OK a couple of checks.Mine was doing this on speed humps when I first got it.The watts linkage hade been re-bushed,it had been put in upside down,one of the links was hitting the diff!!!!
Next,I get clunks and bangs since my polyairs went in.My spacers dont sit flat and refuse to do so,Ive levered them to where they are meant to be but they conform to the spring pitch,Im guessing there is a possible clung here.
Also after speaking with Ken,he inherited a clunk with a new suspension kit.Im wondering if the watts link bushes are worn to one position,when disturbed with new suspension,or polyairs in your case which equates some sort of lift,the clunk may be in there!!!!
