Thanks for the suggestion Doug; the car came equipped with Ferodo HP1000 pads which are classified as "street/light track". I'm not married to Ferodo and I threw out the EBC suggestion as I've heard this addressed some noise issues for the Camaro folk.
I believe I've correctly bedded in the pads, I even have a youtube video of me doing some of the stops!
My original post was intended for SLC owners who have the Brembo brake setup (as supplied with the base kits). I'm sure I'm not the only one with squeaky brakes so I was wondering if anyone had decked this issue on their car, and what they did to do so.
This setup is known to be noisy on the Camaros as well; GM implemented dampers on the pads but later eliminated them (PaulW's post) - I believe because they found the dampers did little to address the noise issue.
That said, I did something a bit screw ball and it may have addressed the issue on my car. The stock pads have a rubber coated shim affixed to the back of each plate. A silver metallic plate is then used as a shim between it, and the pistons. My car came with only 1 set of these metallic plates and it doesn't seem like having them in place makes any difference. I acquired another set of the rubber coated shims and stuffed them in between the pistons and coated shims already affixed to the pads. Prior, I had scraped off any remaining bits of the "Disc quiet" goop that I'd tried earlier - so everything's free to move around more.
With the new setup I've logged ~200 miles of freeway/city and the brakes are only making noise occasionally, and at a reduced frequency and volume than before. I can easily live with today's current state.
So - for anyone running the Brembo setup on their cars, perhaps stuffing an additional shim on top of what's already there, and eliminating the goop to let things move around a bit more could help. It's likely the rubber coated shim is what did the trick as the factory supplied metal shim did nothing to quiet these brakes.
