After adding the roof rack and cargo basket to the roof, the wind noises were very present while driving. When the LED light bar was added, the noises was significantly higher than my liking.
Along with the sound deadening material, I also purchased a wheel roller to properly install all materials.
Installation was pretty simple and after using some spray foam to fill the gaps in the body parts, the noise in my Prius has dramatically lowered. Next up is the doors and floor in the Prius!
