Are there any ways to correct the 6's tendency to become a little unstable on curved roads with bumps in them? I often notice that when I am going through a curve on a roadway that has expansion joints or something similar, the car does more than simply bounce upward. It tends to drift outward or inward a bit once the front wheels hit the bump. I haven't driven a lot of RWD cars (this would be my first full-time RWD car), but this tendency is much less in a FWD car, which, of course, tends to continue tracking at the front and rear in a predictable fashion when hitting a bump during a curve or turn.
