Clunking noise in the back!!

I recently have installed BMR's 1" drop spring kit in my 2010 SS and have barely even driven 200 miles and I have already started getting this clunk noise from the rear. If I was to drive over a speed hump normally and straight, I won't hear anything, however if I was to drive over the hump at an angle forcing each wheel to individually go over the hump, then I hear the clunking noise come from the rear corners of the car...but only inside the car. As in if my only my rear right wheel is going over the hump (or any obstacle), I will hear a clunk noise from the rear right corner of the cabin of the vehicle and if it was the left wheel that was going over the hump, I hear the same noise in the rear left corner of the cabin of the car. I have asked a friend to stand out and keep an ear out for any noise, and whilst I could hear the noise clearly inside the car...nothing can be heard outside. On the other hand, if both rear wheels were to go over the hump (or any obstacle) at the same time, no sound can be heard inside nor outside the car. Any idea what could possibly be wrong?

Were your bushings timed? Its essential that the bushings be timed so that the ride quality won't suffer

Couple things that come to mind right away:

Did you get an alignment after the install? If not, go get one!!

Did your springs come with insolators? If so, make sure they are positioned properly. If not, that sucks!

Is everything TIGHT with loc-tite?

And already mentioned, did you time your bushings after the install and BEFORE your alaignment??

That's what I'd check first.

They said they timed the bushings when they alingned it but i'm sure they didnt cause the ride is squishy. Ill bet they didnt do my rear upper control arm bushings.

I experienced a similar issue and after a full disassembly and inspection that revealed nothing I went to coil-over and never had a problem again.

Same thing I said. The black plastic that comes around the spring coil. Make sure that is still there and didn't get thrown in the trash.

swaybar endlink had to be disconnected from the strut/shock during the install and is a common source of noise- make sure they got re-torqued to spec. stock endlink nut is 36lb/ft.

Did that come on the stock springs?

In the rear the spring loops can rest on top of each other. You can put plastic sleeves on the spring to help prevent noise when the spring expands and compresses. Not sure what their called. Coil isolators maybe.

Can you post a picture, similar to this one, but show the coil from the shock bottom up?

I rotated the rear springs 180 degrees and the clunking went away.

Seriously?

They were installed incorectly then. They are supposed to be butted up to the groove like in the pic I posted earlier in this thread.

That'll certainly do it.

It seems to be a problem with the retainers that come with the DSE springs. By rotating the spring it provided more relief between the retainer and the coil beneath it. I am going to call them tomorrow to see why this doesn't seem right. It seems the retainer hangs too low.
