Hey I had some Comptech springs installed a while back and after a little while I started hearing a clanking noise from the back of my car. Only at low speeds over bumps or when I come to a quick stop. I did a search and most people seem to think its from the end links. I just checked those today they all seem tight. On one side, the nut turns but when i put the allen key in there it won't budge, so I think that one's good to go too. The isolators are on the springs too so thats good to go. Could it be from the spring perches? Or should I try and lube up the factory sway bar bushings? I just don't know what to do right now...

Take it back to where you had the springs installed and have them check it out.
