Ok, so people with coilovers and drive their car's on streets, look into this option as it'll prolong the life of your coilovers.
clean off the exposed shock's threads from any road dust/nasty, and spray the threads with silicon spray or lithiume lube on the threads, and cover it up with bicycle tube to further prevent any road dirt/nasty from getting into them. Long lasting and non-rusted/seized coilover threads and collars, another happy coilover owner.
and as for the rubber on the bottom of the shock body, that's for people with PBM and Stance coilovers. the toe rod's nut/bolt will cut into the bottom shock body as they are big. that is to prevent further dmg made from the toe rod nut/bolt.
