Hey Man, and Welcome...

The Torsion bar upgrades are actually just stiffer. (from what I understand)

The only safe way to achieve the lift you're after is: (IMO)

2" Drop Brackets for the CV
Reindex and Major Crank of Torsion Bars
2" Coil Spacer
OME912 Springs
Shocks of your choice (probably need longer, I'm not sure if stockers can extend that far)
Longer Brake lines
And some major trimming

Mine is probably lifted 3.5" over stock maybe a little more including tire height.

Search for the lift wiki, it contains links to drop bracket threads, as well as alot of info on different options for lifting.

Good Luck!
