Im dropped on GC coilovers with 215/40/17 and my rears are rubbing on the fender lip. I know you can roll your fenders but has anyone tried shaving them with a dremel? I am thinking about doing this as opposed to rolling them because I want to prevent my paint from cracking. You think this will work?

they will rust if you don't paint or clear coat them. You can either 1) get it rolled professionally or 2) put more negative camber in the rear or 3) raise it up.
