TRACK SETTINGS
ROLL SPRINGS See Page 6 - Step 5
Roll springs are used to control the cars steeing balance. A softer spring
will give an easier to drive car. Stiffer roll springs can be used to give a
more aggressive car. The standard setting has the roll springs
uncompressed and both just touching the lower pod plate when the car is
stationary. Screwing them downward and compressing the springs
creates more steering while loosening them gives an easier to drive car.
Adjusting the springs allows the tweak to be infinitely adjusted. Ensure
they are not set too unevenly. If more than 0.5mm different, further
investigation is required.
REAR BUMP SPRING See Page 5 - Step 4b
This spring is used to set the pod angle of the car. Adjust the spring
tension so that the pod is horizontal when the car is on a flat surface.
A softer bump spring will give a more aggressive car entering the corner,
but offers more grip mid corner and on corner exit. It will also improve the
cars bump handling.
RIDE HEIGHT & CASTOR
- Increasing spacer ‘C’ increases ride height.
- Changing spacer ‘D’ doesn’t affect ride height.
- Increasing spacer ‘C’ or ‘D’ decreases droop.
Spacer C
Spacer D
(Kit)
*One Black King Pin Spacer = 0.25mm
Use the eccentrics to adjust the rear ride height. Raising the axle lowers
the ride height. Lowering the axle raises the ride height.
The recommended ride height is 3.5mm on carpet.
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. Ride Height

FRONT TOE
CAMBER See Page 8 - Step 8
Parallel front wheels or a slight toe out (up to 1 degree per side) is the
recommended setting.
Toe out gives more initial steering. It does however make the car more
difficult to drive on the straight, due to increased responsiveness.
Increasing the negative camber angle will increase the cars steering. This
will make the car more difficult to drive but often faster on a lap.
Reducing the negative camber angle is a good setting change if traction
roll is a problem.
As a general rule, setting the camber so that the tyres wear without any
coning will give the most ideal setting in usual conditions.
TYRES See Page 14 - Step 14
The most important factor in racing is to get the tyres right. Contact foam tyres are designed for use
on carpet tracks.
Toe out
Negative Camber
Use softer front tyres if you want more steering, and harder front tyres if you want less steering.
In high traction conditions sometimes you can have too much overall grip. Using harder tyres all
round should make you faster through the corners with less traction rolling in these conditions.
If the track grip is not high enough, or the tyres are too hard, the car may slide and stop in the
corners, if this is the case, reduce the shore rating until the track conditions change.
RACE TIP - 41.5mm rear, 40.5mm front is a good all round tyre size, reducing this size is only
an advantage in extreme conditions to prevent grip roll. If you have too much steering then add
a thin layer of superglue (CORE Racing #CR522) to the outside edge of the front tyre to reduce
the front tyre grip. This can be used to prevent grip roll in extreme conditions.
REAR ROLL DAMPING See Page 11 - Step 11
Generally, in high traction conditions, thinner roll damping oil is better.
Low traction tracks may require thicker damping.
Thicker roll damping oil slows the weight transfer of the rear and makes
the car easier to drive. Thicker oil can help if the track surface is bumpy
and there are issues with bumps in the middle of the corner.
A good range is between 7,000cSt and 20,000cSt.

POD ANGLE AND HEIGHT
REAR DROOP See Page 4 - Step 3 and 4a
When X= 4.3mm, the pod angle is 0°. This respresents the kit setting.
This gives best support for the rear roll springs and set the kit motor height.
If this number is decreased, the motor height will drop below the chassis, and be the
ride height limitation. It is generally not best to do this, except in ultra high traction,
where lifting the chassis may also be benefitial.
This can be be adjusted in small measures to quickly change ride height, however, it
should not exceed less than 3.7mm and more than 4.8mm. Droop must be adjusted after
this is done.
Rear droop adjusts the balance of the cars handling. Less droop makes the car
more aggressive, squaring up the turns. More droop gives less corner rotation
but an easier to drive car. More droop also improves the cars bump handling.
Start with 1mm of droop.
To set this, start with the droop screw fully screwed in and back it out to reduce
droop. Measure this by measuring the cars rear ride height, then take all the
weight off the car by lifting from the rear of the centre damper tube (the wheels
must still just be touching the floor). Measure the chassis from the floor in this
position and subtract the ride height to calculate droop
REAR BUMP DAMPING See Page 11 - Step 11
Generally, in high traction conditions, thinner bump damping oil is better.
Low traction tracks may require thicker damping.
Thicker bump damping oil slows the weight transfer of the rear and
makes the car easier to drive when coming off power. Thicker oil can help
if the track surface is bumpy and there are issues with bumps when the
car is moving in a straight line.
A good range is betweeen 15,000cSt and 50,000cSt.
LIPO POSITION See Page 2 - Step 1
Moving the LiPo forward will make the car smoother and easier to drive.
Moving the LiPo rearward will make the car more aggressive and provide more steering. It may help prevent rear wheel lifting
when traction is very high.
See Page 5 - Step 4b
X
Increasing Front Droop will make the car more agressive and have more front grip.
Decreasing Front Droop makes the car smoother and easier, at the expense of rotation.
Front droop is adjusted in 0.25mm steps using the shims on the kingpin.
They can be positioned above or below the hub carrier but please note that if placed
above the hub carrier, the ride height will be decreased. Shims below will not change the
height of the car, only the droop.
Kit setting 2 shims on both kingpins.
