Hi Mate,
Sorry for the confussion, I'll explain the reason for spigot ring.
Exactly as PPTom has explained these are used when the centre hole for aftermarket wheels is larger that the spigot of the wheel.
This is totally normal and spigot rings are commonly used. If fact I have them on my car for the Superlegerras.
You can fit the wheels without them as the will fit ok.
But you should not drive the car without them as the is a risk that wheels would not be central. Having said that I drove without them for a bit, but I got a lot of strong advise that this maybe dangerous therefore it is not recommend.
They are cheap anyway (and I'll send you another set) so no excuses
To prove the wheels fit ok here they are on my car, note I've already got the rings fitted cos I've got them for my leggies.
I'm a bit confussed cos the ones I sent should be correct, so just double check? Here's the description from ebay where I bought them?
Spigot Rings OD72.6mm-ID60.1mm Renault
Don't worry mate I'll make sure this is sorted out.
