I'm using BC coils with UAS bags and I run at about 85-90psi on the front and about 60-70 at the rear

I'm curious as well. Haven't installed mine yet but what's the soft side PSI?

OEM plus... your struts are probably set up to be too "short". twist the lower mount down and then you should be good to go. your rears might be set to be too "long" so you have super lift, but a crappy ride when lowered.

Cant go by PSI, its too inaccurate. You can lift up to "80" but if you drop from 120 down to 80, it will be at a total different height. Size of lines/valves has a lot to do with it as well. Smaller lines and valves tend to fill up the bag more efficiently than larger ones.

As for stiffness, using the same above numbers and fact, when you lift to that psi level, its nice and soft, but coming down from full lockup to the same psi, you're not only higher but much stiffer.

You can all argue this as much as you want, but its fact... if psi was accurate enough, they wouldnt have height sensors as well.

I always highly recommend a management system with height sensors as well. I'm not using them, but have a pressure management and only use that to give approximate numbers. After a while, you just get used to what the numbers actually mean. I end up using the 'feel' of the ride as my true height. I know when I'm knocking upper control arms on my fenders... I'm at the perfect height

and for those who are curious. If you want low and tight ride, lock the car up as high as you can go, flip a switch on the tank to get some more PSI and throw a little more air in, then slowly bring the height down and you now get a stiff and low ride


This is speaking for the UAS bag. Not sure if this would work the same way with other setups.

jokester... the ksport bags are a different animal, and the sleeve bags take over 100psi to get the front to even think about lifting.
