    ... out of curiosity, how often do you go over 210km/h, i mean it must be often such that it becomes this annoying...

    Two weeks and already taken it past 210km/h? That's an interesting way for running in an engine.....

    As for a solution to your problem, I've got no idea.

    Never been over 200km/h so I'm unsure if my car has same issue.

    Good luck in finding a fix.

    Either they have unlimited speeds like Germany, or he's going for speed records on a salt pan?

    Try hitting a Cyclo or Tut Tut before you reach 210klm hr ,that should fix the shaking bonnet..
    On a more serious note, try lowering front tyre pressure to 20lb and increase rear tyre pressure to 55lb, this will create a wedge shape ,and as per the laws of physics ,the wedge shape will lessen air pressure on bonnet and create more downdraft on rear. Very important physics maths equasion A/b=T+-0.355/6.
    Have Fun.

    easy to fix wind out (a little) the front bonnet rubber support things and go to clark rubber and get a thicker rubber liner and glue it to the original one that runs across the wiper cowling stops a lot of the vibration

    There is a lever just to the right of the dash. It looks similar to this.

    When you see some movement from the bonnet/hood. Pull the lever, that's what it's there for. It'll put a deadbolt in the bonnet catch mechanism which means it ain't going anywhere.

    Another interesting fact, if you say Gullible very slowly it sounds like Oranges.

    Have a nice day!

    P.S IGNORE THIS POST...what post?

    Unbolt it take it off! Then you don't have to worry, provides better airflow and becomes one mother of a bonnet scoop!
