wats up i have a 1992 camaro rs 5.0 when u take off hard the rear end feels like it is twisting i was wondering if the torque arm bar maybe the reason of the panhard bar the only does when u hammer on it any help would be great the vibration goes all the way back to the trans from the rear to trans thanks

 

The rearend connected to the torque arm...
The torque arm connected to the trans tail...
The trans tail connected to the trans mount...
The trans mount connected to the crossmember...
Check your transmission mount. If it's split apart, the torque from the rear will lift the tail of the trans and just cause trouble. If bad, replace it with a polyurethane mount.
