There always is and expect more than one. I have never been a fan of restrictor plate racing, but if they really want to stop the bump drafting, all they have to do is remove the reinforcement front the front bumper. All the cut down spoilers, reduced fuel tanks, and whickerbills in the world will not stop it.
I will have to defer to Jr's expertise on plate racing. He said......
"It's a necessary evil is what it is. You can't restrictor plate race without doing it. You have to do it or we'd be racing single file and nobody will come to watch that.''

Stewart said he was hit so hard by Ryan Newman that his head bounced off the headrest.
"It should have knocked a filling loose,'' he said. "I've never hit the headrest so hard when I didn't back it into the wall."
