I've read that somebody here also have the same problem with their Z but most do not have that. So is it something wrong with my Z?
At 99 mph the car should still feel very firmly planted, yes. My experience is with the sport model's front spoilers (the long under-chin plastic spoiler that faces straight down, and the two little air dam flaps in front of the front tires), but honestly even if those were removed I wouldn't think you'd feel any lift at 99 mph. Is the undertray off the car maybe? (the one you remove partially or completely for oil changes?).
