Gravity race car suspension parameters

[motorsportsdesign]

I am considering building a gravity racer and I wonder if ot is better to have suspesion or not?

How would I determine the optimum weight?

Any suggestions for steering geometry parameters? Caster, Camber, trail, scub radius etc.

As heavy as possible.

As little suspension travel commensurate with retaining control.

No scrub radius, no camber.

Cheers
