Default clutch and flywheel

In a couple of months, my clutch will probably be fried it's slipping now sometimes.
When im in the market for clutch and flywheel, i'm thinking about lightest ones out there. Looking at under $600 for clutch kit and flywheel.
ACT prolight is slightly lighter than JWT flywheel. Is there one lighter and stronger than ACT prolight? i heard competition clutch is the LIGHTEST one out there but can't find the exact weight.
The car is used for DD, autox and drift. I wish there's one close to Tilton which weighs like 8lbs. (sucks it's out of market now)
Light flywheel (under 13 lbs) AND clutch with smaller in diameter than stock would be really nice.

I can't reduce much weight on the car such as stripping the interior or buying expensive light parts. So reducing weight on rotational parts, clutch and flywheel, would be easy and give good amount of accel.
i always thought that stock ones rev up really slow and not instantaneous.

The way I understand it is that DM flywheel rev slower, but are easier to get going in 1st due to the intertia. The lighter you go, the more reving is required at start. Not that it's necessarily a problem, but it might be an inconvenience you may not want, especially if you're looking for the lightest possible flywheel. My suggestion is try a heavier lightweight, since it'll be a DD. Good luck with your decision.

i understand that i have to rev higher to start moving. i usually rev at 1500 RPM or under to get it moving lol. it's something i gotta change.
what do you mean by heavier lightweight? i'm more looking for super light lightweight flywheel haha

the flywheel also keeps the car running and firing plugs.
The only real benefit of the super light flywheels are for making cool youtube videos that make your Z sound like a GSX-R.


Imagine a small motor cranking a bike pedal around smoothly with the bike on its side... and that bike has a card in its spokes.. think of the sound. Steady, monotone etc...

Imagine the sound of someone cranking that bike pedal by hand... its not linear, it has more ups n downs. Its jerky.
Thats how your car will run with a ultralightweight flywheel.

You have to rev it high, then expect it to drop very fast as well almost bogging. If you daily drive, you will absolutley hate yourself. And youl burn clutches w it. it wont hold heat as well either.
You want it heavy enuff to allow the car to run smoothly, but light enough to allow better power xfer to the driveline..

what the other guy meant is you really WANT a heavier lightweight flyweel like a southbend or a JWT.
Anything that isnt stock, heavy or not.. will chatter. (Noise)

thanks for your replies. i could maybe go JWT if it was little cheaper.. and i don't like the fact that everyone is using JWT combo lol. i always seek for something different

1 lbs or 2lbs lighter than JWT lightweight flywheel would work. Maybe little smaller in diameter along with the clutch kit. heard cerametallic is indestructible gotta have this chit

everyone uses it becuase the clutch is one of those things that can create a nightmare if its not matched well or doesnt fit right, so ppl stick w what works.

You'll also find yourself on the gas more. Like when you're on the freeway and you let your foot off the gas, even though you gradually start to slow down you still retain a fairly strong forward momentum and find yourself being able to coast for a bit. With a lightweight flywheel, you'll lose this ability. As soon as you let off the gas you'll slow down much faster, and you'll find yourself always on the throttle to keep it moving.

This could get really annoying, imo!

Then again I do love the sound and response to a fast revving motor

Just get a full JWT combo , works great for street and track . Also the flywheel has an easily swappable plate on it for when you fry the clutch. I'm not a drifter, but track my car. I have almost 100k on my JWT and its slowly giving up.

that is really a stupid reason to not want something mechanical. aesthetics, sure, be different, but if something works, and works well, and everyone uses it, who cares? no ones going to know what clutch or flywheel you are running but you.

I wonder who you're talking to that is giving you all this priceless info, such as comp. clutch's flywheel being the lightest, or that cerametallic being indestructible

what you want, at your intended price, doesn't exist, unless you're buying used parts

Those priceless info were somewhere in this forum lol

like I said, what you posted that you want, at that price point, does not exist unless you buy it used
