Lightweight flywheel with stock clutch?

atx370z

Going with the 4.08 gears and want to have a JWT lightweight flywheel installed at the same time.

Is it necessary to upgrade the clutch? Or is the stock clutch sufficient for a mild N/A setup?

I have the standard boltons... G3 intakes, Berk HFC's, exhaust, Uprev tuned.

Going with gears and lightweight flywheel to achieve a high to mid 12 second N/A car. Then, i will be happy.

I'm just concerned if i upgrade the clutch, i will have to upgrade the CSC also. Seems like unnecessary spending if i don't need to upgrade the stock clutch.

I had a JWT flywheel installed earlier this year. My Z had about 25k miles already, maybe 100+ 1/4 mile track passes already. I was lucky and managed to find a low low mile stock clutch and had it installed with the JWT flywheel for cheap insurance.

Jnaut did the install and said my stock clutch looked pretty decent. There was some wear on the clutch disc but nothing major.

I went with a stock clutch to avoid any problems with the master cylinder & CSC. I wish the stock clutch had more clamping force, but right now its better than dealing with the other hydraulic problems.

don't bother with the clutch unless you go to the drag strip or plan on boosting.

Awesome, thanks!

I might go to the drag strip a few times, but not regularly.

Just saved myself a ton of money. I was about to buy flywheel, clutch, csc, etc....

I've seen enough people down here replace their clutch. Then the CSC. Then the master cylinder. All in a short period of time.

Clutches can be replaced with aftermarket ones. CSC can be replaced with aftermarket ones. Master cylinder, I haven't heard of any upgrades.
