5100 - Sway bar relocate

I searched and couldn't find the answer, I applogize if this is a stupid question.
I have the 5100's set at 1.75 currently with LR UCA's, it awesome. I just got new 32" tires and want to go to the 2.5 inch setting now. Everything I search looks straight forward, but I'm confused about the Sway Bar Relocate, do I need one? I'm assuming that they are only needed if your coil drops below the sway bar itself, with the 5100's (stock springs) the coils are well above any contact point of the coil. Again I'm assuming that the SBR is only needed to extend the SB forward enough to clear contact with the spring.

Thanks

 

you should be fine without one

 

you mostly need it if your buying new complete coil overs because the springs contact the sway bar. but with the 5100s i had no problem at all
