Drivability and quiet. The extra weight of the OEM dual mass makes it easier to drive, specifically from a stop and has a urethane dampener that keeps it from chattering.

I know what they were thinking it would accomplish, but my EXEDY kit is significantly easier to drive, and it's got a solid flywheel that's 10 lbs. lighter. It doesn't have that weird over-center feel pressing and releasing the pedal, and feathers out smoothly even when I'm half-assing it expecting a little bit of bucking. I admit the pedal feel was likely partly due to wear, but like I noted in my earlier post, I (personally) don't feel any need to install an RJM pedal with the EXEDY kit as it functions now.

The only increase in noise is the tiniest bit of rattle when sitting at idle from the bouncing clutch fingers. You can hear it running the car next to a wall, such as pulling through a drive-through. It's got close to zero chatter, and I'd be so bold as to say less than the stock (maybe stock replacement) clutch that was in there before.

When I had my previous G37 I had them install a solid nodular flywheel from Z1 and a new stock replacement clutch. It rattled badly enough that I thought something was wrong at first, and then later found just life with these cars. Point is, if a specialty company like EXEDY can built a street clutch set that performs better in very way while remaining very easy to drive and stay quiet, I have no idea why a company like Nissan with millions in R&D could not.

Mine sounds like a diesel idle:roflpuke2: but the 19 or 20 models are now coming with an Exedy clutch. I don't know how deep the changes go, so not sure if the flywheels are any lighter or different in any way, though.

That's exactly what the clutch in my previous G sounded like. :icon17:

Hello, everyone. I didn't want to create a new thread (reducing clutter) so I'm asking here.

I'm looking for a good 10 to 12lb flywheel for my 2015 370z. Noise is no issue, I've been looking many places for one and can't seem to find one.

The only one I found is this, but I'm not even sure if it fits, nor the quality...
Competition Clutch: Forged Single Mass Flywheel

I heard about a South Bend stage 3 flywheel that weighs 12 lbs but I can't find any actual part for it (only a review).

Any help would be godly :icon17:

here is 1 for u. https://www.z1motorsports.com/clutch...6.html:tiphat:

How's the chatter at idle? Thanks

What was your lead time in ordering the hardware? I'm stuck in the same situation with a bad CSC & clutch, and the recommendation is to swap out the flywheel as well. Problem is that I've looked at Z1, ZSpeed and a couple others but everybody is on back order. Meanwhile my car is sitting in a shop with a mechanic waiting on a decision. I'll be damned if I'm going to pay a grand for an OEM flywheel and another 1050 for a OEM clutch.

I haven't ordered it yet so I can't provide a lead time. However, I'm certain I'll be purchasing the ZSpeed kit based on all the reviews I've been reading.

I specifically did not buy the "quiet disc" clutch package from Joe and asked for a light flywheel (ended up at 17lbs). I am disappointed that my clutch does not chatter at all :twocents:

:rofl2:

No chatter at idle. Sometimes a little chatter slipping into 1st, but barely noticeable. It operates EXACTLY like I prefer, and the operation is a thousand times more precise than OEM.
