some info. i found...
"Ha this old gem. Il start by saying one thing, Wobble bolts are absolutely fine so long as you have centre location!
Also known as ‘PCD adjusting bolts’ or ‘Shift bolts’ they are very simple in concept. You have an insert that sits in the wheel seat with an oversized hole in it. A bolt then goes though the hole and because it is slightly oversize the bolt is free to move side to side slightly and compensate for a slight difference in PCD. It effectively does away with the seat and turns your wheels into wheels that use sleeve nuts!
Generally they come in bolt or nut form and for use with tapered and radius seats (although the latter is rare). Obviously you can’t use them with wheels that require sleeve nuts but that’s no problem as drilling the holes out in the wheels as I mentioned previously works on exactly the same principle!
2 downsides
Number one is that generally they are only good for a difference of up to 2mm in PCD, ie. Fitting 4x98s on your 4x100 is fine but 4x108s on your 4x114.3 isn’t.
And as I mentioned before you need centre location…Why do you need centre location I hear you say?
Well its very very simple, if your holes are oversized then the bolts are incapable of centring the wheel on the hub anymore so you need the location to come from the spigot! For this reason you can’t use wobble bolts on cars which don’t have a centre spigot."
