The higher you lift an IFS, the closer it will bring the tires to the UCAs. I'm surprised you rubbed with 265s, I'm guessing you must not have had stock rims? You can't get spacers in your state?! I never knew they were illegal in some states, I can't believe they're legal here in CA, we're always the first to lose our rights before the rest of the states! - especially if the law makes no sense.
He could buy wheels with less backspacing than the wheels he has now and that would give him the same result.
