I forgot For anybody wanting to do this in their garage. It's completely doable but to do the rear springs (on cars with the active exhaust) we had to drop the exhaust to make room.
yea the way the exhaust routs there was no way to get the bolts out. We just took the hangers out and left it connected in the front and propped it up with some 2x4's
so until the springs have a little time to completely settle I won't have accurate numbers on how much drop was achieved, but right now I'm right about 1.25" in the front and 1.75" in the rear
