Building air suspension please help

[DirtyEturdy]

Hello, so I've been working on building air suspension for my e30 over winter. Of course I followed the build done by white325is as many people have done. I have all of the recommended parts used to make the suspension work except I'm running into a big problem and don't really understand what makes mine different than anyone else's. I used the same front struts and welded everything correctly like pictured. In the thread there was about 3" left of the strut tube to sit one but I messaged him and was told to basically cut the tube clean off at the knuckle so the air strut would be basically sitting on the knuckle. I left about half of an inch but have seen others cut if off completely and work. The problem I'm ran into while testing is I'm basically getting no travel in the bag. Fully aired to almost max psi I would have very minor wheel gap but at driving psi, which is stated around 75 psi, I would not even be able to turn because of how low it sits. Everyone else seems to have plenty of movement building the same way. I tested it many different ways and the bag barely looks compressed when aired out. Without the wheel I can put the jack under the control arm and compress it quite a bit more which all I can gather from is that I should have left about 3 inches of the tube in order for it to work. But looking at other people's builds like mtlbloodshot, http://www.r3vlimited.com/board/show...r+ride&page=22, his is even slightly more cut than mine and is getting full travel. If anyone has any opinions or knowledge from doing this I would greatly appreciate it.

im familiar with the airlift setup everyone uses but ive never done one on an e30 myself so I cant give you measurements but I can say this, the 100%most important thing you need if for your airbag to be 100% compressed when your car is "laid out" so It sounds like you cut your struts down too much and now you have no lift.. are you positive you got the same struts as the guys who cut them as low as you? I believe there is a Long and Short version of that strut from airlift.. also another important thing is how tall is your wheel/tire overall compared to theirs? a smaller wheel will compress the strut less then say a 17" wheel.. theres a ton of variables and you really should measured everything before you just cut everything apart and copied someone elses setup

I have the same part numbers as everyone else. The shorter version is the 75564 and what I have and the others seem to run 75563 universal struts. That's all about I could think is that I cut them too low also but just seems strange that others have cut off even more than I have but get full lift. Thanks for the input.

Update. If anyone is actually willing to help..
I added 3 inches onto the strut tube on one side to make it longer and more compressed when airing out to compare to the other side to see if it would help resolve my issue and give more lift. But then measuring at all psi, both sides still stayed the same which is making no sense. Except near max psi where the longer side gained about in inch. Still confused and could use help.

I was on the 76654. Ride height was more lile 85-90 psi.

Nick, you're paying more for someone to do all of the work for you. Since they assemble the kit they will tack on an extra percentage for their time. All of those parts can't be bought separately for cheaper, but you lose the warranty from buying separately.
