Advice on structure of suspension mounting?

[N₂Onsense]

I am down to the last few supports I need for my go-kart with its swing arm setup. I have installed the hinge mechanism but now I have come up with a few ways to approach mounting the shocks on this thing. I would like recommendations and suggestions as to why each one will/will not work or what would need to be improved? Anything is welcome. (Again with the wack sketching)

Option #1
...seems like it has better engineering

1 is better but neither one will hold up very well, cuz....
that steering support hoop is not secure.
Continue the green "braces" to the front steering hoop and beyond, angled down to the frame. That makes your steering hoop stronger, more capable of taking the pounding from the rear suspension.
When ya build something like this, think triangles. Triangles are the stronges form.. Tringulate! Triangulate!Triangulate!

Keep on going, it needs front suspension too and that Predator 670cc V-twin for power.

Use my blue lines. Also add some up to the nose too.
Im trying to incorporate something non leg interferencing.

Wtr is right but he tends to under build.
l ran this by our engineering department and they suggested this:

you'll need to upgrade to a V8 but ther rest is purdy simple.
