Hood moving at highway speeds
 
Hello,

So I was driving on the highways and I noticed that the hood starts to shake where the fenders meet it. Stopped at a gas station to check. The hood was fully latched and all the hood gaps look normal. Has anyone ever seen this happen before?

I can see my hood push/bend down when I pass through the air/blow dry at the touchless car wash.

The hood is made of aluminium, so I assume it will flex a lot easier as opposed to a steel hood on most cars.

This is pretty common. For me crosswinds really make it flex. It hasn't come off yet though, so you're probably fine.

Normal.

Can be adjusted with the latch and bump stops if it really bothers you.

It's normal. Like others said it's due to light weight aluminum and the bump stops.

I have only noticed this on shitty gravel roads. You should be able to adjust those rubber bumpers to minimize it.

It was just not adjusted well at the factory.

Take the rubber stoppers on the front corners and rotate them down a quarter to half turn. Should fix it. If it throws your flushness off to your fenders, then put the stoppers back where they were and instead crack the latch bolts loose a hair and barely tap the latch down a mm or 2.

If these do not fix it then it is an inherent problem with the construction and cannot be fixed easily. It is a minor annoyance at worst.

This is only a big problem with superchargers , when it rubs onto the top pulley and creates a very use full air vent through the aluminium.

Wow. After all the research I've done on this car and owning one for the last 4 months, I never realised the bonnet was ally. Very impressed!

Maybe that explains why my buddy thought the bonnet was gas assisted when he lifted it the other day. He's an ex race car builder so I am looking forward to telling him his observation was well founded. I'm sure he will also be impressed.

Well did you know about this:

http://www.tune86.com/sites/default/.../hoodprop1.jpg

The prop for the hood (or bonnet for you subjects of the Queen) comes completely out so that you can mount it in another hole higher up the engine bay to prop the hood almost straight up. Doing that turns the hood prop at a weird angle, but never fear: They put another rectangular hole at an angle in the hood itself, so that it still fits.
