Especially with the speeds and component stresses involved in racing, how do they get away with this?

The torquing, I'm guessing, is predetermined in the air gun. As for why circular vs star, well that I can't tell you. Maybe it doesn't matter for the race cars (like NASCAR) as the hubs will probably still line up because of the degree of torque from the airgun, thus not allowing it to get stuck at an angle? Maybe their hubs are designed in a special way so that circular pattern won't negatively effect tightening the wheel in a symmetrical pattern?
Good question. That's why center locking wheels are the best for racing applications. Just 4 locks total and you're good
