Eibach + AGX

OK I have my Eibach Pro springs (6028.140) and AGX (734019, 734020, 741020) ready to install but I need some advice from you guys. What stiffnes settings for AGX would you recommend to stay at around OEM level ? I don't want to go too hard because its my daily driver on really bad Chicago area roads. Set it to "1" sytiffnes level or go higher ? I won't do installation by myself so I have to set it up before going to mechanic to avoid removing back seat later. It will be installed on 2001 GTZ with stock 16" wheels.
