What are the attributed of the coilover type suspensions that are appealing to you? Adjustability? Bigger selection of brake kits? Rack and pinion? Weight reduction?

I've got King Coilovers on the front of my YJ and they are amazing. Click it up on the dampening and I don't even need sway bars, drop it all the way down and I'm super compliant on the trails, plus the spring selection is outstanding. Granted, I really don't need that on this build.
