I think they are called "turbines", at least thats what I have heard them called. I think they are very cool in a retro way, honestly, if I could find a way to polish them and make them shiny I would probably keep them on my rig. Unfortunately as far as I know, magnesium will always look dull like that. Mine aren't perfect, a few dings and dents here and there, but if I am every ready to get rid of them I will let you know.
