Interesting stuff, I did wonder if they might be forged.
Makes you wonder why the originals were magnesium, in my experience they are no different to the race wheels i.e. no added material - which might be why they crack rather easily..they do sound cool though!
I would imagine they could make identical copies with your old wheel as a datum point.
This is the issue - with the magnesium wheels in racing at the end of the season they bin them. If they damage them they bin them.
And racetracks don't tend to have potholes and cats eyes and speed bumps.
Magnesium wheels are just not a good idea for a road car.
If you're ordering a new Porsche GT4RS for example you can spec magnesium wheels for an extra £11,000 (that's not a typo!).
And if you kerb one, or damage one on a pothole? Buy another one.
Yup, we're planning to start with a "copy" of the original wheel and then see what the CAD says about weight and strength and go from there.
