Ok.
My wheels sit flush, as in borderline flush. Seeing as you dont want to go past the guard then you will have to try and match those wheels or run too much and then you will have to run camber to get them into the guard.
My and your wheels are exactly the same, except for the fact that you 0.5" less on wheel width.
So by me using the good old offset calculator that seems to be a unheard mistery, you can easily see that you have 6mm space between your wheel and guard. Therefor if you want the flush look you need 6mm spacers. And im pretty sure you cant get those.
