I am new too this forum but I have been lurking for along time.
Jeep is a 2013 rubicon with rock krawler 2.5 x- factor kit on 35x12.50 Toyos.
I am rubbing on the front bumper only when off-roading on 3/4 to lock when turning. Does anyone else have this problem? And how did you fix it?

 

what wheels are you running? backspace?

 

4.5 inch back spacing method wheels

 

It will self clearance......

 

hmmm....have not heard of anyone having issues 35's rubbing with this bumper.

have any photos at full flex showing where it rubs?

 

I would say the ace mid has the same dimensions as the factory bumper. It dosent look like there is any more clerance buyilt into the design.

As soon as you add a mid arm kit with arms that are a little lomger than factory you are going to rub.

Maybe a couple fender washers between the bumper and frame at the 8 bolts attachment points?
