hmmm, your back might be too lose, do you hear skipping or shuddering from the back? if your camber is bad enough then your FWD could have been accidently set up for RWD drifting... ie: front tight with negative camber, with loose backend... hmmm i dont know what to tell you, have a friend follow behind with a camera, make a turn and film you throwing the back end out, you might be able to spot the problem externally.. thats abotu all the help i got
