[John Rogers]

Unless the rules changed from a couple years ago, the car is weighed with driver fully suited, remote cameras installed, X gallons of gas, full oil system or escentially ready to race.

In DW's book about the early days of NASCAR they used to use lead, fake radios and then switch them until one was dropped on an official, load the frame tubes with lead shot and pull a small cover after race start to dump the lead but they got caught when a driver was dumping the shot and had to go down pit road to miss an accident....... They started weighing the cars AFTER the race too, still do. Then Smokey caused them to start using templates with his "small sized" cars!
