[QUOTE=Snuffaluphagus;6015397]First of all ide like to thank Kenny for posting all this info up - Ive been debating on doing air suspension for about two years now and im finally to the point where im going to take the plunge (my gf says thanks kenny - she thinks its a waste of money )

But ive got some general questions from a noob here that has never dealt with air suspension at all.

Ive thought about it and decided I shall take your advice and get analog air gauges and your kit you posted in your second post - which brings me to my first question. I'm sure they will seem quite stupid but im excited to learn and do the install myself .

1: Where abouts might I buy analog air gauges? I looked on the AVS website and I can't seem to find the gauges specifically, would any air gauge work ? I've used some generic types before including tire air pressure gauges but i'm not sure if air suspension will require a special type. i dont know about using tire pressure gauges or anything like that. i have always just stuck with air ride gauges. here is a link to avs's gauges. there are many other brands than just avs as well.

2: Just a little confused on your second post shopping list - I understand that you would have to do two orders of the rear/front bags - but what about everything else, would we only need 1 compressor,1/4" Electric Valve ETC? the front bags and rear bags on this car are different. the front ones are the very last thing in the #2 shopping list post. you need 2 of those *left and right* and then the rear bags are up a little above that in the list. also you will need 2 of those bags. only 1 compressor is really needed.

3: Do you not need cups for the rear bags? - Also from my understanding the bags (front/back) should just go on the shocks where the spring goes I presume? the cups are listed in the shopping list of stuff to get in post #2. the front bags slide over the struts where the springs would go. the rear bags get mounted to the cups and then go in where the spring would go. *which is in a spring bucket, not on the rear strut*

4: Kinda going along with question two - for our fittings how many of what do we exactly need, i've read through all the pages on this subject and haven't found how many we need (I could be blind and or stupid haha) I'm going with the 1/4th fittings like you recommended for a nice slow drop. your not blind and or stupid. the reason you dont see a list of fittings or even a number of how many to get is because there is abosolutely no way i can explain which ones or how many you will need. it depends on to many things (what size lines/valves you are going to run, where the valves are getting mounted, how many valves you are using, if a water trap is getting used or not, which way you plan to run the airline) theres just to many factors. what i usually tell people is to get a peice of paper and pen, start drawing, draw in a tank, valves, bags, compressors, and then figure out where every fitting is going to need to go. keep in mind how you plan to run the airline from the tank to the valves to the bags, do you need to turn a corner? if so you need to get a 90* fitting. NEVER try and bend airline to much. if you kink it, you NEED to replace it. becuase it will fail on you very fast.

5: When you talk about running "do i HAVE to run 8 valves?" do you mean the 1/4'' electric valve?(meaning eight of them) sorta like this product but their just an individual item not grouped? if so I believe I understand what they do and how they work. yes im talking about the electric valves. and you do not NEED 8. you can run 4 and be just fine. you could also run 6 but running 6 is just to confusing to explain to someone that doesnt really know air ride.

Sorry for all these questions I hope it didn't make anyone's brain explode on how "newby" these questions are - I'm more of a hands on learner and I know if i had these parts and everything in front of me I will figure it out - But i would like to get some of my most troubling questions out of the way before i actually go through with buying the pieces to start my doomsday of diggin into this project - WHICH I would like to point out, If I accomplish this project I would like to do a write up on it with pictures and all with hopefully kennymo's help and any others if they wish![/QUOTE}]

hopefully that answered your questions. if not just let me know. i dont check this forum too too much anymore because im done with the g35 and selling it soon. but when i check it i will try and help as much as possible

 

yes the checkvalves in the leader hose can go bad. the way to see if thats the problem is fill up the tank to your max psi that your pressure switch goes up to. leave the leader hose attatched to the tank, but take the compressor off the leader hose. so now you should just have the leader hose hanging on the tank. take your thumb and stick it over the hole on the open end of the leader hose (sealing the hole) leave it there for about 20 seconds. when you pull it away you will either hear a rush of air or you wont hear anything. if you dont hear anything the checkvalves in the leader hose are ok. if you hear air come out. they are bad. also how old is the kit? valves do get dirty and they dont seal fully anymore, which does cause leakes that are hard to find. to fix that you just take the valve apart and clean it up, making sure it is FULLY dry before putting it back together and on the car.

 

I am about to order the UAS kit but I am running OEM shocks. Would it be okay to use Tokico HP blue shocks? Truthfully, I don't really care about the comfort.

 

yes that would be fine to run blues

 

Hi Kenny. Thanks for this thread it's been very useful to me. I finally got airrunners installed on my G. What considerations do I need when taking the car to get serviced or repaired? Do I need to have the bags air'ed out when the car goes on a lift with the tires off the ground? Or can the bags be air'ed at drive height? Any other things I should be aware of? Thanks!

 

when taking your car to a shop you are going to want them car to be air out while on a lift. put the car in place. slide the lift arms into place under the car. lift the lifts arms so that the just barley touch the car. then air the car out completely. and then you can proceed with lifting the the off the ground. when its time to bring the car back down. drop the lift all the way down to the ground. then air the car back up and pull the lift arms out from undernieth the car.

 

just out of curiosity, what would be the negative factors of having the car lifted while aired

 

Thanks for the info and help Kenny! I just had my car serviced at Infiniti and I asked them to do what you mentioned. Everything went well. Thanks again!

 

9 out of 10 times, nothing negative will happen. but i have seen people leave the car air up and then lift it and when you go to set it back down, you chance pinching the bag on something or over flexing it while its in the air. like i said 9/10 times nothing will happen. i just tell people to do it that way just because better safe than sorry.

 

Before I put in my rear bags I tested to see how low I could go with just the shocks in and the shocks are just to long. So if anyone is on OEM shocks thats why you cant go low in the rear. Are the 350z shocks shorter, or what shocks are shorter than the OEM?

 

take the rear shocks out. i hardly ever ran shocks on my trucks, and most people dont. i really dont know how the rear of a g35 will act with no shocks in the rear but i dont imagine it being to bad. call it ghetto, call it unsafe or whatever you want. but it will still work and with air bags you really dont need them.

 

Ok....Dumb question. Is it safe to run an air suspension with coilovers on the occasional track or autocross? I understand handling will suffer a bit. So I'm just wondering if it has been done?

 

yea its safe. a lot of tracks (mostly drag strips) if they know you have air ride, they will not even let you run the car though.

 

Thanks Kenny for the insight. I have a couple questions. I live in Texas and the climate as of late has been blistering hot. We're pretty much in a drought. I've heard a local G35 driver who switched his airlines out to aluminum piping. Would you be able to recommend where to find these lines? Also, I notice some G folks run the airlines underneath the car. Is it possible to run them in the car under the carpet to help protect the line somewhat from the weather?

 

Hey kenny im wondering if you can come to the bay or something n help me wire my dakota gauge for my airride... Just wondering because tnt already prewired the wires for me...
