For street driving I really liked the Competition Stage 2 clutch holds up well to abuse and petal feel is still comfortable to use on the street as well as the track. I had the Competition Stage 2 and Stage 3 clutch kits they are both excellent choices for a clutch set up on a Z. Your CSC will fail it is more of a matter of when will it fail than if it will fail. The CMC is also prone to failure on our Z’s it will fail sometime down the line. Install the Z Speed Performance CMAK as soon as possible don’t wait until you have to call for a flat bed tow truck like I had to. Also the RJM Performance petal and CMC was one of the best and first mods I ever did besides the Z Speed Performance CMAK. The driver mod always helps with a manual Z.

Yeah I was actually looking into the Competition Clutch Kits. I was hesitant about Stage 3 just because my friend has a Stage 4 on his Cobra and I'm like HOLY F***. The car will be NA for maybe all its life, just will do my entire exhaust setup, CAI and Tune but that's about it so not CRAZY power being put down but I think Stage 3 will be okay. I looked on the Competition Clutch website and it doesn't come with a flywheel, which flywheel did you use? Also was it a puck clutch or regular disk? And is it truly needed to upgrade the Master Cylinder? I know the Slave has to be replaced. ALSO after upgrading your clutch did you still keep the RJM Pedal? A handful of questions haha

I used the Modern Automotive Performance lightweight billet steel ST flywheel part#2-630-6ST with both the Competition Stage 2 and Stage 3 clutch kits. The Competition Stage 2 clutch uses a sprung hub design with brass plus and the Stage 3 uses a sprung hub design segmented ceramic. Use the clutch disc that best matches it’s intended use. I had two Genuine Nissan OEM clutch master cylinders not only fail but,leaked and only got worst over time. I highly recommend installing the RJM Performance CMC it will save you in the future because eventually it will fail down the road. I kept the RJM Performance petal with the Competition clutch and I adjusted it as needed definitely a good idea. Also I believe the Z Speed Performance CMAK is the best option to go with. If you do install a Competition clutch kit make sure you follow the 500 mile break in period it is necessary for this clutch kit so your new clutch breaks in properly. Overall the Competition clutch kits were my favorite.

Yeah I was going to do the 500 mile break in regardless of which clutch I get I don't care if they tell me I don't have too, nope lol gonna do it. Anyway I feel like Stage 3 will be alright, which CMC? The HD Premium Tilton Master Cylinder? I'm on their site now that's what I see not sure if that's the one youre speaking of?

Z Speed Performance heavy duty CMC would be my first choice. Also use Motul RBF 600 brake fluid.

Yeah I spoke to Joe he recommended the EZ-Street Stage 2 Clutch Kit. Not bad honestly.

This! I recently talked with Joe and he was great in answering my questions and helping me to select the right clutch for what I plan to do with the car. I went with the Stage 2 EZ-Street kit with CMAK. I just had it installed last week, but have been really happy with it so far. It is noticeably firmer and a little noisier than the stock setup and better in every way. I, personally, wouldn't want it any firmer for a NA DD. I have hated the stock clutch from day one and this is infinitely better. The engagement window feels much improved to me and it revs much quicker and smoother. I do have the RJM pedal/Tilton CMC, but haven't installed it yet. I can only imagine this will get even better.

If you do decide to get a new clutch, you definitely want to address the CSC at the same time. You can save a little coin by going with the HD CSC or, better yet, just get the CMAK. It is also a good idea to replace the stock CMC, particularly if the fluid has become contaminated due to a bad CSC, but YMMV. You can also upgrade the pilot bushing to the Nismo bearing for cheap while at it. Oh, and of course the clutch and transmission fluids.

Hope this helps!

Who is Joe that we speak of? I'm new to the forum lol. Anyway, yes the stock clutch is booty, catch point way to high, overall booty. I may get the Competition Clutch Stage 3 maybe but I'm wondering which brand Slave Cylinder and Master to use.. CMAK is a slave deletion? Huh? Lol I just searched it and that's what the description was :/. I'm sure the clutch kit I'll get should have the throw out bearing along with it hopefully. I gotta see how the pedal feels after installing the clutch. Which fluid did you use? Theres a few out there.

You're basically stuck with 1 of 4 solutions for the CSC.

1) CMAK (clutch movement alteration kit) actually moves the slave cylinder outside the transmission bell housing.

2) HD CSC is an upgraded version of the slave cylinder using metal components as opposed to plastic.

3) Z1 CSC Delete is a kit that actually eliminates the slave cylinder entirely, down side being it requires periodic adjustment over the life of the clutch.

4) OEM CSC is just asking for pain, since it'll go again at some point, but is the cheapest option up front.

I personally went with the CMAK. It works great, and no complaints so far. Joe is Joe Allison from Zspeed Performance. He's a good guy and great resource for all your clutch related questions.

Yeah it seems like CMAK is a popular upgrade. Which site did you get the CMAK off of? ZSPEED?
