And i think im safe in the rear cause my rear height is probably close to what you have in your pic right above this, but my front is lower.

The fronts use air struts....so they wont be subject to the same issues as the rear. HOWEVER, that doesn't mean you wont have other clearance issues....
I would be willing to bet you have rub marks on the top of the fender liner from bottoming out.
Here's an exercise for you: Air out the front, and put a chalk like on the tire where the bottom of the fender comes to rest. Now air it back up to your ride height. This is the maximum amount of compression travel you have before you smack the absolute minimum....you may be surprised at what you find.

After last night i'm just about a 1/4 inch lower then you in back but quite a bit lower in front. I will be removing the wheels tomorrow night to do the spacers and will inspect. When you switched to management what made you keep the rear bags and not switch to a UAS Aero sport or similar aftermarket performance bag?

Essentially with aftermarket universal bags, whether they're rolling lobe, single, double or even triple convoluted designs.....have to many unknowns. What do I mean by that? Well for starters, there's the ride that they produce, which is dependent on things like material, # of ply's, suspension geometry and the pressure range they are designed to operate in. Secondly is the mounting issue---you need to find a bag with the right dimensions for the range of heights the X operates in but also contains the proper mounting points. Things get even more tricky when you move to the struts up front, as your options are even more limited.
When I was planning my system out, I only intended to go about an inch lower than the factory ride height of a 4.8is----just enough to even out the wheel gap for daily driving. I have the ability to lay it right out like you see in my sig, but it isn't drivable like that----strictly a photoshoot/parking height.
I looked into many (and probably just about all) air suspension "kits" that were available for the X. The airrunner kit was what I wanted to go with, but they wanted $4100 for just the struts and bags, and also would not warranty them if something went wrong with them because I wasn't buying their "complete" setup (I already had my valves, controller and compressor by that point). I would group universal air in with the stuff from
airbagit.com and the lot....not exacltly quality stuff. If you want to do a true "performance upgrade" either go with the airrunner kit or contact the guys over at ride tech and have them fab up a set of Shockwave select's.
So I suppose to answer your question as to why I chose to stick with the BMW bags and struts....because it would do what I wanted, give me a ride I was familiar with, keep the install relatively simple.....and all the while being relatively reasonable in price (for a student lol).
Just one last point before I sign off here....
Guys, I don't mean to harangue you about this kind of stuff, but things like checking clearances after you play with the suspension is one of the first things you should be doing....just looking at the pictures that have been posted, shows that there is a ton of oversight/inexperience on your behalf. When things start to break (and they will if you keep driving around smacking bump stops all day)....don't be surprised if you receive more than a few "I told you so's". Please, if you don't know....ask! That's what we're here for!
