Wheel adapters - track safe?

Drill the wheels?

Kinda OT:

Steering wheel WILL shake over 100 kph when wheels spigot diameter > hub diameter without rings.

Many cars, many times, sometimes more, sometime less but good spigot rings will be needed if there is difference in hub/spigot diameter.

No it won't, steering wheel will shake if your tyres/wheels aren't properly balanced. I've been running wheels without spigot rings for years, if properly balanced there won't be ANY shake.

The issue is more about safety than wheels shaking.

Just one example of many.

Yes it will, wheel is out of axis by mm or two.
But, i agree to disagree

I can't believe that has something to do with spigotrings.
At the moment your wheelnuts are torqued to the correct level, there is no real stress on the bolts/studs, as all of the force is 'transmitted' through the hub by the clamping force (i don't know how to put this correctly in english) and not on the bolts/studs.

Looking at this pic...



... it appears that the wrong studs were used, as there is
clear evidence that the thread went all the way thru the rotor.
Studs of the correct type have smooth shank inside the thickness
of the rotor, with a larger diameter. The thread does not start until
the stud is a small distance outside the rotor.

Most likely the studs were not correctly torqued for the new
larger diameter wheels, and this allowed the wheel or rotor to
move on the hub. The studs were then subject to bending forces
that caused a fatigue failure, probably originating in the root of
the first thread.

Hub centric rings would not have prevented this failure. The interweb
is full of misinformation and psuedoscience promulgated by people
who take as gospel the BS put out by other people who want to sell
their products to a gullible public.

The AE86 came from the factory with hubcentric wheels and shank
and washer type lug nuts. This is the absolute best wheel and nut
design without question. However, if non-hubcentric wheels and cone
faced nuts were as dangerous as some people make out, they would
be used in warfare instead of bullets

and in a track / competition environment nothing less should suffice.
Cone face nuts were used by Toyota on AE86 steel rims.
