About the only thing you could use on the doors is dynamat (or other
similar products like it) It's basicly a thin sheet of rubber or asphalt
based material (depends on the brand) with an adhesive backing.  The
stuffs quite heavy though, and you'd have to apply it to nearly every
surface inside the door for it to be effective, so your probably looking
at 8-10 lbs increase in door weight.  Personally I wouldn't recommend
it. I have no clue how it would effect torsion bar/strut performance and
life. I'm fairly sure a torsion bar adjustment would be needed
afterwards with any weight increase or decrease in the doors.

Another option I guess would be to stuff the doors with closed cell
foam. Don't use open cell because it will soak up water like a sponge.
The downside to this is you'd render your windows inoperable. My advice
would be to just leave the doors alone and soundproof the rest of the
car as well as you'd like. After all. it's the body that conducts the
majority of the road noise anyway, not the doors as they're fairly
isolated from the body by the door seals when closed.
