Sven7's side view actually matches to The Template underbody better than the photo. Don't lower it, just add wheel spats front and rear. I'm sorry, I still didn't fix that bad cropping behind the front wheel
I like my method better because we are looking at 2D side views, which show what happening on the car's centerline. Away from the centerline the air is moving in the direction of the fender top not the backlight.
The inset is to show that it looks like Sven7 moved the Template down, but also forward along the rear departure angle.
Anyway, somewhere in this ball-park. Mix and match as necessary.
How about sunken '59 Cadillac taillights around where the stock bumper ends? They would be further apart, so the turn signals would read better at a distance in the dark.
