Strange Noise...

I'm lowered 1.5'' on 16'' rims with tokiko blues springs and struts. Whenever I slow down for a stop, I hear a faint, but definitely noticeable "clicking" noise coming from the rear right wheel area.
What could that sound possibly be? I'd appreciate any help. Thanks.

Now i'm curious. Because i've exactly the same noise after lowering my car. Also from the right behind. My guess was that it was the combination of stock shocks with lowered springs. I guess on a certain moment the spring has less tension and can move a little. But i have to admit that it's a huge guess.
I surely can eliminate a bushing problem, because they were all replaced. And if the car stands still i can force it to make the same sound.

honestly i have had a faint clicking noise since i bought my HB brand new.. before lowering it.....LOL i especially hear it when i go through a drive through and you hear the sound alot better.... not sure what it is... good luck.
