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.
