You do not have to do any of this to fit 275/60/15. I run these tires with no modifications on my other Barracuda and my Duster that has the same wheel well.
I guess I butchered up my car?
Mini tub, and spring relocation. To me that's butchery. I just finished reversing an absolute mess done that way with aluminum tubs and pop rivets, so I kinda feel a bit strongly about it. Did not mean to offend.
