I would try adjustable spring hangers... you can get them for the front or rear. I've got AREngineering front hangers, and with the spring in the upper position, it lowered the rear by about an inch at the wheel well. The rear shackles I have are also adjustable, made by Prothane, but I'm not using them in the lowered position. To me, it eyeballs like there isn't enough travel and might bind the spring, but I have NOT tried this to verify. I was a little disappointed also that the "stock" setting is a tad HIGHER than the shackles I removed, so I didn't get as much drop out of the front hangers as I might have otherwise. AREngineering and DoctorDiff both make adjustable front hangers, and DoctorDiff's also have about 1/2" offset to them, too. You'll have to relocate your spring perches if you go that way, though.
