Great photos,and love the look of your work! I think your project fell victim to the diminishing-return/negative-return,as the depth of the airdam added a significant increase to the cars frontal area,increasing drag by a corresponding factor.Should you have had Hucho's book,you would have found that if the airdam projects below the elevation of the lowest suspension member,drag will begin to grow as a percentage of the percentage increase in frontal area.Bummer! The book is invaluable to any one considering aero modifications and can soon pay for itself in time and material saved.
