1) where the attached flow separates from the body is, by definition, the separation line. The back of a truck box, or trailer van in this case.

Neither would have a place with respect to drag reduction of a road vehicle.

Here's an example:

A wickerbill on the diffuser affects the wake (allegedly).

I don't consider anything that has to do with dedicated race cars germane to road vehicle aerodynamics.
Everything he's done has only reduced the efficiency of the car.

Unless you count efficiency as 'Porsches passed'.

Front wheel covers
Small self drill screws on top half and light spring on rear attached to rocker panel. I can send some good photos if you want. Used the abs plastic from speedway, comes in a roll, very durable... At first I just filled in the wheel gap, and after a year I made another half moon to fill it in. I knew it would rub on turns, but I realized it never does on anything but parking lots. I though it might wear tire, but nothing ever did on sidewall. The wheels are 3.5 wide from a company called vms in FLA they weigh 11 lbs. The plastic started to wear through on one side after two years, and I just made another one. It seemed impossible at first, but I was really happy with it. The cops look at me but leave me alone mostly....haha
