Those shocks are junk, you would be better off spending the extra money to have a set of Bilstein's shipped to you or get a set from the dealer.

Their is no way for us to know what you have as Inted said W140's used many different suspension set ups. You should talk to a MB dealer, with your vin they should be able to find what you have.

ADS is probably more then just shocks to addapt ADS you would probably need a few computers inside the car and then have to figure out how to intergrate everything so it works.
