I think I may throw a water trap post tank/pre manifold and get a new check valve. Also, this is a weird question. My V2 is set to air on ignition, so when it airs, even if the tank isn't at the low threshold for fill the compressor turns on and fills the tank. I have it set to 125low/175high. When I start the car and it airs up it will automatically kick on the compressor. No matter the pressure, as long as its not above 175...is that normal?

I've got a bit of a clunking problem with my AirLift set-up
What's strange is the noise, it only occurs when one side hits a bump VS both sides at the same thing (leading to believe sway bar, its been checked) The noise I get sounds like the bag is beimg turned inside out, its got a sucky-thunk sort of sound, rather than the more solid metallic clunk of a standard coil over.. Any thoughts at all? I know that's not a lot to go on.. I'm hopimg experience wins over here.. hahaha |

Had this problem too. I think what's happening is they are bottoming out when going over bumps. The solution for me was to run the rears about 10-25 psi lower than the fronts. I don't know why airlift says to run the rears higher if this problem happens to everyone. I also run my dampers on full stiff for now.

Mine seems to be worse after sitting as well but its hard for me to say.. I dont DD the car.. Again though it "sometimes" happens over straight line bumps but they have to be pretty bad, on single sided or around turms where the bumps are offset is where Its really noticeable |

I have a question about the rears.
Is there a longer lower mount, so we can raise the rear up, even at ~60psi I am tucking wheel. I'd like it to be a bit higher at drive height in the rear... |

I've heard this from a few GR folks, so we took things into our own hands to develop a solution! Air Lift designed the rear shocks for extreme slammage, seemingly on stock wheels.... but I don't think anyone wants to be tucking a stock wheel at drive height We are working on a potential solution that should be out of production in a couple weeks. Things have been crazy here with our SEMA project, but that shipped out today so we can focus on other projects that were temporarily sidelined, like a longer GR lower mount I will keep you posted with our progress!

Well freaking let me know, I'll test em out for ya
Especially with winter, a tad bit of ground clearance would be nice. |

Do you drive on 90psi?
That can't be enjoyable at all. |

I drive with the fronts at 44psi and the rears at about 90psi. It's actually not bad at all, the only part I don't like is the noise. They were bad at first but I softened the dampening.

Hey Aaron. I thought you were on Universal struts? I can't find you in our customer management software anywhere, but that could definitely be our bad... do you have Performance Series (threaded body) suspension? The lower mounts we provide for our Legacy kits are about three times as long as the GR lower mount, which has been received quite well by our Legacy customers.

Hi, sorry I should have clarified yes I am running the universal struts. When I was doing air ride was no official kit for the Legacy. Originally I had the 5inch struts in the rear but it didn't go low so I got the 4 inch struts. Unfortunately I sinned and did not purchase from Bag Riders . But your help has been greatly appreciated and when I do switch to e-level I will be calling you. Regards, Aaron |

I'm bringing this over to talk about clunking. I personally only have a sway bar endlink make a popping noise when I raise and lower and only sometime. That's literally the ONLY noise my suspension makes. It's quite incredible actually. The GRs definitely need a shock redesign, our stroke sucks in back. |

As you fill the spring with more pressure, the shocks piston is also moving closer to the limit of its vertical travel. If you drive around with the piston at, or close to the limit of its travel (either top or bottom) it is likely that it will max out one way or the other when going over a bump, and therefore you get that horrible sounding "thunk" noise. For this reason, when designing your air suspension, you want to be as close to the middle of the shocks travel at your drive height as possible. Of course, the less shock travel you have to work with, the more difficult this is to obtain. If you only have 3" of travel, operating at mid-stroke means you will have 1.5" of drop and 1.5" of lift from your drive height. If that isn't viable, then you have to sacrifice travel one way or the other, which is a personal decision you have to make. This phenomena cannot be blamed on Air Lift, or air suspension at all. Subaru's rear suspension design of the Legacy (and newer Impreza / WRX / STi) makes it next to impossible to get low without sacrificing travel, since the OE shock is already very short. Fortunately, it isn't often that the rear end is what prevents you from getting over a speed bump, so even with a measly 2.5-3.0" of travel (Air Lift shocks), ideal ride comfort and mobility can still be obtained! I hope this helps! Let me know if you have any other questions! |

The sway bar end-link making a noise when raising/lowering is something that I wouldn't associate with air ride components, it is more so with the change in suspension geometry. Do you have stock end links, or aftermarket? I have Kartboy endlinks and a Whiteline 24mm RSB on the stiffest setting. Sometimes I get some creaking but that's about it. I would check out your bushings. Did you loosen everything during the installation, then re-tighten at your drive height to allow suspension components to "re-settle" at the lower height? This can make a very big difference, despite it seeming like a relatively minor procedure! |

I have whiteline endlinks and a stock bar in front. It was loosened and tightened at drive height. But when the car airs out the geometry changes. Things move, it doesn't bother me at all. Just the only thing I've noticed. |

I should pull my endlinks and back out of the garage, there's like 3-4 bumps in my long driveway that cause the clunking right off the bat... Mine seems to be the worst on the passenger rear, with complaints coming from the drivers rear once-in-a-while... |

The clunking should be tested, however. Does this happen with all pressure? I would guess you either have too much pressure in the bag, or your dampers may be set too stiff. Air Lift recommends not using the "full stiff" setting, rather backing off a few clicks is good. |
