Tony: I had a JUN flywheel and ACT clutch in my Nissan. The ACT was a 6-puck unsprung and it was a pain in the a$$ to get around with mainly on hills, and if cars got to close behind me. The thing revved awesome though. I later went to a Fidanza flywheel and JWT clutch. This was much easier to get around town.

I think as long as you get a strong SPRUNG clutch you will be good to go.

I will be upgrading to a Fidanza flywheel and slightly stronger than stock clutch when it is time in the Z. The car revs pretty quick now, but the flywheel just makes a world of difference.
