Well, I just lost my little sunroof deflector tonight - seems it didn't want to hold on past 130mph..... I had this guy on my tail on my way home, so I put my foot into it - we ended up chasing/passing each other for about 20 miles on winding back roads. All of a sudden I hear my deflector start vibrating and then nothing. When I got home, the clips and the bolts were still there, but no deflector...oh well, it was a good run.

 

Terminal Velocity of the deflector? I'd say pretty good, since our cars have a .32 drag coefficient

 

Mine gives me a warning...at about 90 mph the sunroof starts to whistle...

 

My old wind deflector was had a bunch of micro cracks in it, during warm weather it was just fine but when cold weather came along it would flap violently after 70- 75mph...I got a used one with no cracks in it and it stopped the flapping....

 

WTF are you doing???? 130??

 

i've always wanted to post this and never found a suitable spot: i dont theres anything to ruin here:
at least in the case of my sunroof, if i go past shut, to where the sunroof starts to tilt up a little, i can get it (pretty easily) just right so that it makes no noise whatsoever and is essentially as quiet as no sunroof at all. it being closed normally creates a lot of noise.

 

Something is wrong with your car, mine stayed on at 145mph










maybe that's because it wasn't on public streets.
