Im sure brake temps might be higher but not too many guys here are exercising their brakes enough for damaging heat levels to be considered. And im sure there would be a small gap to let some air into the rim. But i just think it would cut down on the rim turbulence in a big way if this could be done safely and effectively. It might even make the belly pans more effective.

Lakesters at Bonneville use them.Really, all the fast open wheel racers.
Danika Patrick has them on her Indycar ( carbon fiber,very nice!)
I have considered doing this on the trailer.They would have to be mounted on the axle,as they wouldn't make it past the hub if on the wheel itself.
I'll do the lower-hanging fruit first and then if time remains,I'll cobble something together.
Ford's inner fender,along with the urethane rubber wheel spat on the Probe-IV was good for a 9 % drag reduction.It's the only 'science' I have for such a mod,but it clearly demonstrates a drag reduction when the wheel is 'cleaned.' And this is a full bellypan car with only 3-inches ground clearance!
If anyone is seeking really low drag,then this sort of mod is certainly 'on the table.'
