I have not tried yet off-road but without 1,25" wheel spacers rubbing the sway bar on maximum turn and flex is 100% sure. There is only about less than 1/2 inch gap. I do not have the quicker disco´s yet and if I use the wheel spacers I definitely cannot go legal here. Too wide. I will be dissappointed ($$$) if I have to think of a new suspension system 4" as this does not seem to be enough?
What do you mean you have 3/4" extra BS? Do you use wheel spacers too? Your rims claim 3,25BS and mine 4". sorry I do not get it.
I sent you a PM.
But also to add, I always disconnect offroad so there's nothing to rub and the suspension can fully cycle. It makes the ride a lot better and the jeep much more stable.
I'm surprised that you could rub your stock swaybars offroad though. If you're only rubbing them at full turn during a bit of slow rock crawling, I woulnd't worry about it. On road would be more of a concern.
What I would try if I were you, is take a wrench with you and disconnect the stock swaybar with a hammer and see if it's a problem. And if you could post up pictures or describe where the stock swaybars are rubbing, that would be good too.
Honestly though, rubbing is only a huge concern is there's enough pressure to either bind the suspension or break something. On road, rubbing can be an issue. Before adding my adj. trackbar, my stock tires rubber the inner sidewall on the frame. It didn't take long to notice. Imagine what would have happened if I let the sidewall of the tire continually wear away as it spun.
So, it really depends on what's going on and how severe it is. A little rubbing in some situations isn't worth worrying about.
