There's at least one person here who's done air susp. on their car. Did you connect with him?

 

Unfortunately I did not....
I though to contact company first and see what they can offer.
Here's what exactly I'm looking to get.

 

What do you mean by you "did not"? He's still around AFAIK, so why not contact him now?

Here's the guy: The_Sauce

And pics of his ride: https://5series.net/forums/e61-touri...0/#post1539859

He was selling it last year, but then changed his mind IIRC: https://5series.net/forums/complete-...ension-135576/

Only problem I see with air bag type suspension is you can't change spring rate without changing ride height. I'm having that problem with the oem setup and KW's

 

@ Lotus99 - thanks for the links I'll check them up.

@ trackjunkie - yes, that's why I'm so picky about suspension upgrading.
I don't mind to put extra $1K to get full air suspension but it has to work good.
I digg Internet every night searching for any info, opinions etc. so far accuair has most interesting systems in my opinion. I read whole faq section on them website where they explain clearly the differences etc.
If my E61 gonna drive like this Audi I'm sold. Still waiting for email from them.
