I just went thru all of this. My 1123 was MAK'd and still had the 3k springs on it. I just replaced the rear springs with variable rate (did the cast uppers, the front lower bolt is not even close to being fun to remove). I did the front springs with the 954lb and disconnected the sway bar. It is a whole different vehicle. I used to have a hard time doing 10mph on my gravel driveway, now I can do 25+ without getting bounced out of the seat. One of the trails I drive weekly used to be 10mph tops before I would get tossed so hard the seatbelt would stop me from flying out of the seat. I drove it multiple times yesterday at 10, then 20 then 30mph and it was great! I now have the vehicle I thought I was buying!

For driving around town, the MAK springs rode great....but I bought this to offroad and the MAKs were TERRIBLE!
I posted in July about disconnecting my shock absorbers to see if they were the culprit in the rough ride. After changing only the springs, I can definitively say it was the springs.
