Any responses to this post would be of interest to me as well!

I just replaced the air suspension components for the front passenger side of my '04 E53 4.8is 7 months ago. Now it looks like my front driver's side components are in need of replacement.

I am seriously wondering whether I should spend another $1,500-$1,700 to stay Stock. Or, give up on the air suspension and go traditional spring suspension.

THANKS!!!
