I also have to make constant steering corrections because the rear end feels like its wondering left and right at high speeds 80 + mph. Keep in mind that it did this on stock suspension. Then I put springs and camber arms in the rear. Still all over the place. I mean hasn't anyone else noticed this or am I too picky?
I've taken it to a shop I trust and they confirmed that everything is OK suspension wise. So is this normal for the 370? I am getting close to the point of just getting rid of the car and buying a project car (Either Monster Miata or Rx7 FD3s with LS3/drysump swap).

Now that I think about it, the diff bushing may not actually cause the wandering you talk about, could I suppose but... How about rear subframe bushings.
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.
