How do I know if I have air ride suspension?

look behind your rear wheels if you see springs then you don't if you see Black color air bag then you do. There is other ways but I found that to be the simplist.:dunno:

3.0i is usually steel spring, 4.4i, 4.6i, 4.8i is at least rear air. Since you have the 4.4i, you're going to have the air suspension in the rear.

Ok i figured out I have air suspension in the rear. So do I just need the front springs? I have been looking and if that is the case, why are the spring kits the same price. I have a friend that can lower the rear with the progman. Also has anyone heard of the Vogtland springs? How is the ride compared to H&R?

No, you need front springs and rear links that are either shorter than the OE links or are adjustable. Need to trick the self leveling system into lowering the rear to equal the amount of the front. The H&R system is a pair of front coils and a pair of adjustable rear links.

I don't believe the factory software can lower the car as much as is necessary, though I don't know that for sure. And be careful what springs you choose for the front if you have your friend lower the rear. Lowering the air bags in back only slightly stiffens the rear (accomplished by the fact that lowering the air bags adds a bit or overlap on the bags which will firm it up modestly). If you get a front spring that's too stiff compared with the rear, you will end up with an X5 that has a lot of understeer and will have twitchy steering response.

The adjustable links are a great option simply because they can always be adjusted. But yes the dealer equiptment cam change the ride height as well. It is an easy task as long as the tech knows what to do.

TowX thank for the info. Now I am a little cautious about using the the software to lower the X. Need to be sure of what springs and rear set up I am going to use. I have been looking at the VOGTLAND brand springs, all the specs look good. Also need to know how they compare to H&R.
