Thanks for all the replies. Makes me feel really comfortable. Tbh when i got my car i ordered a base but they ordered a sport on accident so i got the upgrade for free. This happened and i thought i was given a bait and switch of a lemon. I feel comfy now and will floor my baby with no worries xD.

@DoomMonkey Ill try to upload a clip when im driving with someone during the day so they can hold the camera. I work pretty late so maybe this monday. Thanks for your interest

Between the torque converter un/locking, transmission shifting, and the automatic throttle blip on downshift, things can feel funny at low speeds. As the other have said, that's normal for the 370Z. Unless it turns into a thunk, stop worrying and :driving:
