3.75 backspacing

Bad backspacing
if you just have to have 8 inch wide wheels , 5 inches of backspacing sits the tire/wheel combo even with the flares and all you have to do is the lift and pound over the pinch welld
3.7s inches of backspacing will cause a lot more issues with rubbing/ turning etc
Plus get ready for a regear as well
I run 8 inch wide Moabs on two of mine , they have 5 inches of backspacing and work great
even 7 inch wide wheels the best backspacing is 4 inches when lifted
as far as fitting over the calipers, black steel wheels will, aluminum will not unless you do have outlandish backspacing on them
Not sure what type the PROCRAP 7069 is, check out Summit or Jegs
Have better parts than PROCRAP does
