Just like it says, I'm looking for a the Ls1 rear brakes to put on my thirdgen. I'm interested in everything from the backing plates and parking brake to the abutments, calipers, hardware and rotors if they are in decent shape. Hopefully someone did an upgrade and has these parts laying around. I'm most interested in a complete set-up, but I will consider partial as well.

Thanks in advance, Austin

What kind of axle do you have? I'd like to do the same...I've collected parts for the fronts, but not sure
how to address the back end. Any thoughts appreciated.

I have a 3rd gen with a LS1 4th gen axle. I could be wrong, but I doubt the brakes would mount properly to any of the various 3rd gen axles. The extra space for the park brake drum and the ABS sensor ring results in about 1.5 inches of extra width on each side. It might work, but I've never heard of anyone doing it. Previously, when I was running a 3rd gen 1LE 9-bolt, it was possible to mount the similar PBR alum. calipers, or any of the lesser factory brakes if the correct mounting plates were used. This is also true for the 3rd gen 10-bolt axles. You may want to switch to a 4th gen axle complete with brakes as I have done. The only issue is that it will need wheels with 4th gen F-body or Y-body C4 or later wheels. Another option is to buy the 1LE PBR rears and mounting plates (the plates are hard to find, but I have a set (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif) that are surplus). These brakes are almost identical in function to the 4th gen factory brakes which are PBR as well. Hope this helps.
