clunks at low speeds sometimes

I installed HR Super sports, took everything apart, torqued back to speck... still clunks sometimes..

I think that there is sufficient space between the spring and top plastic plate where the spring hits it, I will felt tape that area around so the spring sits tighter on it.
Thanks, report back once you finish!

If possible, can you take some pics of the underside of your strut tower like I did?

How much did the H&R's lower your car? Do you think the spring is coming unloaded at or near full droop?
