Are we going for a looks base lowering or more performance? What wheel size, 20x9 or 22x9?
I have a modified Belltech 2/4 that is really somewhere between a 3/4 and 4/6 ish... I don't really know. But if I were to do it over again, I would do a combo of both McGaughys spindle drop and spring drop with either a Crown 1" spring or cut stock spring up front . And a a cut spring of choice, both McGaughy and BT are about the same in the back...
After that depending on how low you go, a set of spohn arms and panhard to correct the rear axle alignment should also be in the works.
But for closest to stock component angles up front I would go with the McGaughys 2/4 spindle drop and go from there lower
