I haven't tracked the car yet, so for now it'd be for driving hard around town and on the freeway. would a 9lb setup be too light for a fairly stock svt?

planin on doin a procharger setup later on. but not sure which flywheel to go with.

It takes getting used to my daily SE with a crate motor 240whp from cfm uses their stage 4 clutch from clutch masters and their lightweight flywheel aswell. just something you have to get the hang of im sure you'll stall every once in awhile but whatever.

what about wearing out quickly. I heard rumors of a really light flywheel wearing out early. and truth to this myth?

Although this can vary with design, aluminum flywheels are more likely to be damaged by heat than a standard weight iron or steel flywheel.

The lower weight/mass of an aluminum flywheel can cause the engine to idle rougher. And for the same reasons, the car will be more likely to stall like FocusBoy stated especially when starting from a stop.

If not made correctly, the starter ring gear on an aluminum flywheel is more likely to become loose.

The mounting bolts on some aluminum flywheels tend to loosen.(Torque the flywheel cold and use locktite)

Your car will accelerate noticeably faster(especially in the lower gears) with an aluminum flywheel.

If the car is everyday transportation and/or you find yourself in long traffic jams, I would not recommend an aluminum flywheel!

Ohh and Most Aluminum flywheels available have a removeable steel friction surface as well- so in theory, could last longer, but in reality, they simply don't wear all that much for most of us to worry about.

I've had a Fidanza Flyweel on my car for about 40k and have had ZERO issues! The car revs way faster and engine deceleration is also improved.

They are right about the flywheel having a removable steel friction plate.
The Fidanza for the SVT is NOT 9 lbs. I weighed it on a certified scale 12.8 lbs. Compared to the 25.6 lbs Stock flywheel.
You will notice gear noise with the flywheel when idling in neutral with the clutch engaged but its not that bad, and if it really bothers you, just press the clutch in, and the noise will go away.
I really recomend it especially if you are going to go FI.
If you can afford it GET IT!!!!

It is always better to get a matching clutch and flywheel. I had a stock clutch and the fidanza and it was much better than the all stock feel.

Correct, the 9lbs is a misprint on the Fidanza website... only teh Zetec (non SVT) gets the 9 lbs flywheel.

Personally I've never heard of anyone "wearing out" a flywheel... with the exception of grinding teeth off of it.

less rotating mass = more torque to the wheels!!!

I would assume that if the fidanza wore out on you then a lot less people would run them. I also never heard of anyone doing anything but losing teeth on one.

Well.... sorta.

The heavier flywheel will cause the engine to produce more low end torque (just to overcome the weight of the flywheel) and it'll cause the torque to carry between shifts.

BUT you get so much faster engine response with the lighter one... its basically a trade off.

lighter flywheels are better for spirited driving like auto cross. the engine revs faster but it also revs down faster. this isnt so good in something like a drag race where your trying to bang thru the gears and get to the other end as fast as possible because when changing gears the engine spins down and more out of the powerband and hasto work harder to get back going in the next gear. if your into just flat out hauling ass it would be better to get a steel billet flywheel.
