I put my tocs and springs in the rear. When i hit bumps i hear this knock sound. I thought something was hitting my trunk from underneath. Anyways i check it out and found out that one of those bell looking things by the sway bar is closer to the trunk then the other. Since i am dropped i think that bell thing hits my trunk. That noise just pisses me off even on little bumps i get it. Any ideas guys? how to stop it.
