I've been following Grand AM kind of closely. I noticed that a lot of the GS cars are required to run stock parts. You can't get crazy with it. So, I found it interesting that with the stoptech kit 332mm, they experienced no fade, etc with the car ... and using stock rear brakes.

I wonder what brake pads they used for the rear?
