At track speeds over 60 or 70 MPH these aerodynamic aids are more than cosmetic if adjusted properly.

Now that I have had it on the track with a zero angle of attack and understand how the car feels, I plan on adjusting it by one or two degrees at my next track event in May. Small increments. Like you said, I don't want to overpower the rear end since I don't have a wing.
