Beefing up rear end?
I've heard so many stories of rear ends goin to crap, im now afraid of stomping on it or taking my car to the dragstrip, for fear of embarrassment. I have a 2005 Z51 MN6. Is there any way to reinforce it without rebuilding the whole rear and goin broke? Someone mentioned something about a girdle but I dont even know what that is or if it would fix the problem. Any ideas?

Yes and no
I asked the same question to Andy Green After He finished my car and it was making 542 crank HP. His answer was this; If I'm just going to drive it on the street with street tires, then you don't need to do anything to the rear end. Reasoning, the tires will never hook with that kind of power. So spinning tires means no rear end damage. Now if I was going to the drag strip and using drag radials and hooking that kind of power then yes you had better strengthen the rear end and put hardened half shafts in. And you still may break. Even LPE with there 750HP twin turbo 427 don't do anything to the rear end, because they know it will never hook up. Check out this months Motor trend on super tunner cars. With 1000HP cars there 1/4 mile times weren't but a few tenths faster than a stock Z06. Some even ran slower. Reason, was they can't hook up that kind of power.
