It'll cost you 10g's for a loose lug nut, more than that and a crew chief suspension if your LF fender is 1/64" too low, but it's perfectly fine to run down into the corner and knock someone's rear bumper off to win a race? Maybe that's why the stands are empty and TV ratings suck. Horsebleep racing. I'm telling right now, I race a guy clean, pass him and he dumps me to win, he's getting his nose bloodied, no doubt about it. If Nascar allows it, they can go jump in a lake too.
