Bonnet shaking at high speed
Yesterday on my first trip out on the autobahn. I was doing about 120mph when the bonnet started to shake. I'm guessing the scoop provides a certain amount of lift at this speed. Has anyone else experienced this? Any cure needed?

Not the scoop! The air passing over the front of the bonnet turns and increases speed as it passes onto the bonnet. This causes a pressure drop and temperature drop according to classic Benoulli's theorem. The low pressure pulls the front edges of our lightweight alloy bonnets up. At 120mph the outer front edge sits about 1" up from usual. Quite worrying.
I also will go down the aerocatch route but my Hawk is a bit too new to be devalued like that yet.

Does it have any slack if you push down on it?
A possible simple fix would be to adjust the bonnet adjusters. The rubber thingies behind the lights are a screw fit that you can raise and lower.
