Mysky open over 45mph. Fear?

I look up while im going sixty mph and mysky portal open and it is shivering like crazy. Should i be scared? Anyone notice or try to reinforce?

 

I just crack open the windows if I'm on the highway and solves the issue with the airflow.

 

Yea i had all the windows open. And the middle pillar was shaking hard.

 

Ive never had that issue, and I keep my front open ALOT. Now at 75mph its a tad louder, but yea that's an obvious thing

 

I wonder if mines loose

 

May be loose, the only time I ever saw a bad shake with mine was the first time I hit highway speeds with the windows closed. I have it on the highway all the time with the windows and top open and don't see anything that gives me concern.
