I have the JWT lightweight flywheel and clutch package on my Z. And the flywheel does have a replaceable contact surface.

In other words, the rpm will seem to float more (not drop as fast) as you press the clutch to shift from one gear to the next. I don't like that aspect, so personally, I always stay with the stock flywheel in my cars.
I never really noticed that in my Z, but then again its not something I would look for either. The biggest difference I have noted is that it does accelerate a bit faster because of less rotational mass. But on the downside, it doesn't slow down as fast due to the same reason. Not really a big deal, but when my club is doing canyon runs I definitely notice I have to use my brakes more than I would like......So big brake kit in the future....I think so
