OK. I so wanted to find out if the stock spoiler(?) on my car does anything at all. Right my plan was as follows:

1. tuft test it
2. pressure puck on the top, maybe bottom, but might be a tight squeeze and therefore possibly inaccurate.

I don't have a direct picture on hand right now, but these should help.



I have tufted the back window and given the distance from the spoiler to the glass I don't think it will be in attached flow.
