Can I use wheel spacers in conjunction with wheel adapters?
Any advice is appreciated.

And yes, they are Porsche rims.
Different opinions here, anyone ever put spacers on top of adapters?

How can the hub take the weight? If the the wheels Arnt directly bolted to the hub?
The wheel tightly presses onto a circular lip on the hub (front) or brake disc/drum (rear), which transfers the forces and takes the weight.

Yeh. I get that. But in this case the wheel is directly bolted to the hub. Its bolted to an adapter which won't have your circular lip.
If the adapter displaces the wheel so far out that its unable to sit on the circular lip, then the wheel won't be mounted properly/securely by the wheel bolts alone. It MUST sit on the hub. Wide adapters are "hubcentric" in that they have the lip on them, and a corresponding inset which sits on the hub itself. This will explain why the proper adapters are £120 while plain old spacers are £20. There's a bit of engineering there.
So back to the original question. These things need to occur:
- The wheel bolts, or whatever bolts go into the hub/hub spacer/hub adapter etc, must secure with at least 4 full threads or ideally as many as possible without protruding beyond ie into the mechanism of the drum brake.
- Same applies to any extra bolts used with the adapters
- The wheel MUST sit on the hub ring of some kind
- If an adapter is hubcentric, it too must sit on the hub ring securely, ie make sure you use the right one for VW fitment (58.1mm I think?)
The wheel bearings will be under more stress but personally I don't think this is significant.
The main problem will be, whichever wheels you're fitting which need these adapters, will be oversize and them, or their tyres, will hit the wheelarch/strut/inner bodywork etc

The chap has said he is going to get some for twenty so you can assume they are halfords\universal ones. At that they may not be vw fitment. So they will not fit on the circular lip… So if it isn't on it, it will not be taking the strain. So what will be taking the strain if it is not Sat on the circular Lip?
You're right, in that IF the wheels and adapters aren't sitting on the hub lip then the wheel bolts would take the strain, which would be larger & different (it would take the weight of the car, as well as the clamping force, and as the wheels go round so would the vector of the force applied).
When people have tried this, the wheel bolts inevitibly work loose, no matter how tight they are done up, and the wheels fall off.
Hence why you MUST use hubcentric adapters, unless they are so thin that some (most) of the hub remains available to rest on. I think you're right in that 10mm adapters aren't going to be hubcentic, because there's about 10mm of lip protruding anyway, so it would not be possible to make the adapter like this.

hubcenteic spacers have the lip on them which the centre of the wheel sits on so what if you put the spacer beetween the hub and the adaptor so the wheel still sits on the circular lip ? the reason i ask is because im having similair problems :dontknow:
The hubcentric spacer won't be sat on the lip of the hub in that case, and you'll have similar issues.

Just want to clarify:
Hub - spacer - hubcentric adapter
in the above order is what I'm talking about, therefore I don't believe I'll need a hubcentric spacer.
In short, I'll need longer bolts from the adapter to the hub (10mm longer, as the spacers will be 10mm thick), and of course the spacers themselves.
Yay? Nay?
