Set of Four original 14x7x108 bc Minilites, Probably off a Trans Am car. In my possession since the 1980's. These have not been tested during my ownership so I can say nothing about that. I believe them to be aluminum alloy. There are inserts at the bolt holes converting the sleeve mount to conical.

Here are some wheel info from thread at (246) Common Alfa Romeo Wheel Weights | Alfa Romeo Forums (alfabb.com)
