damn you guys got way off course here..anyways i have the same noise you speak of but its on both front coilovers and one rear. I know for a fact that my bump stops are worn out and just popped over the metal that holds them, thats what makes the noise on the front. Now for the rear im thinking i forgot to put one of the rubber gromets back in place which allows the strut to wiggle in place and rattle like hell. Just check out every ive said and let me know. If its not that i'll see what else i can dig up.

One other thing, i installed my WEAPON R COILOVERS(gasp) to raise my car as well. Im a broke ass guy trying to get around and look as good as i can..lol and im with you on the teins, i couldnt replace one if i blew it and id be screwed
