Hello all, I am new to this thread, but I have recently installed coilovers on my 01 Civic. The right rear makes a knocking sound as I go over bumps. I am puzzled as to what might be causing this. I have taken a video of what it sounds like just me pushing the car down. Doesnt sound normal.

You can host this on youtube. I'm not downloading and opening files here. Sorry. A clunk could also be coming from the bushings/control arms. Were the coilovers used by someone else by chance? If new, I would probably rule those out if they are of high quality. Got a name brand for the coilovers you could share with us?
