It's most noticeable at speeds below 15. Although I can hear it a little at faster speeds.

I had almost exactly the same problem... Mine turned out to be the coil insulators not installed....

But you've got that one sorted... how about the rear swaybar D bush straps... if those aren't tight you could get the same noise.
Did your's come with the taller bushes?

Good idea to double check the strap bolts.

If you can find a safe spot in a parking lot do you have a trunk monkey available?

You are making me rethink which bushings I put in. I was sent both types for the rear(long story). The ones I put in fit pretty good. Here are the ones not installed. They are thicker up top compared to the ones on the car. Name:  ImageUploadedByTapatalk1375152071.618016.jpg

You have a ten so the smaller bush is the correct fit.

The exhaust looks to be clear of everything. I may just wind up ripping out the whole rear and reinstall. If that doesn't work time for the pro's at ADM to look at it.

LOL....that's assuming he didn't change out the straps for some reason like I did. I found out the hard way that FE4 straps are 1/8" smaller than FE3 straps. So, Pedders has two different bushings for the ZL1 bar depending if you have FE3 or FE4 straps.

Ace....are the rear sway bar straps you have the OEM ones that came with your car?

I'll say that I never heard any noise when I had installed the wrong bushings. The say bar just was moving inside the straps when it shouldn't have.

Would it be possible at all to maybe try to get some video of it?

Has to be the strap and the wrong bush. Take a pic of the strap around the bar from a side. The FE4 straps are actually taller than FE3, I had both.

Correct, I had it backwards. In my case I told Pete I had FE3 (which I thought I had) but in reality I had replaced my original straps and they ended up being FE4. Because of that my sway bar ended up moving inside the staps fairly easy. After working with Pete we determined there was an 1/8" difference and that I had the FE4 straps. Pete took care of me and now I'm all fixed up now.

Like I was saying though, I never heard any noise and I probably had the wrong bushings for 2 - 3 months.

I'm not saying that's not the issue and Ace should double check just to rule it out but I'm just thinking that's not the cause of a metal clunking sound.

Fe3 straps with the "tall" bush. They fit like OEM. I'll try to grab a video but it will be hard by myself.

Forgive the sub in the frame. I was working on a wiring issue today that has nothing to do with the sound of the suspension.

There is something definitely loose. I would check all of your bolts again, INCLUDING the 4 upper bolts that hold the coilover to the body..

Also, check and see if your adjuster for the coilover is hitting against the car. My right adjuster flops around and actually hits on something occasionally.

One other thing to check, if you haven't relocated your E-brake cable, it might be hitting on your rim now that you lowered the car. Mine hit on both wheels when I installed the 1LE/ZL1 wheels.

The more I think about it, the more I think it is going to be your emergency brake lline hitting against the wheels and the wheel weights, or the adjuster, but man that sound sure sounds like metal to metal clunking like something is loose.

Do you have a tire stem style TMPS?

How much does your stereo weigh?

Oem style tpms. The sub, amp, and box are less than 50lbs. I'm truly stumped. I had my torque sheet out and did every bolt/nut to spec with Loctite. I'm going to tear out the rear end and reinstall from scratch when I get back from work Monday. Going to loose some more hair over this one.

1st, put your floor jack under the diff and raise until the wheels are off the ground. Check the rear coils. Are they tight or have they become loose? If the coil or coils are loose when lifted, the OEM rubber strut mount bush has pushed through the upper strut plate. This will make a lot of clatter. Generally it occurs when a top or bottom washer to the upper mount plate has gone awol. The fix is to press it back it and reinstall with the top and bottom washer.

I hate it when parts decide they would rather be on the floor or bench or rattling around in the trunk.

2nd, Chevrolet made a change to the rear strut upper areas creating a dome like space. They did this because the washers and top strut not would occasionally make noise under contact. We have seen this on a few cars. The fix is to take an air hammer with a nylon bit and create a dome by banging away. This occasionally happens to the OE configuration and occasionally with a Pedders install. You my need a bump in thr trunk.

Finally did you have a friend helping you with a dark sense of humor? Check for steel marbles. Before you say that would never happen, I should admit... the weather in Indy looks great for this weekend.

It feels like the install demon threw some metal bearings everywhere. Haha. I'll check out the struts today. Are there any pictures of what the domed and in domed strut space look like? I have a late 2010. #116xxx. Now I'm really wishing I could make it up to the fest.

I've seen them on a 2013 Camaro. They might have started it in 2012. If you don't know of anyone with a '12 or '13 then post a request on the forum for someone to go out and take a pic of their trunk with the carpet pulled back. Compare that to your trunk and you'll see the domes.

Hang it there....you'll get it sorted out. I just went through something kind of similar but it was with the front steering on my car. After a couple months, 2 trips to the alignment shop, and a few phone calls with Pete we finally got it all worked out. Mine issue ended up being the wrong bushings for the rear sway bar because I had changed straps and also (the biggest issue) my steering rack had come loose. That made for some fun cornering. It bugged me daily and I had started to think about my option of pulling my parts off and trading it in for a 1LE.
