Accidental Fubar mounting wheels on a 5lug

First and foremost, I did a poopton of research before I started doing my set up for my little daily driver 5 lug, which i wont be using in any real abusive situations...definitely no offroading.

I bought a set of Rock Crawler Series 51 - Black wheels.. -19mm offset, 15x8, compared to our stock 5lug +45 mm. Which sticks my wheel out 4.1'' further than original so no there would be no tire rub, I am running 32x11.50's. There is tire rub still at extreme full turn on the sway bar (this is the minor issue).

I'm pissed at myself for not noticing this, but it was almost inevitable due to no pictures of the inside of the wheels when i purchased them..



4 wheels parts said they would fit, yep, they do not. Because of that inner lip, the wheels rub on the bottom lower caliper bracket that holds the brake pad.

Its rubbing bad on one side, the other not so much. My 3 questions:

Do I trim the lower caliper bracket?
Do I get wheel spacers with studs (I have to because they are already pretty short due to the wheel design)
If i get wheel spacers, should I buy all four or just the front two?

Thanks for any help/suggestions.

 

If they said they would fit I would return for the right wheel. I would not trim/cut or modify the caliper bracket. If you get spacers I would get all four
