Rim Stretching - the new tyre stretching!
Discussion
Everyone caned the VW lot for the tyres (rightfully), but this seems almost as bad:

Cut the alloys, weld in a new bit, then stick back on the car!

I can't for the life of me think why you'd want to do this - why not just buy split rims, and u can have any width / offset you need? Mind you, logic seemed to go out of fasion at VW events about 20 years ago, no doubt they'll be stretching steering wheels next =)
Yeah, these VW boys are absolutely insane - Especially the ones that hang around in the Holden forum.... 
I can't see the problem to be honest if done right.. (Though the title is worrying 
)
I seem to recall 1" of weld (done well that is) can support 1 ton - So surely one of these done properly would make very little difference to the integrity of the wheel?

Welding changes the grain structure of the material, this can cause internal stresses if not properly heat treated. Welding cast alloy properly is very difficult, you tend to get gas pores and possible cracking.)I seem to recall 1" of weld (done well that is) can support 1 ton - So surely one of these done properly would make very little difference to the integrity of the wheel?

So if you consider the sort of impact that hitting a pothole at 70mph would cause, on top of the forces your wheels normally cope with would you really want to risk the rim collapsing rather than just buying the right wheels in the first place?
The thought of driving a car with, effectively, cut and shut wheels would make me feel somewhat uneasy. Even if the finest welder in all of Christendom had modified them I still wouldn't feel completely happy. Aside from the weld itself, the increase in stresses and bending moment in the area where the rim section meets the wheel centre would put me off a little - plus the wider tyres would offer more grip, which would increase the loadings still further.
Still, each to their own.

Does strike me as rather pikey, why not buy whatever sized wheels you want in the 1st place? The Monaros are not yet the preserve of the council estate chav so a new set of wheels shouldn't be out of reach of the owners? Compomotive or Image will make you whatever you want for not a great deal of money. I'm sure rimstock would even do one off's, I know my wheels were made to order from them and they were cheap as chips, no doubt a new set of tyres will cost more than the rims did.
