^^Used master cylinder with 60K miles?!@#

I wish you luck, hopefully you'll at least be able to bled the thing.

I realize money is tight, but redundant labor costs even more. For the master or slave, only new parts. Anything else is asking for trouble. Lets hope you can at least get some use out of it.

Brother, im gonna be honest with you, I only went with redline because Joe from zspeed said so, I've heard its really good stuff, but I dont know anything about it personally.

The Motul 600 is good stuff too. But boy, the sh1t is expensive. Its like $20 a quart. (and thats on ebay)

I bought the redline on ebay as well.. and saved money on both.

eastwest2300 · 08-04-2015, 11:48 AM

I honestly couldnt tell you if one was better than the other.

ShutokuZ · 08-04-2015, 01:05 PM

I am a firm believer in Redline products. I used MT-90 in the trans and 75-90NS in the rear diff of my Evo. Great stuff and it deffinately quiets things down. The Evo has extremely notchy trans, and the Redline gear oil smoothed it out.

Jsolo · 08-04-2015, 01:55 PM

I've had mixed results with redline mt85. It was great when I put it in (spring), no issues that coming winter. The following winter after ~8K miles however, shifting in the cold was very difficult. Temps in chicago fluctuate greatly in the winter.

The first 5-10 minutes of operation when near freezing temps (32F), shifting was very difficult. In fact, I had to go 1-3 until the car warmed up. Double clutching didn't help either.

In the middle of january I switched back to the OE nissan fluid. Shifting problems disappeared. Being a high performance synthetic fluid I would of expected it to last longer than 8K. We'll see how the nissan fluid does this winter.

eastwest2300 · 08-04-2015, 02:04 PM

I will say this, Joe from zspeed was right, I dont hear any chatter with my new clutch & flywheel. I did get the "silent" option when I ordered everything.

I understand the silence or quiet but I mean is that it? I'm wondering how well it protects the mechanism and how good does it handle temp? As well as smoothing out shifting... Isn't that what should matter most?

For me, I just wanted something that works, knowing that the transmission had to be opened to replace the CSC, I thought I'd myswell upgrade the clutch & flywheel, I didnt want to deal with chatter, and for $50 more, I figured it was worth it.

Im not sure why these components cause chatter, but they do.

Are you running the stock clutch?
One of the members on here had one fail but he was running an aftermarket clutch (higher clamping force).

Good question. I've also had my HD CSC for about two years, but with less mileage (approx. 5K). No issues to date. However, a couple of questions for you:
First, did you replace the CMC at the same time that you installed the HD CSC?
Second, are you sure that it's the CSC that starting to go and not the CMC?
I'm only aware of one HD CSC failure, and that was Chuck who coupled it to a Spec clutch, and evidently the combination did not work.
That said, It's still a good question, and I'd be interested in hearing from others who have installed the HD CSC from ZSpeed.
