Spoke to their represantive for a bit and expressed my concerns for the wheels shattering if load is exceeded or if it is damaged but he said there is nothing to worry about with the process they use. No idea how accurate that is but that is what I was told. If the wheel is damaged it should not completely fail.
Additionally, they said they are capable of making large sizes for heavy cars but currently they are showing these off with the Porsche crowd. They also are planning on expanding into large transportation markets where these wheels would offer fuel efficiency savings on say trucks that need to traverse a long distance and where fuel economy is at a premium.
I picked up the wheel. Let's just say you can do it with one arm easily, impressive.
