I doubt it, just makes you rev a little more off the line to store enough energy to launch the car with the lighter flywheel. If it's off balance, it will get worse when you rev higher. If it's not off balance, I'd check out a lot of other things before worrying about the flywheel. Have you done a power balance test? If all cylinders aren't firing evenly, it will cause vibration that gets less noticeable at higher revs.
