We have a 2011 Nismo Z here using this kit:
Z1 370Z / G37 Clutch and Flywheel combo
I can't comment on longevity but it does drive very nicely. I believe it uses a Exedy clutch disc and an upgraded pressure plate. Pedal feel is kept very light like the OEM clutch but feels great with the upgraded CSC. They rate it at 500wtq, we pushed it to about 380wtq with the Stillen kit. It engages very smoothly and the Organic disc allows for some slip. You might not get the lowest 60ft time but this clutch seems to be able to hold some power.
We did not have good success with the ACT HDSS unit we originally utilized in one of the twin turbo cars we've built. We switched to the OS Giken twin disc in that car recently. It drives nice but it is very aggressive engagement especially when cold. I bet you could rip a 60ft with it with the right tires though!
A few of my supercharged guys are still on the stock clutch. They have pretty conservative driving habits though.
Thanks,
