You didn't say he should run more than 4.75" of backspace on the front. Which is exactly why your information isn't accurate. With a 17" wheel you can run more than 4.75" of backspace, and you SHOULD.
You can run 17x8's, with perfectly stock suspension, with a 5.25" backspace and 245/45/17's and not hit anything. Not the frame, not the fender, nothing. You can't run that much backspace with a 14 or 15" rim because your rim will hit the UCA. So, when you said this
your information was in fact inaccurate. The OP's first post said he wanted to run 17's, which will let you run as much as 5.6" of backspace, even with the stock suspension. You can't do that with a 14 or a 15" rim.
