Hood "tremor" at speed

[Alfa 2407]

I have the deflector and have seen these reports but haven't noticed a problem, did 95 mph once just too see, had minimal vibration (95 is not a typo)

It is my understanding that the problem is there is a gap between the hood skin and the bracing below it, the deflector diverts air and seems to create a vacuum in some instances (or something along those lines) causing a vibration, this could also change based on location as air pressure changes, from heat or altitude above sea level

Also to those saying drive slower than 75 or 80...I believe both Texas and Montana have speed limits of 80-85...which generally means 90 here in TX

I live in Texas, the speed limits here (north Texas DFW area) range between 60 and 75 for highway

I’ve had two bronco sports with deflectors and two without. One with and one without was a 1.5L and one with and one without was a 2.0L. They all vibrated, some closer to 70+ and some closer to 85+.

No offense, but either yours is special or your not observant is my non-scientific conclusion.

Lol 70yo and 110 cars later. I would certainly notice a hood vibrating at 80 mph. Like a lot of people on this forum complain about things I never had a problem with.

85-90 mph never a problem either

I am on the opposite end of that spectrum ? 19yo and first car I ever bought new, last one was a hand-me-down toyota highlander, but yes, I agree, in my case and sounds to be in yours too, very minor shaking, minor being it's better than the 1977 el camino that has been in my family for 45 years, it has really bad hood shake, and that sucker is steel ??

Mine is the 2023 Outerbanks, and with the deflector, I have no hood vibrations at all. I've had the BS up to 80 MPH, and again, no vibration.

I think there are a lot of factors at play here. The video from OP was taken from a very low perspective, which makes hood movement much more apparent. If your seating height puts your head up high toward the roof, hood movement may not be so noticeable. In addition, "tremor" can be a very subjective term. One person's tremor is another's earthquake.

Especially if it involves a large plate of pinto beans...

Wait...what? 4 Bronco Sports within 2 years?

S'up BS Fans?!?

So I added ditch light brackets from HRG and I already installed the air deflector.
What I learned from all you and recommendations from HRG- the hood can be adjusted in so many ways from the bumpers to hinges . I am still "playing" with all the variables to reduce any noticeable "tremors" . Once I find my "perfect" settings- I will post here .

BTW- 99mph on hwy40 NM - on way to ABQ is a great testing area.
My WeBOOST did not survive- got my first dent there. LOL

And a Bronco

It is not air being trapped. There is no bond between skin and under hood skin bracing

I don't understand what you are trying to explain. If the bracing isnt attached what is it supporting then ?
