Yes, it has shock mounts on the lower control arms.
You can let the springs sit in the perch, but yah, DLF's hats are a better idea.
You may not need to use the lowering springs if you use his short hat or don't use a hat at all - seems like factory springs sitting in the perch are a 1.5" drop or so, but search and see what DLF says in his sales lit for his top hat.
He's also got better bushings to mount the subframe to the body.
I presume you're doing this to reduce the weight back there?
