You should realize you will loose all turning and compression limits. The further out you set tire that width, the worse you make it. They are using that on steel springs which gives up all the travel range already. The only way that works without cutting a ton of stuff.
To tell you in a different way, I am using a 34" km2 on factory 18" with ZERO loss of travel and turning limits while having ZERO rubbing at any extreme....
This does not work with spacers. It only looks cool but my set -up will out drive any steel spring 35" on the worst trails simply due to it retaining the cross linked air and full range of wheel travel plus higher ground clearance.
The slick way to do this on an lr4 is to just swap in lr3 sized brake rotors, get lr3 wheels, done. Quite easy actually and results in higher performing vehicle that ALSO retains every great aspect of day to day and highway travel.
I have Lucky 8 strut spacers on top of air struts. BFG km2 285/70-18 on factory wheels, no spacers. I tested them w spacers because frankly, it looked so incredibly badd assh but it caused all the obvious problems.
@jwest, nice to see you back here. Haven't seen you post in a while.
Did you see L8 post somewhere that they were on steel springs? I hadn't seen that. The owner of the LR4 in question posts here, so maybe he will chime in.
If you remember some of our earlier discussions, my current setup is very similar to yours. Currently on true 33.3 K02s on Compos with strut spacers, rods, and some of that lift dialed back out via IID. My only rubbing in that config (after all the requisite mods) was on the TR sliders, which significantly protrude into the wheel wells. This is what I recently cut down
On the truck in question, I recall that they had gone to the extent of cutting the inside portion of the wheel flares so that the wheels would tuck in on compression.
I agree that I wouldn't sacrifice our already somewhat limited suspension travel, but I would mount one up to play with and see if it could be made to work.
ETA;. The 35's we are discussing on the truck in question measured out to an actual 34.5x12.5 IIRC.
