New Clutch help pls...
 

I'm looking to replace my OEM clutch which is starting to slip a bit.

Vehicle

• 2011 370z
• 80000 miles
• OEM power

I am looking at two different CSC elim kits.

• Z1 CSC Elimination Kit
• ZSpeed CMAK Elimination Kit

Pros and cons of either?

Where is the option to vote against posting the same poll in multiple subforums?

Sorry, can't delete the other. Sheesh

I put my CMAK in myself. It's a really good set up. No special adjustments. Very linear clutch feel

If and when, I'll probably go CMAK. No dust boot kinda blows though.

I am planning to go CMAK for being auto adjusted by the life of the clutch. So this is my choice.

Cmak no adjusting did the install myself work flawlessly

My b! I was ornery early today.

ZSpeed Performance CMAK Elim kit

The Z1 kit isn't all that great. They say "may require adjustment through the life of the clutch" when it should read "requires frequent adjustment". In 4k miles with ~400miles on the track I had to have it adjusted 4 times and replace the slave cylinder once. Z1 says that's normal for track usage. The not so funny thing is the OEM CSC held up better.

I have to adjust my Z1 kit about every 10K street miles. The first cylinder (I was pretty early adopter) failed within 2K miles - they sent me a new one at no charge. The 2nd one failed after about 25K miles. The 3rd one I'm on now is almost to 20K miles and is starting to squeak, which seems to be a sign of impending failure based on my previous experiences.

I expect I'll need to replace the clutch in the next 25K miles or so, and I will definitely be going with the ZSpeed CMAK.

CMAK. All the way.

I prefer the stock Z Speed replacement HD CSC. Its a sturdy design and it works.

Matched up with a good clutch/pressure plate and semi lightened flywheel, it will last forever. But that depends on your future plans with the car.

:iagree:

Why deviate so far from the OEM design just so you can service a part that is known to be reliable?

I would purchase none of the above. My favorite clutch combo was the Centerforce Dual Friction Clutch and Stillen flywheel. Overall petal pressure was just alittle heavier than stock and it took all abuse I gave it from street driving to the track and it still held up fine.

What slave cylinder are you running though? That is really more of the concern with this post...

Also CMAK ftw
