Air Suspension Thread

This is NOT A BASHING THREAD!!!! This thread is being created to help all those who are wanting to use air bags as a suspension option for THEIR vehicle. If you are not in here to help please keep comments to yourself. So please feel free to ask questions as needed. I'm not an expert when it comes to bags but I have enough knowledge to help.
So if we can lets try to follow this format when posting your suspension:

Brand/Coil type (if applicable): K-Sport Kontrol Pro Coilovers
Air Management system: AccuAir Stage 2
Bag type (if applicable): UAS Bag over coils (front) / Air House 1 bags (rear)
Air Gauges (if applicable): Zaetech DigiGauge
Any additional suspension mods (endlinks, sway bars, camber plates, etc): none
Any pics you have: I'll upload more pics of the install later once I make it home.

Question, air suspension still uses a traditional shock absorber, but just have the airbags acting as the alloy spring found in most cars. I know these system are bulky and can be unreliable, but from a pure performance standpoint, a correct setup should perform just as well as an equivalent alloy system, correct???

This is true...with the correct set up it should perform just as well if not better. It does take some playing with strut/shock adjusting/dampening/rebound etc.... In the near future I'm upgrading all my suspension to M3, and up grading coilovers...Probably to either BC Racing or KW2...I know they are two different ends of the spectrum...but ....yeah...oh well lol

A properly setup air suspension system can perform VERY well. We just took KW V3s off of a car and put a Bag Riders kit on it and the customer insists that the handling is superior now.

Weight wise, the car is lighter in per corner buy ~2lbs but has a 14lb control system in the trunk. (Just as a point of reference). He went with an e-Level so the car is calibrated to maintain his aligned height at all time, even with four people in it.

I'll be joining the air side soon. I purchased a system from another 1addicts member. There aren't any stance/air threads over there so I'll troll over here in e90post lol

Brand/Bag type : Bagriders front struts, Airforce rear sleeve bags, Koni adjustable struts
Air Management system: AirLift v2 with 5gal (raw, will probably be wrapped)tank and Air Zenith OB2 compressor
Air Gauges : AirLift v2 (Digital Guage included)
Any additional suspension mods : Megan Racing rear camber arms

Will try to get pictures of install and will definitely have pictures of trunk setup once finished.

hey guys im about to pull the trigger on a bagriders kit, but i have a questions about the rears. If i don't go with the air lift performance rears and opt for the cheaper koni shocks & UAS rear I'm going to need camber arms to adjust camber in the rear, correct?

Let me say first, that I know who you are, and that your builds are mind blowing.

Now, let me ask: how do bags perform better than coils? That just seems counterintuitive.

That depends do you need to get past -3 which is roughly the max that stock adjustment can get you.

Oh and my air suspension install starts next wednesday. It wasn't so soon after all. I waited 4 months with no real reasons and vague answers from HP Drivetech.

not sure if you guys could give me some insight. I currently have a 2007 bmw 335i with BC BR coilovers. I want to get air bag suspension but don't want to spend a fortune. Im not going to do any trackdays so i dont need super stiff stuff. Just wondering can i just use my existing front and rear struts and replace the springs with air bags. if so can you link me to some suitable bags? there are so many and i dont know which would fit.

many thanks

These guys are probably the best company to deal with and give you your best choices. They know what you need. http://www.bagriders.com/modlab/. Also yes you can use your Bc coils with bags. Just like ACEE has.

You should be good. Besides what we talked about, you shouldn't have a problem.

You can hit up bagrider.com (fishmando) on here. They are EXTREMELY helpful. I like yourself didn't want to spend more money on new suspension.
as for front you can do the UAS Bag over coil options (which is what I opted for):
http://www.universalairsuspension.co...rsal-p-38.html

and for the rear you have two options:
the UAS rear (which i got b/c at the time it was the ONLY option available)
: http://bagriders.com/modlab/products...-REAR-KIT.html

or the Air lift:
http://bagriders.com/modlab/products...-REAR-KIT.html


hope this helps you out. I personally like the Airlift rear design better, but I'm not needing to spend more money to change out what is not broken.....
