OK, so im cruising around in bimmer and out of boredom, i start thinking. i had my rear sun shade up(the back winshiled, dunno what they call it), and all my windows down and i noticed that i was going about 80 miles and when i looked at the my mirror, i noticed the sun shade was SHIVERING, due to the wind blowing on it. so i go scared it would rip

Is it possible for it to rip at high speeds if windows down? and due to the mechanism resisting the wind force acting on it, it may get damaged one day since they are weak ( yes im an Engineering major).

I don't think there would be enough excursion of the sunshade to stress the seams of the sunshade. How much space is there between the sunshade and window?

i dunno aprrox how much, but i think it would tear down, since it is not parralel to it, rather diagonal

well mr. engineer, if you find the tensile force of the materials used I think you have yourself a math problem.... :lol: :P

hahaha.but the thing is, there a more then a 100 engineers that engineered this beautiful car.so dunno if they thought of it or just forgot bout it. dont wanna suffer the consequence. thought id share it so no one else does suffer and spenddss $$$$ fixing

Cheers
