So I have to replace input shaft bearing on my vx trans...

So while it's apart I'm going to do Clutch, input shaft bearing gear/syncro inspection and re seal. I know the VX has a lighter flywheel then most (CX is NEXT lightest I think) but someone on HT weighed a flywheel at 15.9 lbs.

Now that im replacing it... I have a brand new Stock replacement level Exedy clutch and flywheel. Flywheel is lightened (have yet to weigh)..

Would it be better to use stock or lighter...

Lighter has the effect of losing torque
lightweight flywheel doesn't decrease torque, but it does decrease inertia, meaning more torque will be needed to to accelerate a vehicle off the line ( daily driving).


So I'm hypothesizing a tiny drop in City mile per gallon with a tiny increasing highway so it kind of depends on the driving... thank you.
