CM Noise from the rear?

I have a 2007 coupe and I am hearing a strang noise which appears to be comming from the rear of the car durring slow speed, sharp turns (at first just left turns, now right and left turns). The noise sounds like wheel rubbing or someone scraping a stick on a sidwalk. The noise also seems to be less noticeable after I have been driving for some time. I have checked for rubbing and have not found any. Also, I had someone listen for the noise who confermed that it is indeed comming from the rear. What could this be? Is it possipal that it is clutch noise from the diff. and oil addative can fix this?

Thanks

Probably the differential needs some additive or a fluid change. See this TSB:

I had the exact same problem with my 2006 Z06. I took it to the dealer and the performed the procedure described in the link that BruceF provided. I haven't had the problem since.
