Why isn't the engine compartment in the model?
I think I'd need to see this to see where the loads are going to go.
If you tie the windscreen frame structurally it'll make a huge difference to the torsional stiffness too.

Yes, sorry about the windshield frame. It's not determined where the best place to tie it in would be. Any suggestions for that? down to the
outside frame rail, or down to the inside framerail?....
The engine compartment is a few days out design-wise.

In your last drawing, your car isn't an open top anymore.
Did I miss something?
Why did you trash the previous design?

What? That little central cage structure? Why, that's nothing. You won't even be able to see it.... 
Well actually.... A significant increase in stiffness and safety were the two major factors. Of course the two hoops can be deleted if one desires
more sedate open top motoring.
I have taken what I felt were weaknesses in the original design and am trying to find improvements. Lighter weight and stiffer structure with a
significant increase in safety due to the integral rollcage structure. You will note that my body design has no doors. So then no reason to run the
upper rail at only 11", instead move it up to 20" where it can significantly improve the torsional stiffness of the chassis. Almost all of
the chassis structure is hidden underneath the bodywork anyways.
