I found a thread from a while back where a fellow member, BBU.COM, was selling a nice bracket for this conversion. Does anyone know if he is still making these or if they are available anywhere else?

Thanks for the help.

You have to be careful if you're running a floating axle, like our ten bolts. You can end up with severe caliper bind unless BBU has created a solution. I'm not putting fixed calipers on until I finally bite the bullet on a 9".

 

Those don't look like something BBU would produce. And by the A or AE cut into them, I suspect they were manufactured by someone else, and Scott (BBU) might've been using them as a template to create his own conversion parts, then he sold them. Email him. This is the thread.

They look like a formally produced version of the ones 87350IROC crafted. His renderings are shown at the bottom of page 1 of his thread below, and the products are shown on page 2. He made them in 2012, and he apparently was selling them, so maybe those are the final version of what he was selling. Looks like he last logged into TGO about a year and a half ago.

I gotta say that's some impressive memory recall right there!

 

These were a design by a guy named Ryan down in Florida, they used the CTS-V plates and were done nicely, I helped him with a buy in on his first run and thought he was going to continue since I had bought 10 sets and he sold a few setups through my website- but I'm not sure if he ran anymore after that or not, I know he had a website and was doing other brake brackets and some motorcycle parts, I cannot find his site anymore. I do have a set of these left if the OP wants them. We had been working on a 5th gen Camaro ss based conversion that was more modular than this one, it could be ran without the parking brake for cheap and that parking brake could be added down the road, these are the same ones I still produce today (which will hold the cts-v brakes as well). The SS plates places the hook in a "normal" location under the axle tube, where the CTS-V plates place the hook in a vertical pull direction. The AIE plates are nice, Ryan wanted to just sell them with all the components (rotors, calipers, pads etc) which I had tried steering him away from because I know third gen-r's, they like sourcing things themselves, Ryan felt that a all in one kit was the right thing to do but the 1800 price tag was more than most wanted to go in on.

Here is a V caliper on the camaro SS plate, this one is set up to lead the axle with a fwd pull to engage, that option to switch the pull direction is useful as well as leading or trailing the axle becuase alot of the rear calipers have staggered pistons, including the V`s
