"Everyone" DOES NOT say 4.5" backspace is correct. As the other posts read, measure YOUR car to see what space you have. I can't stress how important this is.
I see all these comments about "grinding", "bending", "cutting", "tweaking", "rubbing", when a little time spent measuring, researching tire section width for a specific brand & size tire, and sourcing a wheel/tire combo with the correct backspace to center it in the wheel opening, can save you so much grief and wasted money on a wrong combination that can look strange and worst of all possibly be unsafe.
