I did notice when I experimented with an aluminum rocker panel molding on my car, that by doing so, it seemed to "section" the car and make the body look less, "bulky" or thick. But on the other hand, it seemed to raise its "chopped" top. So I have to agree, it does tend to make the car look taller.
