A long time ago I was driving for a guy who was telling me how gullible racers were. To prove his point, he got one of those rods with a huge turnbuckle on it and welded it into his late model. One end was attached to the roll cage behind the driver's head, the other end went out through the floor on the passenger side. That end of the rod wasn't attached to anything. Every time the car came into the pits, he would adjust the turnbuckle. Within two weeks, a dozen other cars had rods with turnbuckles welded into their cars.
