So, theoretically (SP?) you should be able to run stock 1G AWD springs in rear, and 2 inch FWD or AWD DSM springs in front and the car would be level. What kind of issues did you run into in the rear before you fabbed the spacer bracket? Did you have to press the bushing out of the lower strut mount?
I am running stock 1g AWD springs in the rear, not cut at all. I cut the front springs one coil. If you were to run this setup without raising the struts up in the rear like I did, you would probably have to cut at least two coils off up front for the car to sit level. The issue I ran in to before making the spacer bracket was the spring perch rubbing against the inside of the tire, see the first pic I posted. I raised it up so that the spring perch would sit above the top of the tire (the way it should be.) If you're running smaller tires like 195's or 205's this probably won't be an issue for you, and can install the rear DSM struts as they are without making a spacer bracket. Since I'm running 225's in the rear, I was forced to do something about it.
Yes, you have to press the old bushing out of the Mirage strut and press it in to the DSM strut. There is no way around that. I was able to use all CSM stuff to make this work (i.e. CSM strut mounts front and rear) with no problems.
