Dropped spindles lower the kinpins or balljoints in relation to the axle line. They are more desirable than an adjustable front beam because they maintain the factory amount of wheel travel and geometry. There are potential problems when dropped spindles are of the cut-and-welded variety, because the welding changes the tensile strength of the metal (its ability to bend and spring back to shape under stress without cracking). Cast reproductions can also have problems depending on the quality of the material and cast-work. VW were very good at this.
The third alternative (the one I believe Rob King uses on his lowered Type 2 spindles) is to swap the spindles right-for-left and mount them upside down which requires the tie-rod end holes to be reamed and tapered the opposite way, and a larger tie-rod end fitted to suit the larger hole. These have the advantage of using the factory cast units which I think may negate the need for any engineering certificates, but I'm no expert on the law.
I have no idea what they're worth, try checking the advertisements in Hot VWs or some other american VW magazine. 🙂
