for y'all with duckbills on your EH hatches ... do they actually provide some downforce? it seems that with their shape that they would. i want more stability at higher speeds, but i don't want an alum wing on top.

 

thats what the spoon wing was designed for, a stable rear end during high speeds.

 

yes, but do you notice it? from say 80-110mph?

 

I cant tell any difference on handling, I got mine a couple years back cuz I loved the way it looked on the car. All I can tell you that its durable.
