That is weird.. I remember reading it earlier. I went back in my history, clicked on it, and it said it doesn't exist.
Are you sure you didn't delete it yourself? I know I didn't!
.... for your question
The only way you can over ride the spoiler at 57mph + is to pull the fuse. The switch inside will not allow it to lower once it has been deployed automatically due to speed.
Pulling the fuse will limit the down force on the rear of the car and it will loose some stability. Probably not enough for the average driver to notice. Not like the car is going to take off into mid air

If it did, I would save money on airline tickets :lol:
