My struts are going bad, and I want to get SS/TC shocks/struts, can I put eibach or h&r springs from a S/C or are the turbo lowering springs different?

 

You can use any lowering spring in with any strut set up, the springs that say they are for the different models only change how much they lower the car. I would suggest either going with pedders or ssc/cm springs

 

yup
