I would avoid the AC coils. Those of us with OEM Pro-4x coils already have issues with the struts topping out. (infamous clunk) Not sure about the AC coils on 5100s since I don't recall anyone running that setup.Yea, that seems about right. I don't imagine the previous owner would have gone through the trouble and expense of adding aftermarket UCAs if they didn't install a reasonably large spacer.
I guess I will look into other means of lifting the front suspension. I am probably going to go with the Bilstein 5100 series shocks with the adjustable ride height in the front. Do the rear 5100's also provide lift?
I also checked out these lift springs from Automotive Customizers:

Can the 2" to 2-1/2" lift springs be combined with the 5100's for a total lift of 4" to 5" up front, and if so can I still leave my spacers in?
If I can do this, I will probably match the rear with some blocks and add-a-leafs.
I just installed the wheel spacers off my old Xterra which give me about a 3" wider stance. I also ordered some Cragar wheels with a bit deeper offset. They have not come in yet.
