Clunk coming from rear passenger side

[gt5.0coyote]

Hey guys I'm having a issue that is getting worse. When I hit a bump on the right passenger side you can hear a loud clunk. Does anyone have this issue? Its been lowered 1" in the rear with frpp and also has frpp shocks and lower control arms. Upper is stock. Any help is good.
Thanks

My 2012 GT has a clunk in a similar spot. After crawling under the car and doing a little searching I found that the bushings for the sway bar are trashed. Each time I hit a bump it knocks around, I can also hit the sway bar with my fist and it makes the noise - just not as loud. I didn't see in your signature that you had changed out sway bars, mine are currently stock.

Rock auto has the links very cheap. The OEM and service ones are all of the revised design for 2013 MY with way more rubber preload. hence the don't wear, they could make noise in the cold from all that preload but if you use a Teflon / silicone grease all over them it should be good for life.
