Mazdaspeed 3 Front bonet vibrates fiercly once over 210km/h

Hi guys.... i just had my mazda 3 MPS gen 2 two weeks ago, i am facing minor problems and seeking tips, comments from you guys.&nbsp;<br><br>Everytime i go over 210km/h, my front hood vibrates fiercly, i wonder if this does happen to other MPS?&nbsp;<br><br>I am thinking of fixing bonet clips, any comments or suggestions which type i should go for.<br><br>Anyone knows what's the factory boost settings? If i want to boost up, what's the recommended pressure?<br><br>Thanks guys... Cheers!<br><br>Aznee<br><br>

... 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.

O geez, here we go. LOL

As long as he's doing this on a private road I dont see a problem with it.

I have an idea! Just remove it all together! Problem solved :woot:

Duct tape fixes everything.

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.LOL.
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.:cheesy:

Can you see the bonnet moving? or only hear it?

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

Thanks for all the positives feedback guys :motion:

I'd pin it down to be sure

I have some race tape... it's blue tho

blue will work fine on my pearl white

i am seriously thinking about that. Just need to be sure, before the hood flew off lol.....

No comment!

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! :2thumb:
