Did you try it with the VDC off? U should notice that the shifts are smoother.
It seems a lot of people on this site are "afraid" or "discourage" people to drive with the VDC off
..And they are right! If you are going to disrespect the car it can be horrible. I don't race and I don't shift passed 4000 rpm...In the snow/rain/ice/cold the VDC should be on. That being said I NEVER had it on with my previous car G35 6mt and I turned it off day one in the 370z.
The shifts are much smoother with the VDC off
