Eibach does not make shocks (at least not last time I checked). Bilstein makes some good quality shocks unfortunatly I think everything they make that fits the SLK will be a step down from the stock AMG shocks. You can't go wrong with the Koni's. You can also check and see if GroundControl makes shocks that fit the SLK. They are very nice shocks if you don't go too low.
