4*... I'm not sure what my caster was before I installed them, but I put an OME lift on back in October and never brought it to an alignment shop for some dumb reason. Lift is a standard 2.5 - 3 inch. I knew I needed shims. I swear I could see the caster was negative when I looked at the front wheel in the wheel well. Now, I just need to have a shop fine tune the TRE if need be. My steering wheel has always been off too, so maybe I'll try to mess with that next weekend. Slowly attacking my steering and handling issues...
