Spacer advice, what area will rub?

Hi Guys,
Sorry if this is a double post, but there are so many spacer posts out there when I searched!

Anywho, I'm running stock TRD wheels with Goodyear Duratrac 165/75/16s I believe they are.

Rubs just BARELY when I crank it left all the way, but it's not much of a concern.

I've been thinking about picking up a set of the spacers everyone here seems to love. I'm just curious if they will rub? I'm assuming it might, but what area rubs? Is it the front inside part of the bumper? (plastic?) Removable?

1.25 rub just as much as 1.5?

Thanks for your advice!

 

Just level the front out with bilsteins and that should take care of the rubbing

 

oh! Tempting solution actually
That was the next thing I was hoping to do! Been keeping my eye out in the marketplace section to see if any were gunna show up
