C6 rear end wobbling
I tried searching for this with no avail. Maybe you all can help me out.
This mainly happens when I do WOT 0-50 or 60 MPH the rear end starts wobbling left and right (or up and down from left to right) noticably once I go past around 50 MPH, it feels as if it's the suspension.
OR if I go WOT from 50-80 etc... it seems if I go WOT from any speed and hold it, the rear end will inevitably start shaking. Tires are not burning out or losing traction.
Once I let go of the gas and set it on cruise it's fine, even at speeds over 100. I just haven't been able to figure out what it may be. My car is also past it's warranty, (42K miles). My tires are near bald, but I don't know if that would be causing this. I appreciate the assistance.

Just a quick thought.. I had wobbling in my rear tires once over 50 mph. I had my rear rims and tires re-balanced and it went away. The tire tech informed me that my wheel weight had came off.

Your kidding... Right? 
Sounds like wheel hop...and no traction to me...Wide open throttle... does that.

It can't be that, I used to be able to drive like a bat out of hell without any wobbling of any sort.

If everything is tight in the rear end the only thing left are tires and or wheels. If it was wheels it would be constant so I don't that's the problem. Sounds to me like some new tires would solve your problem. Shouldn't be driving around on almost bald tires anyway. VERY dangerous if you have ANY moisture on the roads.... Traction control or active handling isn't going to save you with bald rear tires...

Might be a good idea to check your rear stabilizer bar mounting bolts - another recent thread in the Z06 section described how a few C6Z owners found bolt(s) missing and brackets bent...

I need new tires, BUT I'm planning on selling the car soon. I know I will buy a C6 again in the near future. (maybe a Z06 in this economy) I just didn't want to think that after the warranty the C6's start having major problems. lol. So i'm going to tough it out on my darn near michilen pilot "slicks" in the back till I sell her.
On a side note, Surprisingly the michilen tires are leaps and bounds better than the stock good years. In the snow and ice this past week I didn't crash cause of bald tires
thanks again everyone, It seems as if it may be a small problem that I can let fly. As long as I don't mention it to the dealership that may be buying it

How about loose axle nut? Have you had them tightened?
