Many Audi guys with built engine big turbo apps (GT3071) have run Spec and they all had problems and in fact I have never heard of anyone not having a problem with SPEC clutches. Not sure if the problem carries over to the 350z but if the Audi SPEC clutch is even half true about problems I would avoid them like the plague.

By the way, i got my info from mynismo.com

Unless you get one with a pressure plate that requires the foot of god to push it in.....

And, as you just read from Z1, any organic clutch that will hold that power is clearly not streetable.
When I was originally looking around for a clutch, I was told that the RPS 6-puck combo was underrated and could hold close to 700ft/lbs. Seeing Jeremy's car tear one up and slip totally past 470whp cured me of that belief real quick...

We still know exactly which clutch Jeremy was refering to. The RPS 6 puck with heavy max pressure plate is a beast, and I really dont see it failing at 470whp.
The CM twin plates are designed strictly for drag racing, according to CM, and they can "easily" hold 800ft/lbs, according to CM.

According to Clutchmasters the FX600 is streetable and the FX700 is Track only alot of copper in it and it grabs hard and quuick.
FX600 = Bonded Organic Kevlar mix for the street
FX700 = Compressed Ceramic Bronze for the strip

Cool over 800ft/lbs at the crank,sounds good; way more than I need. Cheaper than the twin or tripple carbon and holds the power.

I have a clutchmasters with ceramic lining and a jwt flywheel. I drive my car daily, is a little difficult to get used too, but its a pretty strong clutch. They dont show it on the website you have to call them and request it, and the price for it is unbeatable.

I really like the feel of the clutch. The pedal is fairly light and the engagement point is in the stock location, unlike the JWT which drops right to the floor. The engagment of the clutch is a bit quick and slipping the clutch for a smooth start takes about 1/2 dozen times to get the hang of. If the clutch shows to have some longevity it is a real winner- being a hybrid carbon-kevlar makeup, it should have some longevity.
I would choose a spec setup over a clutchmaster, though clutchmaster is a somewhat overlooked brand, much like Spec.
I am looking for a bit more power and will push the spec 2+ to beyond 500 wtq and run it till it fails. At that time, I 'may' go with an ATS setup, but will definitely chat with the fellas at spec about their 3+ when the time comes
Oh, and the spec flywheel, well it is a JWT/fidanza flywheel. Says JWT on it

This guy has a Clutchmasters FX700 for sale for $1000. If I didn't already have my FX600, I would snap it up. FYI, I am very happy with my FX600; it is smoother than I expected.

See my post in that thread, maybe you can exchange the FX700 plates for the FX600 plates, which are supposed to be more streetable. It is my understanding that the clutch plates are the only difference between the FX600 and the FX700... At any rate, $1000 for a FX700 that has never been used is a very good deal...
