Getting back to the Fiberide wheels; I decided recently to model this rim based on measurements taken from my sample. This was a fun project for me, allowing me to explore some more advanced features of Solidworks (I used the 2006 edition). I would like to someday work some freelance solid modeling, perhaps creating a freelance design firm in the distant future. Hey, I can dream, right?
Here is a screenshot of my model:


Fiberides unfortunately don't seem to hold up well if you experience a tire blowout; perhaps some a serious Turbo Dodge enthusiast will one day want some machined alloy "Fiberide" wheels and I can make use of my CAD model...
