Bruce,
If you have IRS check out my earlier post. A book with useful info on this subject 'How To Modify Volkswagen Beetle' James Hale. It is a job that you need to have 4 or so hours to do.
I used a strut spring compressor (a piece of all-thread that has a hook welded to one end and a sliding hook that is forced up the thread by a nut), this was to load and unload the spring plate.
A protractor with a magnetic base, found at the local home/hardware store. Used to match the angle of the unloaded plate.
A 10 point bit to remove the axle from the bearing housing.
Various sockets and wrenches.
For IRS with long torsion bars, a 2 1/8" hole saw to allow the spring plates to be removed. (And no for me; the place where the simulated torsion bar covers on the fender did not line up with where I needed to place the hole.) I did not try to raise the body, and I found 356klasse had torsion bar covers.
If you want easy adjustability and do not want to be commited to a set adj. There is that option which I have no experience with.
If you have IRS with stock Torsion bars and want to go 2", have I gat a deal for you, or any one else that this would fit for. Email me .
You can try just moving your stock spring plate down one spline which will drop the rear end 2". I did this, liked the look but not the ride.
