What did you drive before your 370z?

Bottom line, it should not wander like that. This car, stock, should feel very planted, especially since it pulls nearly a full g in cornering tests. I would start looking at bushings that keep alignments of the suspension true and connected to the car. If subframe bushings are whacked could it cause slight misalignment of the entire rear with the front? Just a thought. Course, bouncing like a basket ball sounds like shocks. Heck, at 2009, could be both.
