Hi,

While Time Trialing the car, you run your laps with the windows down. I

noticed the other day all the dust I have in the back of the car. I was wondering

if the dust would decrese if the roof hatch was open.

The question is, will the car be faster with the roof hatch open or close with all windows

open? I am sure that the Germans have done tests like this but us Americans

may not be able to get this information.

Logic would tell us that the car would be faster with the roof hatch close but

maybe the interior car pressure would improve with the roof hatch open. I will run

some racing laps in the future and will experiment with the roof hatch.
