I'm speculating Fox and fox sports 1 will show at least some of it, since they are picking up a lot of speed channels offering. Some of it may also be on FS 2. Although FS1 will air a lot of races after the fact....
Worst case you might be able to pick up some of it on ustream bootleg feeds, or some of the manufacturer telemetry in car feeds from Corvette/Audi.
Also Eurosport is supposedly in a deal w/Discovery networks for some US distribution, so it might show up there in some segments.
I think it would be safer for your to attend the race in person
