There was a total of one winter wheel that had a ring installed but is was so badly damaged. All the others had nothing. These were like 10 bucks or less on Amazon. It just took some effort figuring our what size to order.
I’d guess all Subaru going to be the same hub size 56.15. It is finding what is needed for for cheaper brand models.
This removed highway vibrations. Although I do not know how well they tried aligning them with lug centric method. I did tell someone at the desk, but doubt it made its way back. I have seen how the air tools are used, improper torque sequence, over tightening lug nuts etc.
Also removed catalytic converter heatshield to replace missing mounting tabs from the part.
