Thought about the SAS, and may do it one day. But for now I would like to keep the IFS and see what you can get out of it. These mods sound good and they are already running 37's with it. Realistically I'll never go that big, even with an SAS. I like the idea if the ford 9" rear end with the 5.83 in it and then the matching 5.83 from calmini in the front with the IFS set up.
