I'm in the same boat here.
2005 LX470 w/150k and the AHC system is leaking from the rear drivers side line. The RAM's (can't call em shocks) are whooped and I just ordered the IM stage 3 kit and waiting to install. Adding AHC fluid anytime the system shows me it's low (roughly every few weeks) so it doesn't go into limp mode. The accumulators are good (measured a difference of 13 before the leak started) and I may try to save AHC bits, but just want a regular suspension now. Good info as I was curious about the difference in ride.

subscribed, thank you

Hey guys, just got the IMFC Stage 2 installed today!!

Foam Cell Pro 2" Suspension Kit Suited for Toyota 100 Series Land Cruiser/Lexus LX470 - Stage 2 - https://ironman4x4america.com/foam-cell-pro-2-suspension-kit-suited-for-toyota-100-series-land-cruiser-lexus-lx470-stage-2/

The overall driving impression is that:
  • Highway: Factory Most Comfort to Comfort Setting compared to stock
    • This is super smooth! Closer to the most comfortable setting on the stock with nob turned all the way to the left
  • City Road: Factory Comfort to Sport (Not the Sportiest setting with nob turned all the way to the right) compared to stock
  • I have a 1" rake between the front and rear
  • ~2" lift all around
  • I ended up getting the differential drop kit
    • As you can see the Rack&Pinion is almost straight

This is exciting as I was getting a little apprehensive about ditching my perfect AHC for the FCP lift sitting in my garage. I really enjoy it in the Comfort and Comfort +1 settings so to hear that this is generally the ride from the IM kit makes me very happy :) I'm diving into it tomorrow and will post up with my own driving impressions once I get an alignment done on Monday.

How did your alignment come out?

Alignment was no issue. Also the comfort +1 is a high way feel. I saw on regular roads it is comfort or comfort -1

UPDATE ON IMFC
----------------------------------------------------------------------------------------------------------------------------------------------

After driving around in LA here are some of the things I noticed with the IMFC:
  • Minimal body roll when turning
  • Minimal head dip when breaking; even with hard breaking
  • Sportier suspension feel at speed above 70mph; always felt the stock suspensions gets a little bouncy around 70mph
  • I would probably say overall the IMFC feels like "comfort to comfort -1" on the stock suspension

By the for the AHC delete portion:
  • Removed AHC relay in the engine bay
  • Removed the AHC 50 Amp in the engine bay
  • Did NOT remove passenger AHC fuses
  • As a precaution also removed the plug to the AHC setting module in the center panel (this is not necessary)
