A curious thing about those new tires...
I bought a heat gun and some plastic rivets to pull the front fender liners out and I intended to bend the pinch weld over, reshape the liners, etc. I noticed right away I had no rubbing on the street and figured when I got to Moab, I'd spend the evening doing that whole process, because surely once it started flexing around, there would be problems. I decided to wait and see how bad the rubbing was. After running Hell's Revenge and including Tip-Over-Challenge, I have very minor rubbing in front, just enough to rub off the mud, really. The rear is my problem. The crunched tire radiuses forward enough that on both sides, the tires popped the rivets out of the door-mounted fender flare sections and popped the ends of the plastic rocker cover off. Not at all what I expected and not sure I'll do anything about it. Though eventually I may ditch the rear SL setup and go with the BDS adjustable control arms mounted in the stock locations.

Ok I have to ask this....do you think your issue with the tires is due to the lift or due to your wheel set up? Reason I ask is becuase I have been talking a lot to AEV and they swear up and down that their Pintler wheels will have no issues whatsoever with the 285's. They use 17x8.5 rims with 25 mm offset (~5.3" backspacing), which for the life of me I cannot find in any other wheel that will fit our rigs. I remember reading Mikes writeup on the lift comparisons and this issue was very clear on the rear control arms.

The issue with the rear tires rubbing is definitely with the lift. The rear control arms are only slightly downward from the mount to the axle when the Jeep is in a flat, static position. When the compressed side of the axle moves upward, it almost immediately starts also moving forward from the short radius of the control arms. Another problem (in my opinion) with the design of the SL kit is the relatively large rear lower control arm brackets. They hang me up on any ledge larger than about 13 inches. The passenger side bracket is beat silly, I probably should take it off and straighten it out. The BDS setup (and I'm guessing the method of setup Mike is talking about) would alleviate both of these 'issues'.
I'm running (as I'm sure you see in the pics) Rubicon Moab rims with 1.5" spacers. This is probably very similar to AEV's specs when using the Pintler wheel which of course doesn't require spacers. The rubbing in the rear could also be caused by the difference in some tires even when listed as 285/70's - the KM2's seem to have relatively deep tread blocks. They had 400 miles on them when I went to Moab, they probably won't rub at all after 20K.

Sounds familiar indeed! This is the issue that Ross of GetLost fame accused me of lying about on the other forum: the current Superlift design forces the tire to radius forward in the well far too quickly, limiting wheel travel and causing rubbing problems and the associated damage. (This isn't, as I've discussed elsewhere, as big a problem as the full so-called 4" BDS kit had, however, but those kits are no longer available.)
And, yes, this problem is exactly the one my modified kit is meant to alleviate, while also getting rid of those related brackets. I hope that a kit with the design I have hits the market soon.
Utilizing the old BDS adjustable arms -- so long as they're the "bent" ones -- is a sensible solution in the meantime. I had one of my BDS arms fail, but my experience with BDS's manufacturing quality would indicate that this was an exception rather than a rule.

Good to know, Mike. I have new BDS lower control arms still in the box, but I've been hesitant to install them until I can eliminate the upper control arm brackets as well. I haven't looked for BDS adjustable uppers yet, but I guess that's the next step unless your kit comes out soon...

I assume you did not have this issue when running the 255's? Might be a good choice to forego the extra 0.5" ground clearance and wait till Mike can give us a solution :-)
What do you think would have happened if you were running rock sliders? Do you think that type of rubbing (on the plastic rockers) would have given you major issues if you had a slider installed?
