Eclipse4 Manual

Parallel front wheels or a slight Toe-out (up to 1 degree per side) is our
suggested setting range.
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.
The most important factor in racing is to get the tyres right. Contact foam tyres are designed for use on carpet tracks.
Shore hardness
28 30 32 35 40
Softer = more grip Harder = less grip
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.
RACERS TIP
43mm Rear, 41.5mm 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 (CR522 or MR-Superglue) 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.

First work out the gear ratio from the spur gear and pinion (For example 76/40 = 1.9).
Then complete the following equation.
