Could they put more wing on the car if they wanted to? Dont the Pro Stock rules prevent that? they showed pices on tv and on internet where "chunks" small aggregate really were lifting on the track after the fuel cars run, they cut some tires because of it,also claimed by Dim Light that water was coming up through track because of the lower temps, Salt Lake City's Rocky Mountain used to do that, seen several wrecks and called races because of that. Pro Stock is allways on the edge since they lack downforce, a slick track just makes that worse.
