I'm almost certain CSC failures correlates to how you drive. I mean there are guys that replaced their CSC 3 times. But I do admit that stock CSC is total garbage.

Then show your work. There's plenty of people who have had them fail across all levels of driving skill. What proof do you have that it's in any way related to driver skill?

Agree

CSC failing due to driver skill..:rofl2:

Read through that entire thread and tell me not a single one of them knows how to drive a MT Z properly

The fact that some CSC fail and some don't is the proof itself. Yes the CSC is sensitive but the fact that some are still working fine means something's done properly. The Z is actually a hard car to drive stick so I can understand why people have hard time with the clutch.

You tell me why mine is still working and I can guarantee you it's not matter of luck. I can also can guarantee you that I use the clutch more than anyone else in this entire forum because of my daily stop-and-go LA traffic. I press the clutch every 3-4 second for about 45 minutes straight on the I-405 freeway everyday.....and that's only 1 way. And guess what, my stock CSC is rock solid even after all the years of commute.

I guess the real question is "why hasn't my CSC failed yet?"

We live in a probabilistic world. In any high volume product the same course of actions and conditions will result in many different results.
Some are more robust than others.

There are also many more variables at play than drivers skill - driving conditions, how hard you drive, weather where you live, the list is literally endless.

Edit: I came off too harsh the first time. So I edited.

How is this ridiculous? I'm telling you my honest experience with the CSC. And it's a darn good one too. Yes there are more variables but it ultimately boils down to 2 things. The quality of the CSC and how you drive it. The fact that you're not even considering my legitimate and plausible experience is ridiculous.

I came off too aggressive and edited my post. Sorry about that.

What I am saying is that your experience is only one of thousands, to draw a concrete conclusion over completely subjective reasoning (essentially "I am a skilled driver") is, for lack of a better word, silly.

Again, sorry I came off so poorly before. Not trying to be "that guy."

I think anyone who owns a MT "Z" will at some point "drive it like you stole it"...

At that point you're playing Russian Roulette with the stock CSC.

Thus I went ahead and CMAK'd that sumbitch :-)

Apology accepted ;) And I also didn't mean to come out as "hey look, I'm a skilled driver and you're not" guy. If I offended anyone, I apologies. But I'm a firm believer that the way you drive has a direct correlation to the CSC failure. I also have no say about those who heavily modified their Z (TT, clutch, etc). I only have couple basic bolt-ons

that's good to know. How many miles do you have and how often you change the clutch fluid? Thx.

I drove my 12' Nismo to over 60k with the stock CSC. When I got the car the clutch fluid was completely destroyed at 19k miles. I had to change the fluid every other oil change to keep it clean until the last 10k miles. MY 13' Nismo I got with only 77xx miles on it. The fluid was already done on it. I only had to change it out every other oil change for 20k miles before the fluid started stay clean. I used Motul RBF 600 fluid in both cars. I did have an issue last year in winter with my 13', the pedal went soft coming out of my drive way in below freezing temps. I changed the fluid again and haven't had an issue since. Proper maintenance does help. That doesn't mean I don't have a brand new clutch/Flywheel/CSC sitting in a box at my house though. :)

I have close to 70,000 miles on my Z. I never changed my clutch fluid yet but I do maintain the optimal fluid level.
