planning on getting some bilstein 6112 and 5100 on the rear ,,285-70-17 and wheels with a zero offset ,, will this set up rub?

 

5160 is Bilstein's equivalent to 6112 for the rear. They are often sold together, and come together on Pro's.
The rear already rides worse due to stock hangers.

I do not see the point of getting a 6112 for the front that has more dampening (2.3") and not getting that for the rear, having a pencil shock in the rear.
285 70 17 33" is common to see what's needed to avoid rubbing, also factoring in wheel dimensions.
Any upgrade like that will tend to be closer to rubbing, and need other things done to prevent that.
There's also tall skinny tires, but sometimes only come in a heavier load rating which may not be ideal.
