2009 370z Touring Sport - Intake, exhaust, springs, DBA rotors, brake lines (265 Front and 285 Rear).

Off topic because I wanted to see what you all think since you guys come from different types of cars etc.

Anyone experience this? I came from a very agile RWD car that stuck to the road like it was on rails. My Rx8, because of my setup, had more grip than the 370Z but that's not my issue. I just feel the 370 is all over the place at high speeds. Alignment is stock. This car bounces like a basketball whenever it hits a bump at 60 + mph highway speeds. 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).
