I can't find archives of the streams. They did a live stream of the Mod Tour race at Charlotte and it was really bad (low quality, one camera angle, choppy) - hopefully they got things together at Bakersfield.
ARCA gave up on video streaming a long time ago. Of course, they were overpaying for that, by a lot. Think someone told me they were spending more than $10,000 per race. That's way too much for one camera on a rooftop. I think ARCA's going to sign with NBC to air whatever Fox Sports 1 doesn't air. Last I heard, ARCA wanted live coverage of the dirt track races, some short track races, and they were trying to get CRA coverage thrown in. Also heard that NBC broadcast coverage of a couple ARCA races was possible.
