Here is a drawing for a single seat car for a motorcycle engine. It has dual a-arms front and back. Have a look and give me some criticism on the overall machine.

Hard to critique because I really like what I see there!

that looks a little like the one I'm building right now.....

That looks great!

I have done a few more design changes, I think the lines flow a lot better.

better

Overall I like your design. It looks pretty well thought out.
I think I'd like to see your b-pillar move back behind the seat.
Plus, if you do that, you can run a cross bar to mount your harnesses, and you can come off of the pillar for your rear shock mount.

OK.
I played with the pics a little. What do you think?

That won't work I'm using dual a-arms, this will be better.

You're right, I wasn't thinking rear a-arm. You do want your shocks fairly perpendicular to the a-arms at mid travel. You may want the tops of the shocks a little inboard relative to the bottom. Are you planning on single or double a-arms for the rear?
