You’re right! I’ve been using the HI mode a lot in the neighborhood/traffic and I think it only abruptly drops in HI and not Normal.
Mine will level out at a stop light when on an incline/decline but I wouldn't call it abrupt. When I drop it out of High into Neutral while parked it drops sort of suddenly but I've never seen it move that quickly while underway.

I believe that’s normal - mine does it throughout a drive - sometimes at lights, sometimes in a drive thru, or when parking. Small but noticeable changes
I was thumbing through the IG last month when I came across the below pic from a guy I think is on Mud - andrewpounder.
I say to myself and now I'm looking for LX570s on cargurus app. In the IG post he says he only does the sensor lift (like what's mentioned already) and then fit the 35s with some trimming and a body mount chop. This is what I want:

I think that should we keep ours for the long haul I'll most likely end up going this route. Sensor lift, BMC, 34's or 35's on 18" Lexus or Toyota wheels with wheel spacers. I might explore the idea of aftermarket wheels with the proper back spacing and offset so that I can avoid the wheel spacers, but I do like the built sleeper look on factory wheels. Add the Slee sliders and hopefully a light weight low-profile winch bumper of some sort and call it day. I can travel with it, use it as a daily when needed, and still do mild to moderate off-roading without worry or issue.

Here are 285/75R18 Nitto RGs on Tundra wheels with 1.25" spacers. I want to change the Toyota bean logo to the Lexus logo which can be done with some cheap Lexus center caps. I too would like sliders but they are not in my budget anytime soon. I don't think I'd do a low profile winch bumper since I haven't seen one I like. I was thinking even more sleeperish and going with a Trail Tailor hidden winch mount. That with some front recover points and I'm happy. Maybe a roof rack

I love flat racks but I won't put one on until I need it and so far it hasn't been necessary. Tundra Wheels would be nice and like you said, it'd be easy to swap out the center caps. I am not keen on running wheel spacers but I've done it before so it's not the end of the world. I am on the list for the second batch of Slee sliders (missed the email to make the first round) and I am hoping that eventually (within the next year or two) that someone will finally make a proper bumper or low profile hybrid of some sort specifically for the 2016+ LX front end. Half of the push for a winch bumper is to reduce the break over angle, gain clearance, and alter the questionable spindle grill front end. I'd be ok with a hidden winch mount but it doesn't improve the front end clearance/breakover angle any nor does it help improve the appearance haha.
As much as I'd love to go all out and have this hardcore, overly built rig, I just don't see the need when even in stock form they do so well in all respects. I think a LX on 35's that still retains the AHC and has all of the necessary protection and recovery to tackle almost anything I am willing to throw at it should be more than enough rig to keep me happy. I'll either build a more extreme wheeler for next level stuff or I'll stick to my two-wheel off-road toys for anything beyond what I am want to drag the LX down.
Behavior is typical and normal when in high mode.
It's related to the suspension geometry when in high. The control arms are at a steeper angle downwards. When turning the tire or experiencing side loads, this will cause jacking forces on the front suspension. Again, because the control arms are at an angle, side loads can translate to lift. The AHC height sensors detect the jacking of the front suspension upwards and corrects for it.
Part of the reason I dislike statically lifted trucks. All sorts of bad suspension behaviors due to compromised suspension geometry. Sure, they trucks look cool, but I know they also generally drive like...
Succumbed to the voices in my head telling me to lift. Or was it all y'all?
Did a mild sensor lift. Paired with install of an OEM front leveling spacer to make sure I can maintain payload capacity to tow heavy. Along with existing 20mm spring spacers at the rear.
EDIT: spacer part number - 43136-60020
I opted for a mild lift so I didn't max my adjusters. Increase of .75" front and .5" rear was the target. To remove a tad of rake. Balance to maintain as good of suspension geometry as possible as I do enjoy driving hard on tarmac, while getting a bit more obstacle clearing lift.
Measurements from center of hub to fender (net lift from stock):
Measurements from ground to fender w/ 305/55/20 33.2" tires (net lift from stock N height):
EDIT: Added 35x12.5r20s, new measurements from ground (net lift from stock N height):
AHC also has an automatic "extra high" position that is selected by the system when in CRAWL and the system detects a need. It's an extra 20mm (~.75") on top of all those numbers. Easily competitive, or higher, than static aftermarket lifts. Especially when one considers these lifts are constant height regardless of any weight added to the vehicle.

Did you have any left to right variance? I finally figured out how to use the Height Offset utility to get my FR & FL the same.

@radman please let us know how it works.
Planning on posting an extensive how-to soon... I go in for an alignment later today, and I hope they let me check my heights while its up on the level table.
Yes, checked it for a baseline before I touched any sensors. There was very little offset between sides, about 1/8".
Interested in how the techstream offset works.

Hi, could you please share instructions on how you fitted those OEM front leveling spacer? I purchased a pair already but I am quite worried about AHC line disconnection. How to make sure no air is introduced? A simple AHC fluid flush afterwards would be enough? My concern is about air remaining in the shock absorbers. Maybe I am being over cautious...
You need to depressurize before disconnecting the shock or you’ll get a face full of fluid. A simple bleed after would ensure no air. You may need to top off your reservoir.
You got it. Find here:
OEM Front Spacer Install for AHC Suspension
Why: More suspension travel to a full 10”, matching rear suspension travel. Spacer allows more droop travel by ~.75” than stock shocks allow. More front axle payload capacity by pre-loading the front shock assembly for normal heights. This is because AHC relies on two sources for support: 1)...

So if I ran 275 70 18 (33 x 10.8). i don't need to adjust my sensors or add spacers behind the wheel?
But then I can level it with my sensors and get an alignment..
there isn't much LX570 info on the 200 series tire sheet.
thanks

this is an accurate statement.
Thank you. My head is
The fitment tire sheet is just as relevant to our LX, as they're ultimately both 200-series. Anything that will fit on the LC will fit on the LX.
Actually the LX will fit even larger and wider as we don't have the pesky KDSS bar as the limiter on our vehicles.
