I think in most common cases you're right that dropping rear weight will tend to shift the car in the understeer direction just due to basic inertial stuff. However, you also have to consider that dropping rear weight can reduce rear traction in some scenarios, which would tend to produce more oversteer.

This stuff is always way too complicated for me to fathom the complete dynamic picture. I guess that's why I'm not a car body/suspension engineer
