65,000 miles original csc. RJM pedal installed at 55,000 miles. Bleed clutch once a year.

60K miles, factory fluid, never serviced changed. I do have HFC's on the car. less heat? Flip side, Supercharged, factory clutch 30K miles SC. I have a triple disc and Z1 CSC on hand if the stock unit fails.

2009, Master Cylinder followed by CSC.
74,600ish miles.

Replaced with Z1 Motorsports CSC Elimination Kit and Road Race clutch package (had the tranny off, so why not?).

Overall, with the new flywheel, clutch and plate, this thing feels WAAY better!
Solid consistent clutch release, stiffer( which is a given I guess).

Be warned though, with the lighter flywheel it is bit noisier at idle.
Also get a little bit of noise below 2,000-2,500rpm.

I had some slippage in the past with the old CSC, replaced fluid and was able to nurse it for awhile, but honestly I would just replace it if you can before you end up stranded on a road trip or something.

I have only had the Z1 kit for a few hours, but I'll try to answer any questions or post a updates as I wear it in.

I still have the original at 5800 miles. Ive been waiting for it to poo the bed since I drove it off the lot, but I'm not messing with it other than bleeds every oil change until the warranty is up our it fails. I almost hope it dies under warranty so I can get the z1 in there while the trans is off if the dealer is amenable. Almost. It would be a good excuse to be late for work, but chances are it would die 400 miles from nowhere at 1am and no cell signal to call a tow.

I'm afraid to post in this thread, my luck, it'll go out tomorrow.

If it happens it happens. Stash the cash and you'll be ready. I want it to happen like others so I can throw in a z1 and then other goodies while the trans is out. :cool:

...don't forget the faint sounds of banjo music in the cool night air.

I have a 2009 with 85K on it and still no issues! :happydance:

2011 with 43k just recently had the clutch fluid flushed for the first time after losing almost all hydraulic pressure (no leaks) with the GTR brake fluid - all seems well so far.

It is so weird how random this issue is. But like mag_black said, I am not going to say because it will most likely break after saying so.

I am the original owner of my '09. Have the original CSC, just turned over 55,000 miles. No problems with the clutch. Keeping my fingers crossed.

I didn't make it
 

Mine began to fail around 32K miles. Constant problem. Dealer would not fix and then the warranty expired before the 3rd failure. I just bought a 2015 and, when I make it to 36K, I'm getting the hd replacement pronto

its sad that nissan will not recall the z34 and get this replaced!

They wont ever do a recall at this point on it, cause
A they would have to fix everyone's MT car.
B they would have to reimburse everyone that has paid out of pocket to have it done, some more then once... :(

Lets just hope they fix the problem with the next one

This has been on my mind lately since...2013 - now 30 months old/62,k miles. So far book scheduled maintenance. Daily spirited driven.
