I needed to take an inch off the rear bottom of my wheel well opening due to the bigger tires, wider stance, and no body lift. Been searching for a year or more for decent fender flares - none on the market wider than an inch or so. I really wanted two inches. Noticed a rubber bolt-on product called Flexy-flares that comes in four styles, about $80 from Autobarn for enough to do all four openings. Cut the fender today and installed the front flares and they're not bad. I thought they would be 2-3 times as lame as they are, and I might keep them on for a while.
