I had the same setup you have. I went to the 5" flip kit and put stock shackles back on. Then cut a full coil in front. Without a c-notch I occasionally bottom out on the rear. I'm going to either put the stock hangers back or reposition the ones I have and bring it back up about an inch in the back to eliminate it hitting. If you flip it with the shackles and hangers you have, I would say you would have to c-notch it. Hope that helps.
