Thanks for that. I wasn't looking forward to the work necessary to modify the whole front. I'll stick with grill block for now, and move on to wheel disks, air dam, etc.

It's a little high in that picture (I think there's a fried relay that doesn't bring it back to 'park' when you turn it off) but in general it does seem to be out in the airflow a bit. I did adjust where the arm sits on the spline so that it
should park as low as possible on the glass. I was considering adding a lip or something to the back of the hood to move the airflow up over the wiper. Do you think that would help? Or should I just take the whole darn thing off, and keep a 14mm ratchet in the car to put it back on in inclement weather?
