Pfadt Suspension - Weird Sounds??

I recently installed the Pfadt lowering springs and sway bars with end links on my 2010 camaro ss. When I drive my car I am hearing this sound that is difficult to describe..

The sound usually only occurs when I am driving slowly or going over a fairly bumpy road. The sound is not loud but it is definitely noticeable.. It is almost like the sound of horse hooves but on a softer level. It's like a crunchy/bumpy sort of sound that sounds like something is being shaken or moved around. Is this normal? Has anyone experienced anything this

Not normal. Most likely cause of the soft thunking or popping noises is the endlinks are not tightened. Also double check the orientation of the rear endlinks. More info here:

Yep, TCao is correct. Check that thread out. We must stress that torque values are important. Be sure to do endlinks at 33lb/ft. and sway bar bushings at 22lb/ft. and check orientation as noted in the thread above.

Give us a call if you have any more questions!

Crap, I have some weird sounds as well.
I brought it back to the car care center and had them check that very thing was ok, and tight. They kept it for the day, and told me it was ok, they even re tweaked the alignment after I drove it for 2 weeks.
It sounds like a clunking sound, I don't like it.
I will have to question them on the end links. I am no mechanic, but is it something I can see for myself?
