I thought the coils needed to set in. After that, nothing for more than a month. Then I had 2 adults in the car, one in the front, one in the back and heard the same sounds again a few times. I checked under the car and couldn't see anything bad, no rubbing, no scratching. I don't see how the sway bar could hit anything, since mine (Ultra Racing) is installed right under the axle...
I believe the clunking comes from the fact that my Progress coils are different than the stock ones, the first 3 spirals sit on top of each other so there is more contact between the coils thus, more potential for clunking noise...

I'll say put it back to the original position (lower pivot point and then problem solved) I put it back on mine and it "comfort' level is back & there is no longer any strange sound fro the rear.
