I've found a set of wheels, that have the following specs:

 

19x8,5 ET43 cb66,6

 

As far as fitment goes I find them spot on, apart from the center bore.

 

Which leads me to the topics title, I've never used spigot rings and I'm trying to decide wether it could be problematic or not, I assume some people here are running them, so their feedback would be welcomed. 

 

Finally I'm not sure what would be better, having metal ones or plastic ones....

 

Thanks in advance for your any help.

When I bought the RS6 winter wheels from LDPrestige they came with the plastic type spigots which I ran for a few months with no trouble, I then saw some Ali ones on EBay so decided to buy them as an alternative, as they were not expensive.

Never had any trouble with either of them.

Its quite common for wheel manufacturers to make there wheels with a one size centre bore & then supply spigot rings to suit the application.

Plastic spigot rings work ok & won't seize onto the axle spigot unlike metal/alloy one's can.

To assist the spigot rings to do their job by keeping the wheel hub-centric, I'd suggest using wheel lugs with floating washers - wobble bolts.

 

And remember, the seat of the lugs on these new wheels will probably be conical, so do not use the oem wobble bolts.

Thanks Hal, in fact the wheels are OEM, but from an A6, so I’ll be using the original bolts which I think are floating.

My main concern is the eternal debate between those who think that the hub takes part of the load of the car or those who state that only the bolts and the friction take loads.

And depending on which line you choose, metal ones seem more aprpiate.

There's no eternal debate about what takes the load as the fact is the spigot takes the load & the bolts just hold the wheels in place.

I know of an incident where Sierra Cosworth wheels were fitted to a mk2 escort,same wheel stud pattern but slightly bigger spigot size & the wheel stud sheared off !

As for the material used for resizing the bore hole I'll use whatever the wheel manufacturer supplyed as I'm sure they know more about it then we will ever know.

Aftermarket wheels normally have a 45' seat face were vag use a conical seat face mate.

mmm. Not too sure about that! I think you will find that Audi generally has ball seat with R13 (Mercedes uses R14 - easy to mix, and often done), generally aftermarket wheels use 60 degree cone and aftermarket light truck could be 90 degrees...

I don’t have things that clear, hence I find it difficult to see a plastic spigot taking that load, I’m no expert on the mechanical properties of thermoplastic, but I don’t see it taking that load.

Danw 8V has plastic spigot rings fitted in his aftermarket wheels & goes to France at least twice a year fully loaded up with his fishing gear doing 80+mph with no problems.

I've inspected them recently when i removed his rear wheels to fit a RS7 rear discs conversation & saw not visible damage/wear.

I'm sure there's other's on here with aftermarket wheels with plastic spigot rings fitted & they don't think twice about it.

The bottom line is if your not comfortable about that set up fit metal one's.

I have to disagree with you here. Look at most truck wheels and a lot of cars for that matter. The trucks have a  lot more weight and a lot more shear load on the bolts. Not a spigot in sight. The bolts are purely there to provide a clamping load to hold the wheel against the hub and have no part in transmitting the torque. If it was possible to press the wheel against the hub hard enough to give the same clamping load as the wheel bolts then you wouldn`t need any bolts at all. The spigot whatever it is made of just centralizes the wheel. Take modern engine design. The cams and even the cranks just have a single central bolt holding the pulleys on to provide the clamping load. No keyways,no dowels no tapers.

In the case of the Cossie overtightening the bolts is THE main cause of studs shearing off.

Sorry I've got the terminology round the wrong way 🙄

I did mean the oem wheels have a ball type seating & aftermarket one's normally use as you rightly corrected me have a 60' taper 👍

Cheers mate you learn something new every day 👍

In that case it don't matter if you fit plastic or metal spigot rings.

Or veneered wood. Job for Sean maybe ?

I could make you some fancy plywood versions

Or even plywood wheels.

Sean can do wonders with wood so if you want to go organic I'm sure he would obliged mate.😂

Might get some wooden pads and discs to stop the brake squeal
