Flywheel Question

Casenova · 10-07-2010, 04:55 PM

This was probably answered, and maybe I fail at the search feature, but I have read conflicting info about switching out the stock flywheel or not. So..

One: Should you switch out the stock flywheel with a lightweight aftermarket flywheel?

Two: What companies offer flywheels for the 370? I noticed SZ and fidenza (sp), any others?

Third: What do you do about the SZ flywheel/clutch combo problem with it messing up the CSC?

Thanks

Jim Wolf technology makes a nice unit.

Our kits include an upgraded CSC.

The benefit to using a lighter flywheel is quicker revs and engine response along with the side benefit of "freeing" up more power.

Are there any long-term side effects of changing the flywheel? Or does this not affect the engine life at all?

I would say that the cons about lighter flywheel :

1) less momentum on the flywheel, harder to drive in stop and go traffic and simply getting the car to move from stop.
2) correct me if i'm wrong, but you may have to ride the clutch more/longer before it is fully engaged with a lighter flywheel ( that's my experience from driving a EVO9 w/ ACT flywheel)

No ill effects whatsoever to engine life or reliability.

1) Yes this is true, however once you get accustomed to the difference you wouldn't even know any better. The VQ aftermarket flywheels aren't as light as other car makes so it won't be as dramatic.

2) Not necessarily. Alot of it will depend on the friction material (clutch disc) you have and pressure plate release.
