Can you post a picture from the front and rear along the side? Looking for perspective on how these fill the fender wells vs stock.

That helps a lot, but I meant more directly in-line with the edge of the tire. I'm curious where the tundra arms put the edge of the wheel in relation to the fender.
Thanks

Awesome.. thank you!
How bad is the high speed road handling? I can't imagine rolling with no ahc or kdss.
The LC handling with kdss valves open vs shut is night and day, massive lean vs very flat/way too good for a lifted pig on 34's.

I had to double check my notifications on this one, to confirm that your name is in fact, TerdRocket. Thanks for the laugh, and really sorry for getting off topic. Also, beautiful great dane! Sorry again. I'll show myself the door now.
I don't want to take away from this thread as I think it's really an awesome thing to be able to make the LX570 more tailored, hardcore, and more specific to what one may want to do with the vehicle. Or for someone that has an example of an LX with AHC completely clapped out and not worth fixing. Credit to @turbo8 for solving part of the riddle.
I agree it's worthwhile for someone to enter this eyes wide open as this wouldn't be an "upgrade" in many respects, considering AHCs magic ability to tailor and be well rounded for just about every use case. With Toyota/Lexus levels of durability. Specifically to your point, an AHC vehicle would destroy any statically lifted 200-series in handling by virtue of its more optimal geometry ride heights, AHC (KDSS on steroids), multiple spring rates on front axle which can be stiffer and softer than any single spring, constant height, fully dynamic AVS active damping control, and sophisticated integration with engine and steering modules.
Yet with a sensor lift and on demand high, it could be lifted to comparable or greater heights than a static suspension. Without having to deal with the day to day compromises.
On the 100-series, it was cake to rip out AHC without codes. Everyone did it as soon as they got the car. Until there was a better understanding on the boards of what AHC truly was, how to modify it, and the capability they gave up. With pangs of regret from those that assumed it was just another air suspension. It's now different with many more attempting to keep and further augment it.
In my eyes, AHC is the star of the 200-series platform. I wouldn't own one without it.
Without cluttering this thread further, relevant discussions so people go into this eyes wide open:
80 series guy needs advice on 200 series vs. LX 570
Guys I'm looking to get something newer. I know cosmetically the differences between the LC and LX but anything significant other than that? my planned mods/goals are: Have a dependable rig I can drive off-road cross country with my family( My 94' is now 23 years old) Long arm suspension...

LX570 AHC “Basics” - Added as sticky thread for AHC Issues
Point of this thread is to serve as a repository for 200-series AHC info, including LX570 and LC equipped with AHC (in select global markets). Let’s begin with a theory. The 200-series LC (without AHC) and the LX570 (or LC with AHC) are like New York & LA. LC “purists” are like New Yorkers...

With the increased width, spring rate, and high pressure shocks. the high speed handling is pretty predictable.
Completely different than removing a sway bar and still use the stock springs and shocks.
The feeling isn't for everyone, but I always have liked my off-road vehicles to handle this way.

@turbo8 Thank you very much taking the time to do that.
p.s. I haven't ran a front sway bar on my 100 series for probably going on three years, granted whole different front end on multiple fronts. I do run extended links on my rear bar and check the bushings every few oil changes. I have put on over 40k miles like this, towing 3k to 5k lbs loads across multiple states at various times with no issues.

Where I was going with what I asked @turbo8 to measure for those of us wanting to keep AHC but potentially wanting to do the Tundra front parts swap and or just beef up the front end to offset weight from a bumper and or winch combo is commercially available spring options. There would be some additional measurements needed that depend on the upper coil spring seat area but something along the lines of this should be about right. Something in the 300lbs/in to 350lbs/in should offset that weight and still maintain all AHC functions.

I'm running the ARB Summit, plus a second battery, ARB dual compressor and BB skid all up front, and thus far AHC hasn't given any indication of strain or difficulty.
Just as fyi.

Little update
I removed the pump and cut out more hardlines.
The next morning my dash lit up like a Christmas tree. It threw abs and vsc codes.
I reset the codes and went on a 500 mile trip through Mojave and Joshua tree preserves. No codes.
Tonight after work I was hooning around in the desert getting the abs and vsc to activate, to see if I could get the codes again. They both worked as designed.
I'll keep you informed if the codes come back.
Besides that, this thing rides just as nice on road and much better off road.

Thanks for this by the way; definitely an important piece of the puzzle. Do you think it would be possible to fit solid axles on the LX? I was thinking 5-10 years down the road after this LX, that i would build something with portal axles, which i believe has to go on solid axles (could always be wrong though). A portal axle LX would be ridiculous in terms of capability and luxury in one package.
I have seen portal axles + AHC (4-8 inches of lift on demand, maybe 2-6?) on a 6x6 70 series from Patriot Campers (Australia) and i was thinking that setup on an LX would be ridiculous.

That is BADASS.
