Adding caster to Bowden front suspension

 A theory dictates that high speed stability would be enhanced if the steering had some caster, typically about 6 deg. This was reasonably easily done by inserting a wedge at the mounting point of the front suspension (on the cassis) and extending the lower wish bones to take up the change in dimensions. The wedge was fashioned in a milling machine using 8mm alloy plate and putting a 6 deg slope on the part.

The other item on the list is the lower wishbones that need to be extended.

A jack screw was added to the lower suspension arms to extend them.

The final test was on the track see Video
