I have 2 bagged Subarus and went through Bag Riders (they are out of Vermont by the way, not Cali)... but at least on their Subaru setups they used a lot of BC Racing coilover components on their performance series air struts. I am not positive if the same goes for their BMW setups, but its worth looking into since I know BC Racing makes a coilover setup for the X-drive, they just take an additional 2 weeks to build. You might be able to work with Bag Riders and BC to come up with a set based on the BC BR series X-drive hardware and have Bag Riders fabricate the X-drive coilovers with some air bellows. Ask for John Hall or Will Fisher at Bag Riders, Will is a BMW guy and he can probably work with you to come up with something. Those guys know everything there is and can hopefully give you some more insight. Not trying to get your hopes up, but if at all possible, they would definitely be the ones to make it happen.
