i recall at least one thread on this some time back. haven't done the search to find it though. basically comes down to just disturbing the airflow as it comes off the back. Carbon Joe's spoiler is at about the best possible position as i understand it (which means take it with a grain of salt). the top of the rear window would have about the same effect i would suspect. i have that setup on my Passat as a matter of fact using a BMW 3-series trunk lip spoiler, but that is apples and oranges.

just about anything you do to disturbe the airflow some would be a plus. garbage in, garbage out. the shape of the bug just wasn't designed for optimized airflow. you can only make it better. it will never be great.
