I thought I would add my experience to this thread as well.
I ordered the foam cell pro kit with prebuilt coilovers and 2" performance springs front (0-110lb) and rear (0-660lb). It's not that I needed the performance spring capacity in the rear (yet), but I wanted to maintain rake for when the vehicle is actually loaded for a camping trip. The only other option would have been the 1" comfort spring in the rear. I do plan to add sliders and drawers, and possibly a roof rack, and I wanted that rake. I also added SPC UCAs.
Install took me probably 14-16 hours of labor in my driveway working leisurely over the course of a few evenings. I don't have air tools or a lift, and my only other lift experience is my FJ40 a couple years ago. None of the work was very technical and I think any capable shade tree mechanic can do this themselves if they don't want to pay shop labor. But a quality LC shop can fine tune the coilover height and your alignment after install to help tire fitment. I will mention that the lift kit came with essentially no instructions. I relied on the Ironman GX lift install video, the Ottram 200 series tough dog lift install video, and
this thread for guidance.
LT285/70/18 ridge grapplers on factory wheels (60mm offset).
As you can see in these numbers, I got quite a bit more lift than what was advertised. I don't know if Ironman is to blame for that, or my old suspension was worn out. Track width with factory wheels looks too narrow for my taste, but the vehicle stance looks great now. I really prefer the ride over the stock smushy suspension.
However, I am rubbing the KDSS arm and the passenger side stabilizer bar at full lock:
And my CV angles look pretty steep:
If a good shop did the install, they might have built the coilovers to a slightly different height. Then maybe the track width wouldn't have narrowed as much, which might prevent at least the rubbing on the passenger side stabilizer bar? I counted the threads on my coilovers and they seemed to have been built to the same height, but I have received at least one message from a guy that got one coilover 1/2" taller than the other. I have called a couple well known cruiser shops and they basically always install spacers with factory wheels to widen the stance and help clear the UCAs and KDSS arm.
I am now debating some options. Diff drop and/or KDSS relocation kit. Adding spidertrax spacers or seeing if Discount will take these tires back and switching to Icon wheels (25mm offset) and 285/75/17 ridge grapplers. Some guys report almost no rubbing with Icons and 285/75/17s, some still rub in the same spots I am.
