Your theory about angles and such is correct to the extent that the lower the angle the less downforce created but higher drag reduction and vice versa (to a limit of about 14 degrees.) Eco-modders will build diffusers for drag reduction and try to keep them close to 0 degrees, not generating downforce but reducing the drag drastically. I've thought about doing it on my kid-hauler

I spent a LOT of time reading through your wind testing thread, that on top of the exhaust made me decide to change it up. I can't believe the milage/stability difference in just changing the angles/fins.
