did some more mods will update shortly. However biggest thing i noticed was with my wiper blades. i first did some tuft testing to see just how much air actually does flow over them. had the old multi brace web type. lots of people here saying there is like a low pressure around the bonnet to windscreen transition and not much airflow over the wipers. i believe it is car specific. after the tufts got ripped off on my daily drive to work at about 70 mph i decided to changed them to the type in the pic and cut that extra darker grey peace on the top off. i then bent my wiper arm handles to better 'tuck' in behind the edge of the bonnet. the wind noise now have DRAMATICALLY reduced at slightly higher speeds. i will do before and after pics soon.
