Caster and the effects on steering return
Positive A positive caster will allow the wheels to return to center when the steering wheel is released

Main “rack” will need to be accross across the top, and transfer the rotation at the ends of the steering arms using some kind of vertical shaft? Similar to how catamaran boats steer.

Good equations
Theta = ArcTan( Wheelbase / (turning radius - track/2))
Note that the turning radius is not shown in the diagram below but you can imagine it being the arc along which the centreline of the car must travel. This number needs to be adjusted so that the outer wheel will travel along the maximum allowed radius. That is to say, (turning radius + wheelTrack/2) < max allowed radius.
(7m outer radius used for msxii, regs say 8.5m -> 6m inner radius, + 5m wide lane = 8.5m middle arch)
theta is the inside wheel turning angle, otherwise known as maximum turning angle
To do
Transfer written notes to confluence
document key equations
determine mock track and wheel base dimensions
link to google drive of any solidworks sketches etc.
