I've been reading and found out that the Tein CS shock/strut body is made of aluminum....unlike the "normal" Tein coilvers (HA, HR, RA, etc) which are steel....so does this mean there shouldn't be any problems with rusting on the threaded sections (which I assume is aluminum) on the CS's? That was another concern for me since I know the FLEX's have teflon coated threads...and I live in Ohio...where they use salt like no other.
