ZSpeed Stage 3 Super Street High Power Clutch Kit Choose Options 370Z G37 G35S

First and foremost, just want to say thanks to George who has been quick to respond to my queries before the sale, after delivery and after my install. I'm an international customer with a RHD Z34. A few years ago, Zspeed didn't ship overseas. For all you international Z owners trying to get your hands on a CMAK kit, you can now buy directly from here. I bought the Zspeed Stage 3 package with the CMAK and lightweight flywheel, along with extra goodies like bolts, a spare slave cylinder, and spare throw-out bearing. The instructions were well-written and very accurate. I encountered only one problem which was the guide tube of the spare throw-out bearing not sitting flush with its back plate. George will be sending out a replacement to me soon. The CMAK fitted very well and felt bulletproof. Nissan should have done something like this from the beginning. If you're new to lightweight flywheels, when you switch from the factory dual mass flywheel, the first "concerning" change you'll notice is the chatter at idle, shuddering at the engagement point if you're at idle rpm, and more chatter if you're lugging in too high a gear at between 1500-2300rpm. I use the word "concerning" because NVH is subjective to the individual and their previous exposure to different cars/clutches. Nobody really explains the intensity of the noise and vibrations you feel. For me, coming from the factory DMF with the sprung pressure plate and sprung disc, it was night and day difference. At idle rpm, if you bring it to the biting point and hold it there till it just starts to move, the car shudders quite badly. I soon figured that this is because the factory DMF is weighted to provide that inertia so it "resists" stalling as you move off. And it also acts as a harmonic balancer to cancel out the vibrations and pulses of the engine. With the lighter flywheel, it doesn't have that inertia and comes to the point of wanting to stall, hence the shudders. To move off smoothly, all you have to do is give it a bit of gas. Those who are able to adjust your idle rpm, I believe raising it to about 900rpm would be the sweet spot. Once it engages, oh my! It does so with great urgency and positivity from a narrower engagement window, unlike the spongey wider window of the factory clutch. The disc itself is an Exedy organic with copper strands and is about 10mm larger in diameter. The combination of the more aggressive engagement with the lighter flywheel makes acceleration feel better. Rev matching is also much more quicker. Pedal effort feels like 50-70% harder than factory, while engagement point is about the same as factory which is about 70-80% off the floor. Overall, this combo feels like a no-nonsense setup that is suitable for daily driving yet capable of high HP. It's nowhere as harsh as a ceramic disc but you will have to accept some drivetrain chatter.

Ordered the entire kit with CMAK. Buddy had done numerous installs and it was running swapped in 4 hours. Pedal is definitely firmer but it doesn't feel like a knee killer. It's a business clutch now on firmness but very street friendly still. 10/10 already recommended. Stock power but I intend to change that. G37

By far the best setup iv felt in a vq imo. If your looking for easy accessibility and maintenance I recommend going with the cmak v3 kit as I did. The next thing is the flywheel. I think the 19lb mid weight is the perfect happy medium. Very subtle chatter, but just the right amount of responsiveness you want with reving faster. Lastly the clutch its self is awesome. Id says its about 2-3 times heavier than stock, but I personally love it. The initial bit of the clutch point makes it so easy off the line especially with the weight of it. Overall very impressed even with customer service Joe is awesome and very quick to answer your questions.

Amazing product

Everything was fairly easy to install and works great so far, still in the break-in period as of now. Clutch feels a little different - pedal requires a little more effort but still pretty close to stock feel. I'm very happy with the whole package.
