Wheel spacers and spigots
Hello all
My car is suffering from vibration at certain speed, I have two 3mm spacers fitted on all four
Wheels and no spigots, I have noticed the spacers do not always sit together and may not
Run exactly true. Also because of the spacers is running a spigot a waste of time I presume
The spigot centralises the wheel on the hub and by running the spacers the spigots will
Not make any difference.
Any tips on getting everything true?
Thanks in advance.

If you are running two 3mm spacers I recommend a 5mm or greater concentric spacer . These are available on ebay
181216333377
As you have found you should not do without them above a few mm as you then have no Spigot effectiveness from the original hub. This can lead to
failures if you are not careful. On one of may cars I used a 10mm one and machined it down as it was a non standard application and I got them s/h
from ebay.
Best of luck

I was led to believe the spigot is only to assist when putting the wheel on and the taper of the
nut and wheel are what positions the wheel correctly. I don't have them on mine and do not suffer
any vibration issues.
You could pin the spacers together, but as they're thin and small diameter I wouldn't have thought it
would make a significant effect on balance. Have you checked for wheel balance and mis-shapen tyre ?
I have come across tyres that balance perfectly but only cause issues in use.

I don't wish to be critical of you but where safety is concerned straight talking is sometimes required. You are so wrong!

Although I'm not necessarily disagreeing with you, I would verify any information found on a website that actually sells them.

It can result in premature failure of anything that is un-sprung. It can even cause chassis damage if causes a particular resonant frequency (I am
told). If you don't have a problem with vibration then you do not need spigot bushes unless you make a mistake aligning the wheel. So best have
them in my book.

As I recall, spigot rings only started to appear on cars with bolt fixing hubs, and these were needed to hold the wheel in place while aligning the
holes so you could fit the bolts easily, they work like adaptors when the bore is larger in the centre of the wheel.
Cars fitted with wheel studs never had any need of spigot rings, because you just fit the wheel over the studs.
The tapered hole in the wheel if forced into allignment by the tapered bit of the wheel nut or bolt.
How can a plastic ring make any difference when the wheelnuts are tight ?
Can you run the car without the spacers to see if the problem still persists ?
If it does then the wheels need dynamic balancing, this will also make sure the tyres are true.
