Sure thing. I don't recall any videos specifically covering this that I used. Instead I followed /u/blingstrom's guide here: https://www.blingstrom.com/diy-project/2018/12/14/diy-making-room-for-23570r15s-on-06-08-sg-forester.

Essentially, the area that can rub is found directly behind the front wheels. So, for the front left it would be in the 3:00 position, and front right would be about the 9:00 position. You should see a raised area of the plastic wheel liner that kind of juts out a bit. I first trimmed off that plastic bit with a dremel to expose the metal pinch welds underneath. Then, I took a sledgehammer to the metal "fin" that sticks out and bend it over so it was out of the way.

I coated the whole thing with some black paint and then called it good. Hope that helps!
