Ok maybe a dumb question here but how are they making adjustments on the cars? I know they sometimes remove or install spacers in the springs when they change tires and adjusting air pressures is a big deal. But they used to crank on the cars at the back window. One of those adjustments was the track bar but I dont remember what the other was. Of course the drivers had, for a few seasons, an in car adjustable track bar toggle switch that they could fiddle with while racing. Nascar took that away a couple of years ago. Why don't they crank on the cars at the rear window any more? Are spring spacers and air pressures the only adjustments they make anymore? What did I miss here that they stopped making adjustments cranking on it at the rear window?
