Since my Civic has a large radius, I figured that was giving me the best aero performance short of a full Kamm type thing.

So, I think the question of whether a partial Kamm will help or hurt depends on the initial design of the car. Civic..Not so much, 96 Tempo....prolly will help.

Do you mean this one?:
