thanks, most of the online vendors cant seem to answer my question. Im trying to retain the rear air springs.

So how did you lower via software

Then save the money and just get the front set.

funny thing is there is very little (none) price difference on the ISC fronts only...

Yeah, I can see that. I would get the complete set in case something goes wrong with your air compressor or bags (in the future).

Are the rear shocks separate or are they built together with the rear coil over spring?

If anything I would like to change the rear shocks with the new one

They are all separate. Air bags and shocks are separate, ISC sends you shocks and springs that are installed separate as well. So, you could do as I did, I replaced the shocks with theirs (which are dampening adjustable) and kept the air bags.

my thoughts exactly

I too am interested in front only coil overs. How is the ride comfort compared to stock?

pocholin

Very different, much tighter. The first setup I had was street sport and I don't quite like the fact that there's very little travel (spring) on large road humps, which means the car returns very quickly to its standard position. I prefer a little more "boaty" ride, so I ordered longer shafts with longer springs to retrofit it into a street comfort. Ride over small road imperfections is very good at either dampening setting, no complaints on that side. On large bumps (like ugly train tacks) I bottom out with current setting, on longer shafts I should bottom out even less.

I guess a younger crowd would prefer the street sport setting, people like me (past mid-40s) would probably prefer a little more comfort.
