Finding something short enough could be a problem.
Once you start into proper shocks with adjustment they should be able to re-valve them to suit the driving conditions of your car anyway. Increased oil capacity and gas charge are important with the extra load to help stop the oil heating up and foaming up which cause fading. Shocks have no load carrying ability, unless they are air shocks.
Interesting fact, the new style of forks on dirt bikes don't have a spring in them. They are carrying the weight on air pressure only.
As for socks, wool for sure. It's agroscopic to the point of saturation.
