With rocker A-arms the coilovers could be inside the body.
What about weight distribution (50/50 or biased to the rear)? Rear brakes only? Up on jacks how long will the wheels spin? Does high or low rotating mass have the advantage?
There's a minimum wheelbase but no maximum. A longer wheelbase would allow a recumbent position and better fineness ratio.

Hi Freebeard,
this line is not defined, is only to explain the "safe area" created by the rollbar in case of rollover.
The top contenders are the sejkora soapboxes and they are open wheeled:
but this year they implemented a kind of front "wing" whit a curved endplates to reduce wheel drag:
the rear suspension is already a pushrod system, now i have to upgrade the front.
i use a tail heavy car, because it has more potential energy.
the wheel now spins for 5 min.
Low rotating mass is better, lower inertia = better acceleration=better braking.
Thank you
