Yeah, call Tobin. I think I talked with him for about 45 minutes the other day.
Basically here were the main points of what we discussed.
1. small bore master cylinders work great on cars with no knockback. a dual master setup, which I believe he said could be found on later g-bodies, would theoretically help, if you still wanted to run manual brakes.
2. rear brake size. As others have said, we don't need huge brakes in the rear. Still, a lot of us, myself included could use more rear brake. I lock up the fronts way before it will ever be possible for me to lock up the rears, and I'm not running a proportioning valve now, which means, the major limiting factor on these systems is still the type of tire being used. That said, I don't think you'd want the base C6 floating calipers on the rear of your car because you'd have way too much brake in the back. While the C6 floating front calipers aren't physically large, their total piston size (as far as I can remember) isn't appreciable different than the 6 piston Z06 fronts.
3. axles, bearings, etc. Everyone agrees the full floater is the best solution to this problem. It may be expensive, but if I could do it all over again I'd probably just get one instead of wasting all the dollars and time I have so far. I don't know if you have a rear axle assembly sitting around already, but if you do, check it to make sure it is straight after being welded, that may make a huge difference. Also tapered bearings seem to work better than roller bearings, although Tobin seemed to think the SET20s that now ship with DSE (Moser stuff) will hold up better than the ones that shipped until late (maybe) '09.
You have some kick ass rear brakes, and I think given the right bearings, and master cylinder, you won't have to worry too much about knockback.
