Is any clearance enough? I bought 4 tires and wheels at a great price from friend. But then discovered that they don’t quite fit. I put a set of one inch wheel spacers and they fit fine. I’m not comfortable running spacers for all the known reasons. I recently rebuilt the entire front end and decided to look at clearance issue again. Anyone remember the technical term “rch “? Well that is what I have. With everything in place I need 1/16 to clear the knuckle arm and outer rim. As I see it all I need to do is grind the outer top edge of the arm 1/16 and all is clear. In my mind since the arm and the outer rim position does not change it should not matter if I have 1/16 or an inch. Have I missed something obvious? Thanks for any input
