I keep reading different things are needed. I plan on doing the Steeda Sport because I want a mild drop. I chose it over the P springs because I want the backend to settle down a little bit for a more level look. I know I will need a panhard bar to re-center the rearend. What else is a must? I read I need new FRPP GT500 strut tower mounts? New struts? I heard the rubber bump stops need to be replaced? Not sure what all is a must on a mild drop?
