You hit the nail on the head, Martin: the only reason I'm somewhat reluctant to predict that this will be a success is that it increases frontal area so significantly. It easily adds more than a square foot to the car.

It certainly breaks the "don't make your air dam lower than the lowest hanging underbody parts" rule of thumb that is sometimes mentioned.

Yet I often see OEM drag-reducing dams that extend below the lowest underbody level of production vehicles, which is why I decided to go big or go home.

A-B-A results to come tomorrow.
