I mean does g-force and speed tracker help you setup your car ? We are in the 21st century now. Tech savvy people can figure things out. I can see a day where you rent a track, collect data from sensors located all over the suspension and frame. Then using AI to setup the car and monitor changes. All you need is a nerd.
