Super REIB

Take a look at this rear sus of the new SSC car.

Are those REIB on a 1350HP car?

Please share with us what you see that you like about this sub-assemblies. I am curious.

Well I love those red wheels.

I would have some questions for them:
Is the upper a-arm load path and the rod end a permant set up?
How does the ARB attach to the lower a-arm?
Is part of the transmission sticking out past the crush structure?

But without better pics (more angles) I don't want to criticize their design.
These are the only others they've posted:

I hope the Good Lord has mercy on the 'engineer' who designed this!

Notice the bolts; it looks like it puts the low a-arm into bending.

The upper a-arm load path is really scary.

On one hand, they're putting 1350 horsepower through this, somehow, and haven't crashed it heavily enough to warrant a redesign yet. In addition, a lot of street car manufacturers swear by (rather than at) longitudinal compliance, and this design seems to offer plenty.

On the other hand, that is an absolutely hideous toe-control link setup with a pair of load paths that look like spaghetti. I cannot get my eye off that upper arm and the link out by the wheel that I'm not entirely sure what to call. Surely having a tube that goes through the upright rather than a pair of welded-on tabs might help with the whole "not falling off the car at two hundred miles per hour" thing?

I am mystified by what structure supports the top of the coil shocks.
They just appear to sit there in clear open space attached to nothing.

And there appear to be two very long and loose bolts fitted into the upper corner tabs of the rear hoop.

Could this be a very early mock up rather than the final completed vehicle ?
That could explain much.

@jd74914
Most road car ARBs put the lower control arm in bending.
But at a node and farther out.

@Charles Kaneb
Not only 200mph but on up to ~270mph

@Warpspeed
I'm gonna guess they attach to the rest of hte chassis.
I think a rolling mock up (maybe even slow driving) is a reasonable bet.

You can clearly see the rose joints at the top of the coil shocks with a loose bolt, and no structure anywhere near there to bolt it to.

Not even a rolling vehicle I would say.

With that somewhat important structure completely missing, it would IMHO be unfair to assume that what we are looking at is anything like how it finally ends up.

Here are some more pictures, but they don't really show more of this very special design:
