If the cars had a solid-built 1-piece tilt front cap Talladega & Daytona would the cars stay on the ground?
if you have the back of the car lifting, I'm not sure I understand how the front lifting would cause the rear to settle back down- as opposed to just lifting the whole car even higher. I do like the idea of just replacing the whole front cap in case of an accident. Didn't they used to be able to do that in SCCA in the 80's? My opinion of the best way to get rid of restrictor plates? Smaller engines. The teams already have special engines for the plate tracks, so just make them smaller.
I actually have a design that utilizes two ports that are integral with the body panels, which mean there are NO MOVING PARTS. They are angled and contoured to only be effective if the car turns past 45 degrees. After 45 degrees air is automatically evacuated inside of the cabin of the car, and since it cannot be trapped because the windows are open, the car cannot lift. I would love to share the design with NASCAR, but I would probably want them to pay me for my ideas. I hate wasting a good design
