I just dropped a Fidanza in my FR-S with an Exedy OEM replacement clutch and Driveshaftshop aluminum driveshaft.
I've been thus far surprised at the driving characteristics. The only time I notice the lack of rotational inertia is how quickly revs fall from high RPMs. Starting from a stop is not at all difficult.

If you're considering a flywheel and are expecting the Fidanza to behave as it does on lower displacement or lower powered cars, it doesn't.

I have noticed quite a bit more drivetrain noise below 2500 RPM. It sounds like lugging up to about 2200 RPM. Makes some sense, but it is a negative, as that's around-town RPMs. I think the one piece driveshaft probably contributes to that.

Anyway. That's my thoughts. Please comment or ask any questions.

I had a similar opinion after getting mine installed - didn't seem to make much noticeable difference to performance. I've also noticed a lot of noise under 2500 RPM as well. Tempted to swap back to the stock flywheel just to get rid of the horrible noise tbh
