I
I had some issues with noise on the drivers side front corner of the targa panel. Also had some leakage if high pressure came from the side. Made some adjustments and put a new seal in and the issues are gone. It took a bit to get it perfectly adjusted but its been fine since.
That's the hard top retrofit bracket. It's not needed if you plan to keep the soft top. I put in a hard top from rallytop and those come off along with the soft top brackets.
