Parts aren't the problem, it's GM admitting they have a problem with this rear end. It's their way of punishing anyone who questions their techno baby. 
Look at the major list of vehicles on the TSB list for this limited slip piece of work, the 07 is already on it! It's not an issue of a bad batch just a bad design and a failure to admit the problem. Limited slip additive what a joke. I wish I had my C5 back.

There are a few lemon law attorneys that will listen to your situation and assess it for free. A letter on legal letterhead might get them moving.

They don't quite understand everything about vettes, but with my help they are learning. I've had the car in the shop a few more times for the fuel service issue, the nav system issue, and will be taking it in soon for the a-pillar interior material delaminating.

It will help if you go to User CP, then Edit Options, then look for the pull-down shown in the thumbnail below. Then select 100. Problem should then be solved.

I bought my car for recreation and a little track time is part of the package for me. I truly feel short changed after giving this kind of money for a car with these kind of problems.
Bummer. Very sorry for the trouble. Do you think run flats had anything to do wth this? I surely cannot think about why, the most trouble you can have is hooking up too quick under alot of stress, run flats are known not to not give that kind of traction. This is odd to be sure.

I know this is a slightly different scenario, but a buddy of mine wrecked his C5 at a NCCC autocross a couple of years ago. Initially Farmer's Insurance denied his claim because their position was that he was racing. He eventually convinced them that the autocross was basically a sanctioned car club's "driver education" event. Why, if someone happens to have been at a drag strip and a GM service tech claims that the car was raced at the time of the rear-end failure, could the owner not claim the same thing?

[QUOTE=DrivnXcitment]Well for starters let me tell you how. I have an 05 BONE STOCK C6 Z51 6spd. I dropped the clutch at 1100-1200 RPM (that's no joke it was really that low). I just don't understand how this could have happened on street tires (the Goodyear Runflats) that were not heated up.
I thought that you are suppose to slipped the clutch at any RPM when launching. But dumping or dropping the clutch, you're bound to break something on any car with a stick. I doubt that the stock runflats had anything to do with the breakage. Anyway, parts do break. I hope you make out well on the warranty issue.

Might it? Yes
Rears have broken with and without the cradle.

I don't know whether it works or not, but if it is installed incorrectly it will ruin your rear. Cheap insurance? You mean they will pay for a new rear if it breaks while it is installed? It may not cost very much, but it is not insurance.

No of course I wouldnt expect them to pay for damage. I just mean it's not alot to spend for any protection it might offer. Seems like a worthwhile option over leaving it as-is or an entirely new unit.

"I was doing some spirited driving and all of a sudden it broke." Or better yet, just trailer it, or have it flatbedded to the dealership and tell him simply, "It broke" and don't get specific.....
You have a much better chance of getting it repaired under warranty.
On the other hand, if you have that brace installed and your differential still breaks, you can probably forget about taking it back to the dealer and attempting to have it repaired under warranty.
The minute he sees that cracked differential case along with, and inside of, that brace, he is probably going to refuse it as a warranty claim. He sees that brace and he is going to know that you were probably racing the car when it failed. Or he could even try and argue that the brace itself caused the failure as it is aftermarket equipment which is directly bolted up to the differential.
