The picture I used was the failure of a fake FUCH, not a real one. I've never seen a real one fail like that. As far as driving a 356, I drove mine all day Saturday.
First, it's FUCHS. The "S" is part of the name, not a way to make it plural. (It's German for "Fox", hence the fox-head logo. You wouldn't say a single fox was a fok, would you?)
Second, I've seen the real ones fail like that. One of them happened to a friend of mine, though the wheel in question had been (professionally) converted to a three-piece wheel. Cracked right between the lug holes, came apart, and damaged the car. He was thankful that it happened on the way
to a DE and not
at the DE.
I know of several more instances where real ones have failed in similar fashions, even without having been turned into three-piece wheels.
They're old, and it is very difficult to tell how hard they were used before you got them. You can Zyglow them for cracks, you can X-ray them, you can just decide the odds against it are really steep, or you can buy brand-new wheels.
For my car, at least so far, I'm choosing to ignore the problem and use my old wheels.
