How many of you have the original csc?
 

I was reading the csc's problem thread, apparently it affects all MT units.

"Only" 108 members are in the failure list, but there are more than 130k members in the forum...

How many of you have the original csc? how many miles?

I'm still on my original for 5 years now and 80000 miles:ughdance:

Nope swapped mine out when i put a twin disc clutch in. But oem one had 33k miles on it with no issues

I'd be curious to see who has the highest mileage factory CSC. I'm only at 19k but no issues here.

Lucky!

Just turned 40k. No issues. Thank god.

I remember reading some guy had like 120000 miles on his before he had to change it. That's the highest mileage I've heard of.

30K 4.5yrs and still going even with lots of hill starts and NYC traffic and a few track days.

Im on my OEM CSC at 36k for 4 yrs now. I autocrossed the car for a few years now on top of summer daily driving.

My CSC was going strong with 51K miles when I installed the Z1 kit.

My CMC on the other hand has been replaced 3 times in 70K miles :wtf2:

50K and still going, Knock on wood.

Well, 51K now...LOL

G37, but I'm at 60K and fine.

Yep, that was me, lots of hwy driving, stop and go, in theory will ware it out faster.

Also noticed with a aftermarket clutch assembly it will kill a stock CSC VERY fast.

First OE one I got 133,000 miles, the current OE one i'm over 64,000 miles on it. found my old invoices....

They've only sold about 60K Z34's give or take 5K.

So the forum census doesn't reflect owners. Maybe half of the 60K are here.

I have the OEM, but already had my clutch fluid drain out at 32k miles. I am now at 38k and have the Z1 Speed HD CSC that will be going in very soon. I don't want to take the risk of having the fluids leak out again...

Only 24k here, still on stock for now. Though I have money stashed away to have it fixed when it happens.

So like most of the highest mileage questions, 90ST wins this one.

Factor in the AT guys too... leaves about 500. lol:driving:

2013 OEM at 35k right now

I put in RBF dot 4 fluid.

I also track it occasionally.

My '11 has about 30k miles and there is no problem with CSC. I don't know if the previous owners had any trouble with it, but it seems that the bellhousing was never opened. I assume the clutch assembly and flywheel are OEM and never replaced.

26,000 miles, bunch of trackdays. :driving: I've drained and refilled mine with Motul 600, and put insulation around the line, down by the exhaust too.

47k hard driven miles for me, still good. Feel like I pushed my luck to get this far.

5y - 60k miles, daily driven, occasionally hard driven, and still OEM CSC. No issues.

237 miles, and my fingers are crossed. LOL

Seriously, if this thing goes it's aftermarket for sure, 2015 under warranty or not. I'm not having them rip it apart multiple times because if a known problematic part, if mine does go. Plus then it's ready for boost.

50k, 5 years, and ~10 track days. i flush my fluid before every track day which helps a lot. the fluid is almost always dark brown/black. shifting gets a lot smoother as well!

41k miles and still clutching in NYCs traffic, i gotta flush my fluid i think the last time it was done at 26k miles.

Fuel pump went first. So yeah watch out for em faulty fuel pumps. Cuz you might burn ur cats.

swapped it out just to be safe at 7200 mi. Added the GT-R fluid as advised. You can feel the difference.

2009, 35K keep fluid spotless clean so far no problems.

2009; about 76,000 miles. Clutch master cylinder just failed; betting that CSC went with it.

Time for new everything. Joe at ZSpeed took care of me with one of those nifty kits.

4yrs 52k but who knows tomorrow.

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.
