Mate I probably know as much as you do about it or you probably no more lol. I have only read that about the front should be lower then the rear ??? I know when I look at the standard 100 series land cruiser they are extremely noticeable in regards to this, they really look like there nose diving especially under brakes...Myn has the standard suspension in it and is noticeable the front sitting lower then the rear, but then when its loaded the bum squats down a bit lower the the front, i really need to update the suspension as its annoying and i dont feel like it handles any where near as good when really loaded, especially compared to both my old 90's that had OME fitted, they rode extremely well both loaded and unloaded and with out the need for airbags in the rear coils.......
""Is it an IFS trait? I'd be interested to learn more."" I would say a definate yes
