Here's a pic of your car and mine that I edited to see the wheel gap easier. My car has a firmer ride than stock but is not harsh and has way less suspension travel.



your is lower,and front and rear looks even.nice car...
I played with heighs,make every corner close to 0,and even using measure tape,to make from floor to wheel arch 28.5 inches...when I make ,run car and drive and next time all corners in different heighs.
all suspension bushings, arms,with regular wear..but nothing worn..
yes,it reacts to Height ****.raises and lowers.
I am worried if rear struts are worn,as they hits down hard at bumps.looked at history..on fronts I have 50k miles,rears 110k miles

For the warning lights you just have to leave the actuators on top of the shocks connected to their wiring harnesses and secured in the general area where they were before. BC Racing has coilovers for your car if it's RWD.

Awd is no different, the most you'd have to do on either one would be to pull a couple of fuses and maybe disconnect the compressor and suspension ecu. I've never done that to mine or any other but the rear oem non air shocks should work andt it would need aftermarket for the fronts because of the axles.

Default Ride Height adjustment

Hello ,I read old posts about air ride adjustment, but cant find an exact answers...how to adjust and lock the settings..
when using techstream,air suspension, active test,I am trying to adjust height,but as long as I switch to another wheel,previous wheel goes back to own settings...
There is offset height adjustment option,but I am scared to mess there...
Anyone knows how to do that properly?

Mechanical adjustments on the height sensors or the Data System controller, those are both exact answers but will not satisfy you I'm sure. The height offset is the 1 inch difference between height high and normal height, again exact answer and this will do nothing for you. You would have to have engineering level access to TS and have some serious coding skills to change the suspension system like that.

I have an ls460l 2016, and last year developed the control arm issue, but continued to be driven until it was diagnosed and repaired in an independent mechanic. But the ride is still not as smooth as before, the bushings were replaced and tires replaced, took it to 5 different mechanics and they all say nothing is wrong and the shocks are fine. Anybody had similar issue? The ride isn’t terrible just not what it was, like a low frequency vibration felt in the seats and steering wheel mostly at higher speeds

The height offset procedure you were in earlier might have made a small difference to the height high setting when you used it to raise the car but remember you’re dealing with an inch from the normal height it raises not lowers plus you don’t have the oem numbers to input. I don’t know how to explain it any further to you, might be a good idea to take pictures when you’re attempting to change things so you have something to go back to when they implode.

I didn't use that offset feature,as it overwrite ecm...
Though that other active test feature is helpful, as some guys posted their results...but on my experience, it goes back to factory settings...as soon as I release 1 wheel adjustment button, i hear compressor is running and car ir rising.someone posted this...

Did you go with OEM parts? I had a similar issue with my 2010L. I decided on aftermarket bushings/control arms instead of the expensive OEM on my 13-year-old 460L at the time, at an independent shop, new alignment include. The ride was almost as smooth and probably smoother if I went with the OEM parts. I also notice a small vibration in front seats/headrests around 60 mph. I had all 4 wheels balanced and the vibration stop. That pursuit of perfection means expensive Lexus visits.
