4.0° on low grip dirt and wet astro.
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
The outboard 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.
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 hole 4 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 the holes 1 and 2 with harder springs and thicker oil.
This should help improve the handling.
