Air suspension and sport vs. comfort

My LS400 had almost 170,000 miles on it, and one air strut was showing signs of failure right at the end. LS430 was around 100k and no issues. I'm sure it's like anything else. Depends on climate, garaged or not, the sort of roads you drive on, etc.

You also have to consider that if people aren't having issues, we're not going to hear about them here. But if all 20 people who ever had problems within 50K miles post here, it's going to seem like this is a wide-spread issue that should steer people away. I'm learning to take all of the bad reports I see here with a heavy grain of salt as everything (even standard strut/coil suspension) will fail given enough time.

Yep, very true.
This is a widespread issue though, as are the control arms on pre 2011 cars. The air suspension is not a unique problem to Lexus, air suspension systems in general are problematic. I've had long conversations about this with my mechanic who has a long history with Lexus.

Largely that's because of the control arms. Air suspension is an issue regardless of year, and most LS460s don't have it to begin with.

I believe I read they worked out most kinks halfway through the 2010 production year. Thankfully mine falls in the later half.

Oliver Enterprises (Jason), I call mine sport-suspended because it has more aggressive computer settings for the dampers with six-piston front brake calipers and larger rotors all around.
It's officially called "touring".

See, the computer I got for the suspension was for the regular air version. I could probably play around and record how it behaves in my Fakestream over a section of road, but that's too much work.
Also, I'm unusual in that I'll dig into any automotive 'system', regardless of make/model/year/original cost, except automatic transmissions.
Those are full of magic.
Correction...I'll mess with valve bodies and the like, but taking them apart for seals/clutches/etc? Nope!

FWIW, the rear brakes on "our" sport model are the same as non sport LS460's. Only the front brakes are larger.

You are incorrect.
Rear brake rotors on a standard suspension car are 12.4". Touring are 13.2".

"Fakestream" is my name for cloned TechStream out of China.
I saw not one thing on the dash, though I have an '08, but it definitely felt way firm. 17s, all-around, it's plenty unforgiving. The fake TechStream confirmed it.

Hey mckellyb
Although some dealers tried to advertise the "touring" models with 6 piston front brake calipers the word on the street is that they didnt actually come with it
They are still 4 piston calipers but seem to be different in some way as they have different part numbers from the standard brakes.
There has been alot of debate about this so maybe you can check them at some point and find out forsure

Hmph. This never posted.
And to think, I'm in IT....
Yeah, I can't find any references other than in early writings/testing about them being six piston. Every picture I've seen looking at calipers and parts, they're definitely four piston, just larger.
My front rotors are warped, I don't know when pads were last installed, and I've got five tires coming up soon, so after I drop a couple grand on it, I'll letcha know what I find. I figure I'll do brakes all around. Can't hurt, and drive the car harder than most, probably.

Sport/FSport/GSF all wore 15 inch rotors with Brembo 6 pot calipers. Even the ISF has slightly smaller pad and rotor size. Found this out ordering brakes.
The Touring wears the 4 piston calipers and 14/13" rotors the AWD model has.
And back on topic I wonder how much difference there is in the settings between different models. I think the problem either way is the lack of footprint back there with skinny 8" rims and only 245 width tires. The rear is quiet easy to break loose even with traction on.
