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.
I meant the rails going across the roof. They're square section, not aerodynamic like the stock type
