I thought Volvo was 112 tbh.
114.3 is stamped on the wheels.

What's the hub diameter?

Oh, and how deep is the spigot on the hub?

One more thing, are these actually safe?

I don't see how one of the wheel bolts could go through to the hub because of the differing PCD's - the only way to fit them seems to be three bolts from the adapter to the hub and 5 studs on the adapter (like in the pic).

The guy who's making them for me says he's done loads of them before - just seems strange to me?

One can go all the way through, because you index the rest of the holes off that one, and if the pcd's are right they will all miss. Just like them adaptors you posted one goes right through.

just out of curiosity how much would a set of four cost? if your guy was willing to do more than one set ed?

Also a few people run the above adapters and ive never heard of any problems.

Cheers

So you end up with eccentric male and female spigots to re-align the wheel to the center of the hub? (Sorry, just trying to figure it out for my own 'education' - they will be made by someone who knows what he's doing!)

I'll find out later on today when I go over and speak to him, then let you know

I can get just about anything made from there so if more people need things doing then it would certainly be possible.

Feel like an idiot, but I can't see how these are meant to work? If there's a varying PCD, how does the wheel rotate correctly if a bolt hole is being shared?

Seems like everything I try ends up with the wheel rotating in a sinusoidal manner in the x-axis.

Look at the left hub adaptor.

The 3 counter sunk holes will be used to attach the adaptor to the hub with the 3 black bolts in the pic. Then the top left hand hole (4th hole) will use the longer silver bolt to attach it when when the wheel is fitted. It will go through the wheel and right through the adaptor and onto the hub. Then the remaining holes will be for the rest of the wheel bolts to go through.

nope they are aftermarket
maybe the hole can only be shared when the pcd is same size 4x108 - 5x108 etc

Me too, I can't see how it would work otherwise. Unless you're keen in your suspension being shaken to pieces by 4 unbalanced wheels.

Could probably drill the hubs and discs out to 4x114.3 and then build an adaptor for them which shares one of the new bolt holes. Could be a bit of work though as the hubs would need to be pulled from the knuckles and they tend to be hard as fuck!

You wouldn't be able to drill the hubs to the 5 stud pattern unless the original holes were plug welded and you need spacers anyway so the first idea might be best?
