Then I guess bags is probably the way to go - just understand that each time you change the height of the ride, you really should get an alignment. Changing ride height alters your camber and toe. It sounds to me like you are trying to find a suspension that lets you do everything. Nothing wrong with that, it will just require more effort on your part - meaning, if you want to do an autocross, you probably won't do it slammed, as you will want some "suspension" travel. So if you are daily-ing it slammed, you will need to raise it up a bit and get an alignment. If you have a different right height for drag, you will want an alignment. In addition to this, the alignments for corner-carvers and for drag cars and sort of opposites of each other. Corners like slight toe out. Drags, I suspect, like a touch toe in. You will get adjustability, but unless you are willing to spend time making adjustments each time, your car will never really be "great" at any of them. You can run a 0 toe for example, but it won't be ideal for the corners, and won't be ideal for strip. If you are okay with these compromises, then all is good. Your setup will not be a set-it-and-forget-it setup.
Not criticizing, I don't blame you for wanting something that lets do you all 3 things (drag, track and street). Just know that it's hard enough to get something good for drag/street, and good for track/street, it will be quite difficult to get something good at drag/track/street without changing a bunch of things each time. Tires are another example. Track tires and drag tires are quite different and accomplish different things. Drag tires suck on corners, and vice-versa.
Just FYI, I'm not trying to talk you out of anything.
