having had both setups installed; tein CS v.2 with UAS, and now Airrunner... my personal preference is the Airrunner. im sure that doesnt surprise you after reading everyone else's responses... my reasons are pretty much the same as those already mentioned so no need to repeat.


as far as your question on the psi goes... you really have to find out for your self.. air suspensions are touchy things man.. outside air temperature, load weight, initial parked height, bag size, rim & tire size, offset, drop, etc all play a big factor in psi you need to have dialed in before you take off safely without the risk of ripping off a fender..

ie: you could have your front bags set at 92/92 and rears set at 70/80 rolling at the perfect drivable dumped stance all day, then park for the night when its like 90 degrees out... wake up the next morning when its 60 degrees and go to lift your ride up from being slammed on its face and that same 92/80 might not even lift your car up off the ground at first until you cycle the system all the way up then bring her back down.. even then the psi/height will vary as temps vary.. just like if you pile 4 other people in the car theres really no way of telling whats "good" psi until you check and adjust, get out the car, check and make sure again, then get back in and adjust some more.. this PITA is why most people eventually opt for the manual height sensors that read your actual height off the ground, not just the pressure in the bags, like the usual digital or manual gauges that come with most air setups.. this add on is key IMO but it can be big money esp if you dont spring for it and make it part of your initial install...

on another note, if you park your car and leave it at ride height instead of slamming it/fully airing out, your system should be able to keep the car at the height you left it providing everything is solid and you have no leaks.. you may have to add a little air to get it back to preferred ride height if its been sitting for weeks without having been moved, but minor air creep can be normal on some setups. it can be tough to get a 100% leak free system. its very important to double and triple check for leaks as you progress through every part of your install to avoid the headache of hunting for a problem after the fact.

long story short; dont ever just hop in your car after its slammed on the ground and air up to what you "think" is "safe" driving psi and just take off.. unless you do a quick "max raise" and dont care that you're riding 4x4 mode, you're gonna wanna get out and check that **** and make sure its sitting where you want, the couple extra seconds that takes is worth it...

 

^^^ completely agree upstategs4! also agree with your last paragraph. It cost me a fender. Thought i was at my "90psi" front driving height, I was sure wrong when it unrolled my front fender....

 

Thats some serious information right there

Whats this that your saying?...I highlighted it. Is this for an electric setup?
BTW, Im running manual

 

i completely agree with upstate. it depends on the time of day and mainly the temperature at the time in which you are either airing up or riding around.. when the bags are warmed up, a good 90 front 80 rear is all it takes but for some reason off a cold start, i need to bump it up to 100/90 at first to get the height i usually take..

 

This is great info. thanks guys.

I do plan on getting Accuair E-leveling down the road...

But for now, simple switches.

So it depends on weather, but a good setup would be 90/90 front
with hot/warm weather, with 80/80 rear.

But cold starts in the morning, wait to cycle the system a bit,
and add 10 psi more than your usual setup.

 

nah man. read my first post one more time... there's NO "correct" or "good" setting. there's too many variables between the cars and the systems installed. yeah sure you may find that if you try out those psi settings i mentioned they might be close to how you want to roll but I'm in no way recommending that you go with those #'s blind. the ONLY way to figure out what YOUR car needs is to get in, air it up some, get back out, look around, and adjust if necessary. eventually you'll figure out "about" where you should set it for your ride, but there's a learning curve.

a note on "autoleveling" setups also: they aren't all they are cracked up to be; namely the majority of the pressure only based systems, because they suffer from having to deal with all the same variables as you do yourself dialing in manually.. if you slammed your car out and hop back in and hit the "autolevel/ride height" button, that doesn't necessarily mean at all that after it's done auto filling the bags to "correct" psi that it's actually sitting
where you wanted it/set it to/is safe to drive. basically, just because the psi on your gauge reads what you set it to as "ok" for ride height, the computer stops leveling out and "thinks" it's done it's job... if you review my first post however there's many reasons covered why this setup still has a lot of room for error. and when you roll with as close a tire to fender clearance as i do, 3 or 4 psi can mean the difference between tearing your fender off or just happily scraping through your turns

i cant repeat it enough: just get out and check your height if you are raising from a full air out! i don't care what your gauges say, the two seconds this takes can save you major headaches. the only people that will tell you that fully psi based auto ride height control is 100% reliable and accurate are the ones that have a wholesale account with these companies and are trying to sell you a kit lol.

having said all that, the only reliable way you can really avoid getting out and double checking your height/psi settings before you take off is if you have one of these kits worked into your setup:

(a little over $1k)

http://www.accuairsuspension.com/pro...kerswitch.html
(around $800)


there are a small handful of companies that will sell these setups without having to buy the entire air suspension kit from them (you can purchase the ones i linked above separate from a full kit)... it seems to me that the Accuair is the easiest one to add to a pre existing system. i have the Easy Street AutoPilot Digital Control setup (with "auto leveling") worked into my AirRunner suspension system and im still planning to go with one of these Accuair e-level kits in the near future because im tired of the inaccuracy of "psi only" based height measurement... if anyones got any other suggestions before i drop another grand, hit me up with a PM!

good luck

 

also check out this link:

click on the "Leveling Systems FAQ" button on the left of that page. good info there comparing height vs. psi based leveling kits.

 

PSI on the guages are more accurate, when deflating from 100-80 than it is from 0-80

upstateGS4

Thanks again, for the very informative info

and links

I will definately take the time to check the heights, dont want to damage or scrape the fender...

 

just wondering..... never really considered air susp... but for LS430 how much would be looking at cost wise for air runner ... c install..... and what r some of the better shops...


thanks..

 

i been running UAS air bags on tein cst with accuair e-level , tein edfc and the system runs perfect....no problems at all...anyone local to bay area may check out my ride, just pm me

 

it varries..

but i recommend having 5 of your friends over n just test it and record what PSI it your bags need for You... You + 1.. You +2 etc etc and just have that paper handy when you take passengers.. and if you get a heavy fellow just give the switch an extra tap LOL

 

I would say it would be 5 K installed, for a basic airrunner kit. But some people also get upgraded stuff (instead of dial gauges, you might go for digital etc...) so it ends up costing more.

So I would say 5.5 K-6K, just to have enough.

Yea, I think I will have to do that.

With your air suspension, how much did it vary ?

Just another question:

When an alignment is done at a certain height, would a couple of psi difference (+ or - ) make for camber wear ?

 

Got another question :

For the dampening adjustment on airrunner, there are 1-4 levels.

How do you change them ?

What is the difference between level 1 and level 4 ?




thanks
