what is the OD and ID of those things btw? I guessed about 57mm od and used a penny diameter for the id (9.05mm)
^That can be tweaked before production but mine are .51000000"ID x 1.60000000"OD x .5000000" thick.
That should be plenty of land for any wheel to clamp on.
Here is an install picture.
You can see the adaptors bolted on with the studs sticking out then the spacers on the studs and finally the wheel and nuts.:biglaugh:
Between the spacers you can see the head of the Audi bolts securing the adaptors.
We don’t need no stinking hub rings.:pimp:
in that case, 40 g/cc 
I just weighed one on our super sensative scale.
39.9 grams. (chamfers):biglaugh:
lol right on :tup:
Is this something that you’ve seen done or are you pioneering this?
I ask, because I am unfamiliar with using individual spacers like this on wheels.
May be great, but they look scary.
Pioneering.
They are only spacers there is no force other than clamping.
They actually allow more air flow for cooling too.
the only thing I’d be worried about is “possible” reduced contact area, but I’m sure it’s somewhat of a moot point.
AWD, why not a universal unit with slots instead of holes? (4 lug and 5 lug versions)
These are done in one simple lathe op with little material.
To machine “rings” would require 2 lathe ops and a mill op.
Unless of course you have a $500,000 water jet.
lol enough said
Oh yeah, and a saw op from bar stock.
in the case of hitting a bump, most of the stress will be on an individual stud instead of distributed across the whole wheel hub…
will this cause the stud to snap now that it has exponentially more stress on it?
that’s the question. it might work, but I’d be scared – mostly because i’ve never seen anybody do this.
so are the pretty snug on the studs then? or do they fit a bit loose? I would think if they didn’t fit snugly over, and they were sitting a bit off center, that it would throw everything out of balance.
I made them to fit my studs nicely but that little movement with that little weight that close to center won’t mean a thing.
If you have 30+lbs of tire at 23", 40 grams at 4" off by a few thousandths won’t matter.
Hell I bet if you threw a steel one in the mix you wouldn’t be able to tell.
hmm, I see what you’re saying. I would try a pair.
How difficult is it to swap wheel studs?
It depends on the car.
The Evo was super easy.
Finding the longer studs took longer than changing them.
In fact I bought 2 sets just for good measure.:biglaugh:
depends on the vehicle. Generally not more then a few minutes per wheel.
no need to saw, shove the bar stock down the throat and part that shit off. wow thats kinky 
Eh, you’d think.
