Quick help needed please

Hey guys Im looking at some 17 inch rims in a 10.5 inch rim with 6.9" backspacing do you think they will fit in the rear? The fronts have a 5.95 backspacing, Im more worried about the rear tho, the rear tire size is 315/35ZR17's, would I have to get rid of the tailpipes and run dumps, flip the quads etc? Thanks.

I did a search and found that the quads do have to be flipped or removed on the rear even with the stock ride height, search function is good sometimes
