This looks a lot better than the other version.

Thanks, like I said, it's transforming into something closer to the final idea.

Another update. Looking much more car like now. Can see how the front end is coming together.

What is the purpose of the hoop within the front subframe? Will it be connected at the front end to the subframe?

It will be connected. As well as that's the rough location of drivers feet amd pedal assembly. So there a little extra protection and mounting surface there.

I love the update but what is the weight distribution going to end up as. There doesn't seem to be much in the front to offset the weight of that engine.

There isn't, unfortunately it will be quite rear heavy. I'm considering moving as much as I can up towards the front, ie. Battery, possibly fuel, anything else.

Update. More bracing added. Shock towers starting to come together. Its clearer now how its going to look different than many Locost and similar build which often use inboard suspension.

Couple of pics of the updated shock towers under construction.

The last towers locations posted weren't exactly in an ideal location, as I'm looking to replicate the stock Miata tower locations.

Thanks. Definitely not the first time its been called crazy, won't be the last.

I'm hoping I can get it out for at least one autocross or HPDE this year.

Looking good.

How do you install/remove the engine with it caged in like that?

It's stuck for ever.

You can vaguely see tube clamps at each end of the upper tubes. Similar to these :

I saw that but then for some reason assumed they were both slip in joints and was like... how is that going to come apart.
