Spigot Rings

[alexmccabe]

I've never bought any before, I am wondering what people have. I would prefer aluminium, unless someone says anything different. They're to go on a new set of Mercedes wheels.

I have been looking at these: http://www.ebay.co.uk/itm/360831279149?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

Thanks guys :)

Iv always used plastic ones. Never had a problem with them

[George10]

I've also only used plastic ones. Cheaper and do exactly the same job.

^ exactly what those guys said.

I had alloy ones, one scored my hub and the other seized to it.
Go for plastic. They are not weight bearing anyway... they're only to center the wheel.

I beg to differ.... 

[xjay1337]

They're not. Once the wheel is bolted up the entire load is maintained on the hub face with the bolts. There are 5x120lb ft holding your wheel to the hub.. I forgot exactly but there's some huge amount of force holding it together.

If you think your wheels are held on with a bit of plastic (spigot rings) then hah! They are used for centralising the wheel. I wouldn't run without them but you don't NEED them.

[rich83]

So if the spigot is not there then the weight of the can is being held by the wheel bolts. They do take load mate.. .thats why they make hub-centric wheel spacers and adapters.

[xjay1337]

No, the wheel bolts do not hold the weight.

Come on Rich... think about it... they provide clamping force to hold the wheel mounting face to the face of the hub... each bolt can give many tonnes of clamping force..

The hubcentric spacers and what not are there to provide a) easier mounting of the wheel and b.) provide some reduction in vibration, due to wheels which are not centrally mounted, which can then cause wheel bolts to come loose.

[rich83]

Bolts are not meant to to bare the load of the car... thats all I am saying on the matter.

[xjay1337]

Rich, y u no read what I'm saying.

Once the wheel is clamped up, the hub in effect can be taken away and there would be no noticeable difference....

Once the wheel is bolted in place what keeps the wheel in place is the clamping force provided by the bolts holding the wheel mounting face to the hub...

You need them if you don't want a wobble.

I would never run a wheel without a spigot or a spacer that doesn't have the hub extension.

A spigot ring on an oversized centre bore will ensure that your wheel is correctly centred. This in turn will ensure that any forces that are exerted on that corner is evenly spread between the five wheel bolts.
No spigot rings on an oversized centre bore could mean your wheel is not correctly centred. This in turn could mean that any forces that are exerted on that corner may not be evenly spread between the five wheel bolts causing vibration and eventual failure of the wheel bolts.
I have used plastic spigot rings on numerous vehicles with numerous different style wheels on road and track with no adverse effects.

Yay an answer that pleases everyone! I hope. Haha. Thank you, I have purchased plastic ones as they were £5 delivered. Hah.
