I personally removed the XREAS as it's only a few bolts here and there, and would clean up the frame a little, as well as make adding sliders easier. I am running 285/70 with 17x9 Fuel Kicker 6 (+1 Offset) and no rubbing. I did the body mount chop in prep of the lift, but I'm no where close to rubbing. I also added SPC upper control arms when I did my lift.
First pic is with OME springs front and rear with the 5100s on the highest setting. It sat a solid 2-3" lower on the back, I highly suggest not setting the front shocks there for the obvious reasons. Also it was way too much preload on the springs and caused the front to bounce under 40 mph. There was a good thread on here just a few days back about only setting the fronts at the .85 lift setting.
Second is a pic with the ICON 2" springs on the rear with a 1" cornfed spacer. Still squatted but not as bad.
Here is a pic of the 5100s after i dropped it to the second setting.
Lastly is a pic of the stock springs next to the OME 895e next to the Icon 2" for height reference.
After adding a front bumper, it looks to be leveled out.
