Air Suspension to Standard Conversion?

I know better than to admit anything like that on the internet 
I bought them from sewell lexus online parts, with the club lexus member discount. They're big $$ for shocks, but the club lexus takes the sting off a bit.
The install was <20min per side in my garage with a floor jack and simple tools.
The fronts now feel a little soft, so I'm probably going to buy them and have them installed before long.

Based on my experience, 60k from a set of OEM shocks is quite good. I've had them go far earlier on other cars, so I was pretty impressed -- especially given what we're asking of the rear shocks in the GX, which is quite a bit. They need to control varying loads, ride heights and air spring stiffness, which is a bigger challenge than you throw at most shocks.

and the thing is, even on the RRs, it's not uncommon for them to run for 100K without much issues with the suspension units on the 2006+ rigs. at least with the GX, i can run it for miles on end with peace of mind. gotta love made in japan.
i am lookin gforward to getting some new shocks on mine when the time comes. good choice on the 911. i'm sure it's a speedy lil bugger.

That's exactly it. The shocks don't act much differently than any other car. They just don't seem to control the ride as well over time. With a faulty sensor, you'd likely notice the backend dragging a bit, or feel like the car is bottoming out, but it's more periodic. In my case, I've noticed, when it acts up, I never hear the car level off when I exit. That's when I know it's time to lower the backend, throw in a couple of 40lbs bags of water softener salt, start up the car and drive it around a bit. It seems to "reset" the system for a while, till it acts up again. I don't have to keep the salt in the car more than the short time during the "reset" process.

"Adaptive Variable Suspension (AVS)
AVS is a computer-controlled system that continuously adjusts shock-absorber damping rates to help provide appropriate ride comfort and handling precision. Sensors monitor wheel speed, engine rpm, steering-wheel movement, brake application and vertical body motion to determine the ideal damping rate for each shock absorber. The driver can also select the ride firmness with the press of a button."
So, it looks like the sensors do control the shock absorbers for "ideal damping rate" according to road conditions, etc.

There are few members who have done the complete swap using Bilstein, some of them have done with the Overland 2.0. Here is the website. The 4Rs and GX share the same chassis, if you I decided to eliminate the sensors from the equation. Then you can replace the rear set up with coils and shocks… thus eliminating the need to replace the height sensors every three to four years. You have to remove the Airbags
Overland will not come with the coil clamps so you need to fabricate one for the springs. The clamps are to prevent the coils from rotating and also to prevent them from popping out from severe flexing.
Here is how the kit looks and here is the linkhttp://stores.overlandwarehouse.com/...kit/Detail.bok

I think the height sensors are POT (potentiometer) in nature. When the height change, the resistant change which provides ECU with different voltage. Here is how to check them.
