I have a fidanza flywheel and I love it. I sure revs up very quick, and yes it does also lowers your rpm quicker when shifting. - But in all I think it is worth it, -just have to shift quicker - plus it really helps when accelerating around a corner in a track.
and no i don't have any drivabilty issues for my everyday driving.

i love mine so far, but i read somewhere that there was a aluminum one for the K series motors that was 11 lbs, i think it was ZEX or something like that and there was another at like 7 lbs, i think it was the clutch masters so you can pick based on what your doing how light you want it to be
