    I don't know if this belongs here but....

    My 2012 has in my opinion a pretty severe hood shake/flapping at speeds above 60 mph. At the trailing edge by the windshield.

    I'm going to a track in March where speeds may be approaching 130+.

    Other than a Tiger hood, is there a way to calm this down ??

    I've been following the thread on S550 doing the same, https://trackmustangsonline.com/index.php?topic=10962.0 .I might give that a try.

    Thoughts ???

    Have you looked into hood pins?

    Hood shake at 60mph is not normal. Hood shake at 130mph is a characteristic of that year mustang. I would check the hood and make sure everything is how it should be.

    I had that issue appear one track day with my Tiger hood and it turned out to be a loose undercarriage plastic part just aft of the air splitter. Ensure you do not have some other part that has come loose that could be creating the unusual air flow.

    On the high speed shake,if all the bolts/hardware is good... I removed the molding under the hood at the base near the windshield,which helped my hood shake at speeds. It made for better airflow

    Just to be clear. It may only be moving an 1/8 inch or a hair more. It seems like the hood is bowing at the middle.

    I was thinking of putting body shims and a little longer bolts on the rear mount/hinge.

    This sort of hood shake is almost always due to an issue with the splash tray on the bottom of the car. If that is loose/missing you will get hood shake.
    If the under tray is fine try adjusting the rubber hood stops.

    Ditto on that - I've been north of 100 and not have any issues ...

    This is true and hood shaking at or just above 60 MPH may indicate other issues with air flow. I do remember rear hood shake issues reported back in 2012/13 but it was at speeds of 130-145 while running Daytona track days.

    Venting under hood air solved the problem, i.e. Tiger Racing hoods and to some degree, removing the underhood weather strip at the base of the windshield helped to some degrees.

    But shaking at 60? Something is wrong. Check your hood latch as well.

    Please let us know what you find.

    How did you get the shaker hood option, I didn't see that when I ordered mine

    Maybe I'm being too vague. I see the hood shaking at higher speeds. My wife has a hard time seeing it move, that's how little it moves.

    I said 1/8 inch at the trailing edge but it could be less.

    I had the same problem and it was distracting me at the track.
    I picked up a takeoff hood and added hood pins to the outer hood bumper holes.
    Made a thread in setup so I didn't have to cut or weld on the chassis.
    No more flex or shaking.I had the hood painted to look like a 69 Boss.
    Looks a lot better than the original decal too.
