i have 31,xxx miles on my 07 z. had the slave cylinder replaced by the dealership the first time bc it was still under warranty or recall or whatever. then i had the JWT clutch and flywheel installed. slave cylinder went out 2 more times. friday it just went out again and i am so bummed and frustrated. especially since i dont track it or stomp on it that often and the miles are low. had it towed to a shop. was thinking about getting the zspeed replacement parts if the shop would even install it but im not so confident. i dont really know what other options i have bc obviously just paying to have the same failure part on again seems stupid after this many times. this couldnt come at a worse time money wise but i need my car and i need it to not break. its stressin me out so if anybody has any advise id appreciate it. thanks.

 

Definitely go with the zspeed hd slave, I've has one since it came out years ago, one of my favorite mods for sure, granted I never had issues with the stock one but felt as if it was a gamble at times esp at the track.
The willwood master is amazing too, if you have the extra money ($160ish I believe) get that too.

 

its good to hear u havent had problems..this oem crap is not holding up i just cant believe how fast it goes out..how many miles do you have with ur hd slave and master?

 

I've got the ZSpeed HD upgrade as well on a mid 600 whp Z. No issues at all. My OEM unit went out on me at the track once and I had is replaced under recall.

 

ok awesome hopefully the shop where my z is stuck at can put the zspeed parts on...im kinda jealous of over 600whp.. jesus i wonder what that feels like..couldnt you have got a gtr for the price of that build?

 

zspeed HD CSC is only solution to fhe crappy oem plastic unit. I got my z used and two weeks later i was dropping the transmission to change out the CSC.

 

You should have went with the HD CSC when you did the JWT clutch in the first place. Its well known that the oem one will not last with a aftermarket clutch. I doesn't matter if you beat on the car or drive it like grandma.....The force required to engage/disengage the heavier clutch destroys the oem CSC regardless. Always wanna to it once the right way rather than doing it 4 times the wrong way.

 

I never had any issues with my Oem slave. But I am ordering an act clutch combo this week so will be upgrading to the zspeed unit as well.

 

I had a spec stage 1 clutch and RJM clutch pedal on the OEM slave for about 15k. Finally went out about a month ago. Upgrading to the HD slave and Master with all new stainless lines in the spring. OEM slaves are junk, idk what Nissan was thinking...

 

Yes...with a few nice aftermarket parts.

 

I am using the Zspeed CSC and Willwood Master as well...

 

alllllright thanks everybody i ordered that shitte today so hopefully after it goes on i wont b back complaining in a year about my damn transmission
