HydroJim -
I agree that wheel covers would help the aero. The extra metal (convector) in place of the tire (insulator) would also help in cooling the disk brakes, yes?!?!?!?
It's definitely cool. As Frank says, it seems like there are all these multiple points of failure. The good side is that it appears (to me) that it would fail gracefully, i.e. the bolt connections would degrade to the point where they as a problem would be obvious. The (TBD) bad side is how durable it is. Would it last say 60K miles? Or would the replacement interval be split up where the metal portions would last maybe 200K miles with the rubber parts being replaced maybe every 20K miles?!?!?!?
Me not know,
