I think that this is the flywheel that i'm going to get. It has all the good qualities of a lightweight flywheel and the driveability seems to be better than the other ones ive seen. Ive also been looking for a decent clutch, dont need a 1000 dollar clutch I dont launch to often but do go to the track once every couple of months. was wondering what everyone has and if this is a good stage 1 replacement? Im not cheap but dont need the top shelf products either.

unless you're a special, it's not anymore difficult to drive, launch, etc your Z with a lightweight flywheel. great mod, wakes up the car so to speak.

for the record I have a 16lb jwt flywheel on my Z for the past 2+ years, 20k+ miles

Lightweight flywheels are great mods that provide better engine response and keep your engine revving in the power band. They're a bit loud when idling though. Totally worth it.

Srm?
 

I looked up SRM: Standard Reluctance Motor (that was a joke btw). Is that what you guys are talking about?

I'm thinkin maybe not...

Thanks Drex: Ya the SRM does react pretty quickly, but is a good question to ask.


Also, someone asked about torque and a lighter flywheel. Starting from a stop will be slightly less torque from drivetrain (less inertia from flywheel to help you get rolling and slightly more torque (to drive shaft) when accelerating (less inertia to spin up). I've always thought the flywheel felt too massive in this car. I guess they wanted it to be easier for mommy to get it rolling.

SRM = SynchroRev Match

I just looked this up and it reads 19lb:

ZSpeed Performance South Bend Clutch DXD Black Nissan Infiniti Flywheel

Yep, I bought mine a couple years ago and it weighed in at 22lbs, but listed on their website at 24lbs. Joe from Zspeed told me that they have been working on trying to shed even more weight from these. I guess they've succeeded.

I'm going with Specialty Z clutch/flywheel combo as next mod.

Wana get the wheels/tires done before or after... but those two are at top of the list.

Flywheel install
 

Don't know if I wanna put the flywheel in myself. How much does a shop typically charge to do that?

I'd say $500 is a good estimate.

I wouldn't consider the install to be too difficult. The only place I ran into issues was putting the trans back on the car. It didn't want to just slide into place, like I had read. I had to get it as close as I could and then pull it in with the bolts.

It is a tedious install though. Removing the shifter and wiring harness before even being able to pull the trans just adds to the workload. Plus, the bolts can be hard to access.

Thanks Aszyd, good to know.
