Wheel fitment

[droptop]

Folks, as usual I am looking for advice. I have a brand new set of alloy wheels with tyres which I spent a lot of money on a few years ago (They were a special order) and the PCD is 100mm. Can I bolt them on to my Spider?
I fitted a set of Opel Rekord alloys to my Fiat Strada back in the day without realising the PCD difference and the only mod. I carried out was to grind the centres of the wheels in order to fit the front Fiat hubs using a hand-held die grinder. None of your fancy stuff for me!.
Anyway, I had no problems and would hope to repeat my success with my Spider but at this stage, I am concerned about getting things right. I am getting more conservitave in my thinking in my late middle years.
Any comments and/or advice is welcomed, especially the positive kind.
My thanks as always

you can buy 'wobble bolts' which have loose heads and will align with the 98mm hubs, personally I think they are a dubious bodge but folks use them and they appear to work, anything with grinders is out!! you want a perfect and secure fit. Have you checked if the offset will be suitable as well and what about the hub centre bore as well?

I have heard of wobble bolts all right. Offset is fine and centres are big and a specialist shop in Fintona supplies adaptor rings with the correct inner and outer diameter. For the price of the bolts, I will give it a go as I need new bolts anyway.
I have no intention of attacking them with a grinder and I may try a rolling road to apply a decent realistic load before going on the highway.

I've always steered well clear of wobble bolts. 

Just my opinion... things that hold my wheels to the car should be rigid/solid items.

Someone once said "Try everything in life once, except incest and Morris dancing" and although I have added a few other things to the list, I will try the wobble bolts. Think of it as research on behalf of everyone who wants to fit wheels of the wrong PCD to their cars.
I will post the results of having them on for the season if they stay there and if they don't, my family will post my obituary and you can draw your own conclusions!

With wobble bolts,it's the tapered washers that move,only by 1mm,nothing to do with the bolt.The name is very misleading. They're a sound peice of engineering. If you see them,you'll see what i mean. One thing though,with wobble bolts,you MUST use spigot rings to centre your wheels as the bolts will not.

I have experienced spigot rings on my old cavalier sri and if you dont have them on any after-market alloy that depends on bolts rather than nuts, then changing a wheel becomes a chore so i am getting them for both reasons. If the correct size isn't available, I will get them turned on a lathe. There is only so much hardship I can put up with and having the wheels off-centre is a step too far. Thanks for the advice
