So far what it's looking like is a combo of getting the new slave and removing the restrictor, and at the same time replacing clutch/flywheel due to whatever damage had been done.

Seems like a lot have been popping up on the forum, but I doubt all HR owners frequent any Z boards. I think it's bigger than we realize, but still not big enough for Nissan to recognize the problem (or, from what it really looks like, is they believe it's driver error). I'd bet there's at least 1 HR per dealership that have had to come in to get this done. Has anyone asked any of the dealers on here what they think/how many fixes they've had to do?

Loss of clutch pressure usually only happens if the fluid boils, which shouldn't happen with new fluid on a new car under normal conditions.

3,000 miles on mine
Just did the Oil Change yesterday.
Compared to my H22 'Lude, I hate how the Clutch / Shifting experience feels on the Z, I dont know if all are like this, but sometimes it is smooth and sometimes notchy, and very notchy at times... I am still very self-conscious trying to learn why sometimes it is smooth and sometimes notchy.
Anyways, I have not been experiencing any loss of pressure on the pedal, the only thing is that the grab point is really high but I think that is normal.
Well, to the day I can count in my fingers how many times I drove it hard and only taken it once to redline. I just filled up the tank, I will be driving it pretty hard now to see if it will hold.

It's not a boiling issue either, the hydraulic system loses pressure somewhere (I suspect the slave). You could pump it to get the pressure back up and it would bleed off again 5 min. later. All of this was regardless of operating temp.. it could have been when you first got in the car in the morning.
I haven't had my pedal stick since I got it fixed the first time, but it isn't right either. I get clutch slippage from time to time..like during the 2-3 shift... it just shouldn't do that.

NNNOO!! Not sure If I am getting the disease so I need advise. I have only 13K on my car now. Lately when I am at a complete stop and start to accelerate, I will start to release the clutch while accelerating as usual but the car starts to shake and it feels like the clutch is slipping but isnt really(or at least I think). It just kinda feels like the Tranny/ and or clutch is shaking while the clutch engages but only occational upon a stop and go. Any advise?
Im just pissed cause I know when Im going to go to the dealership it probably wont repeat the problem and they wont look at it.

I'm having a lot of the chatter.... I removed the driveshaft (which was vibrating violently) and the problem persists. I believe is coming from the output shaft of the transmission.... I'll keep u guys updated

When I had my Z the clutch chattered from day one. Every Z I've been in also had chatter.
You should be fine (as long as it doesn't actually slip or stick to the ground).

try launching at a higher rpm, your clutch is slipping/grabbing/slipping/grabbing.
higher RPM will let it slip until its ready to grab.
alternatively you can launch at the same rpm just take it slower.
