here is my lowered crossfire with eibach springs and h&r spacers. (two friends have this set-up in my area)
i did add koni shocks 6 months later (personal preference but
not needed...i like a crisp rebound).
i have had this set up on my car for over 12k and no irregular tire wear at all. a normal alignment was completed a week after install. i love the look and near stock ride feel.
