Well I am going down quite a rabbit hole now. I recently ordered Julian Edgar's newly released book. Very down to earth and all practical solutions to testing and tuning production car aero on a tight budget without CFD or wind tunnels. For example he uses a throttle stop to measure changes that affect drag. Stop the throttle at 10 or 15% and measure top speed at roughly 50 or 60 mph. Make an aero change, then check top speed again. Not cheap, but 500 pages packed full of info and lots of pictures. Highly recommended if you are looking to reduce drag and lift on your car.
