Pretty pedestrian 1960s 1970s cheats. BTW Smokey's shop was only a couple of miles from the track so driving there was no big deal. Most of the cheats talked about here would be caught in a second today. The big thing today is aero advantages, like back windows that flex down, spoilers offset to one side and getting air out from under the car. At about 15,000 square inches of surface area looked at straight down on a cup car, reducing the air pressure by 1/4 lb. under the car equates to 3,750 lbs of down force.
