73.1 to 72.6 spigot ring -disaster inevitable?

Post by McTrucky » Sun Dec 10, 2017 1:36 pm

I am thinking about some ac wheels, but they are 73.1 centres. I can see spigot rings availble to convert these to 72.6, but I am thinking the thickness of these rings must be 0.25 mm.

My thought is a ring this size is going to be so fragile that damage is inevitable swapping wheels about. To the point that these rings would need to be considered as consumables, and it is inevitable that I will damage one during fitting without knowing it, so potentially mounting the wheel wrongly and not knowing about it.


Should I forget about any wheels at 73.1. Any thoughts?

Cheers
Alan

Are these genuine AC Schnitzer wheels?
Not heard of that size centre bore on genuine wheels before..

I have older type 3 wheels and they are 82mm centre bore

Nice and light. :thumbs:

It would be a thin ring, but might be ok with a little grease on. What material are they made out of, moulded plastic?

Ah.. No they are a separate company to Schnitzer..

Perhaps you can email them for confirmation that they will fit your car without spigot ring of if they can supply something to bridge the small gap.. Seems strange to have 5x120 with 73.1mm centre bore

Need to wait until they are open on Monday to contact them, but I am sure the salesman will be saying, "Yes, no problem, comes with fitting kit, everything is wonderful".

But reading into what you guys are saying is that it should be fine, spot of grease to hold the ring inplace when assembling should prevent any issues.

They will be track day wheels, so on and off lots of times, so not really a fit and forget for a year arrangement.

I could consider bonding some shim steel to the alloy I guess.

For track wheels I'd want metal rings, I've seen the plastic ones melt.

Someone makes spigot rings that are a quarter of millimetre thick? Seriously? :shock:
