Mounting the camera behind the area being tested will be unobtrusive. Mount it on the rail half way back pointing towards the front. tape the tufts on the leading edge of window and back along the top.

Edit: Oh sorry, you said rails influence testing.... Yes, they will. Do the test in the middle of the roof between the rails.
Grab a friend with a hand held video and they can drive along side and behind. Or you could shoot the video since you know what you are looking for.
