Weird grinding/scraping noise from rear wheels after new wheel install

[asdffdsa525]

Hello everyone, hope y'all are doing well. I got a new set of wheels & tires installed on my 2018 Mustang GT PP1. I noticed after putting them on that there is a weird noise from the rear wheels upon braking, like a scraping/griding noise. I let a shop install them and put them on. The rear size of the rims is 20x11 with 305/35/20 tires , American Racing TTF rims. I did not have that noise with the OEM wheels when braking, the sound only appeared after the wheels were put on. I linked a video that shows the sound:

Any suggestions/help would be much appreciated!

Take it straight back, try to avoid heavy braking
