Plan A, cheapest. Remove 2nd and 4th spring leaves front and back. That should get you almost an inch at each end, and not adversely affect the ride and handling too much. You may occasionally hit the axle snubber.
Any greater lowering gets you into dropped axles, which is an expensive and challenging undertaking for the DIY home mechanic.
Plan B, maybe $400. Replace front and back springs with new reversed eye main leaf springs. That will drop the car about an inch and a half. You may still hit the snubbers, but the front spring shackle angle should be preserved near 45 degrees, which is important for anti-sway handling.
The empty-car stance should be raked a little nose down to allow for rear passenger and trunk loads. And most think a little rake looks better.
