The front fenders are another part of the car where I got stucked in my aerodynamic reflections. The Saab 96 have a narrow body with an even narrower track width. The front wheels are located deep into the fenders.
On a car with wheels flush to the fenders, putting on smooth hubcaps is probably all that needs to be done. (and can be done). With the weels deep into the fenders I guess a fenderskirt is the best solution, but since the front wheels move a lot, the skirts must be hinged. The Saab 96 fenders are also fully open below, but that´s an comparably easy thing to fix.
I have tried to learn more about the best way to treat the air between the car and the road. An airdam seems to be the standard solution but I don´t think this is the best approach for the Saab 96. From what I have understood, an airdam is actually a quick-n-dirty-fix for an ugly looking belly! The Saab 96 is almost as smooth as a baby butt so I guess there´s no reason to avoid air from getting under the car.
My amateur assessment is that it´s better to deflect air captured by the lower parts of the front to the sides than compressing it under the chin of the car. This is why I thought of a splitter instead of making a softly rounded chin. If I make the chin sharp without a splitter I guess this will create turbulence under the belly.
How would it be to have a thin and sharp horisontal splitter in exact level with a flat belly? How far needs a splitter to protrude to avoid too much leakage over it´s edge? -I´m perfectly happy with the babybutt belly but the car would look realy silly if it has to wear a bib too...
