how good
I've never seen numbers reported for this car.For lower drag,a full streamliner body is used,enclosing the wheels.Even with the larger frontal area,the overall drag is reduced.
So-Cal Speed Shop did such a thing with their famous belly-tank lakester.
GM did it with a March Indycar chassis,creating the OLDS AEROTECH of 1987.
The drag can be cut in half this way.
