I trimmed the rears as eibachs instructions stated. I have a coupe as well and sometimes I have to drive for lunch so that's where the back passengers come into play. Driving alone or with a passenger, the backs not bad, only when I have a full car.
I think I can wait til spring when i swap out my winter tires to readjust the rears. I'll do what others have done by cutting an access hole to remove the top shock nut so I don't have to remove all the trunk liners. The sheet metal plugs you can get at menards will cover up the holes and make for a clean mod.
I just adjusted the fronts this evening and will see if its better. Bump stops come Wednesday, got them and new dust covers for $29 shipped from fcpeuro.com
Keeping my fingers crossed and hope next weekends temps aren't too bad to swap them out.
