Beefing up 05 Rear
I'm on a path to strengthen my '05 rear in order to withstand some a boost application. I've tracked my car with the stock components a number of times with close to 400rwhp. I recently went to ECS and had them install an LS7 clutch, hardened output shaft, and 4.10 gears. I wanna be a little cautious so I don't get a supercharger installed, then have it blow up some drive train components a week later. What else do I need to add help with my rear handling that sort of power? I was considering having ECS install the Z06 diff. Had I known I was planning to do a supercharger, I would've had them do the diff when I was doing my gears 
Thanks

The internals of the 2005 case arent the weak link, its the case itself. There are 2 options: A C5 rear diff or a 2006+ C6 rear diff which requires the rear trans case to be swapped too. I have the C5 diff and I'm very happy with it. It takes sick power levels with r-compound tires and even survived some serious wheel hop. Even if I break the diff, the C5 core is 700 bucks as opposed to the C6's 2100 dollar core charge.
I have 2 hardened shafts and 4.10's. Cartek installed the C5 diff with their custom center mount in my C6 2 years ago.........Miles of smiles. Aintqik's 761rwhp 2005 C6 runs the same diff as mine. No issues there either.
