You probably would reduce the stiffness of the body which was not all that great to begin with. If you are adding HP I would not even think about it.
Can't imagine why you would want to, unless it's to remove weight, but it's such a small amount of weight and car needs it for structure. You can shave weight in a lot of other areas (fiberglass panels, alum wheels, fuel cell, etc.)
