I suppose the only risk if you have an accident with them fitted and the insurance company wants to wiggle out of paying up....Quote:

A crappy spacer is made of porous cast aluminium or plain non-alloyed aluminum so it crushes under side loadings (cornering) which reduces the tension on the wheel nuts/bolts allowing them to loosen. Worst are the non-hubcentric porous ones which crush more quickly
Since spacers are not easily inspected and could potentially be made from cutouts from sheet bought at Bunnings, only ones supplied by the manufacturer as OE fitment are legal as they are certified along with the rest of the car.
Really can be found spacers made of cast aluminium...? Yes, I agree, they are crazy!
Personally I mounted Sparco spacers (do you know Sparco? It's an Italian brand making special parts) machined from solid aluminium and mantaining the original wheel centering, with longer quality screws: no vibrations or other issues, except the different behaviour and response of steering wheel, due to the changed geometry...
