Sticky: (Official) 370Z Clutch Pressure (CSC) Failures

ShutokuZ

I don't mean to bash on your purchase, but XTD clutches do not hold up for very long. Most threads I have read complain about the disk friction material disintegrating and turning to powder, leaving nothing but bare metal on the disk puck or the pucks not wearing evenly. Also, they start to slip quick and don't provide the advertised clamping force/TQ numbers. The previous owner of my old Evo put in a XTD stage 4 with a sprung disk, and the springs actually seperated from the disk in 4k miles! I didn't know what was in there until I had it pulled and replaced with ACT. I will post a pic of the disk when I get home.

Well it's what I could afford in the mean time and I need to get my car quick so I'll give it a try any way and it comes with a warranty too so I'm not worried

Yeah bro I've never heard of that brand, thats definitely half the cost that I paid for my setup from zspeed, I'm not sure if ALL clutches & flywheels require "breaking them in" periods but if I were you, I would rather be safe than sorry, so your first 400 to 500 miles you wanna drive it, but nothing crazy. Whatever you do, don't go cheap on your fluids. (clutch reservoir & transmission).

^^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.

Thank you for the heads up and tips man! I do believe I read something about breaking it in for the first 500 miles. I think I'll do it for longer though and as for fluids I'm always putting in royal purple for all fluids- engine oil, transmission and differential

Here is how the sprung disk looked after it was pulled. I have never seen a plate grenade like that, no matter how hard I beat on one auto-x'ing.

Im a mobil 1 fan, although, for the clutch I used the Motul RBF600 and for the transmission I used Redline (its expensive as sh1t) but I used that for the first time, Joe from Zspeed said it basically fends off the chatter known for clutch upgrades.

Oh! So you would recommend I use redline over royal? How's that Motul btw I see a lot of people using 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.

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.

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.

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.
