Yeah I tried installing the eibach prokit on my car today. The front shocks went in alright, but the rear was a *****. I can't take off the bolt on my rear shocks. They designed it really dumb. They have this bushing that prevents the bolt from coming out. I tried using a 1000 psi torque wrench to take it off, but it was a no go. Has anyone else have this problem when they tried installing their springs? Or does anyone know how to take it off?
