Icon UCAs- how little lift possible?

Alright guys, dumb question and I'm probably over thinking this. But with my spindles and Icon C/Os up front I'm sick of my bro lean. I do not have the C/Os dialed all the way down because I had some concerns about the Icon Tubular UCAs. My thinking is, since they are longer than stock, if I get rid of the preload on my shocks, I will not be able to get it aligned properly. Anyone think differently? Or how much preload can I leave on the shocks and still get proper alignment? I'm thinking decreasing the preload and combining with the Dakars with their aal (I currently have stock leafs with a pro comp 2" aal and Icon resi shocks), I can finally have a level truck again. Thoughts?

 

Thanks Chris. Appreciate the help. So now once I get the new leafs, guess I'll just sit and play with the amount of preload.
