Put your bug up on jack stands, remove the rear wheels, remove the lower shock bolts. Let the suspension sag all the way down. Remove the bolts that hold the spring plate to the trailing arm. Your spring plate will be on a lower stop, remove the torsion bar outer caps, I remove the fenders too, I doubt they will come off with the fender on, but I have never tried. Use a large screwdriver or prybar to pop the spring plate out and over the lower stop. Be careful, the spring plate may pop down hard so don't get in the way of it. The pressure is now off the spring plate and you can remove it from the torsion bar, sometimes they are sticky and difficult to get off.

Are coil springs an advantage on a street car? That is a personal opinion, performance wise- I doubt it. They are easier to adjust the ride height and springs can be easily changed to get your prefered stiffness and they look really cool.

Your torsion bars/spring plates/trailing arms will bolt on to the bug torsion housing, no need to swap housings. You will need wider fenders to go with all the 944 parts.
