I have an 05 and just purchased a dual fricton Centerforce clutch, and I am thinking about purchasing a fidanza flywheel along with it. What do you guys think, is it worth another 500 bucks for a 19 pound flywheel? What are the pros and cons? Any feedback would be appreciated.

I believe the lighter flywheel really does make a good addition to the Viper. It does not need the weight of the flywheel to get off the line it has TORQUE! The lighter flywheel will also make changing gears up and down smoother. Will rev noticibly faster also.
i have the RPS from PartsRack Online Shopping - Home the RPS comes balanced from the factory and will not need any more work the Fidanza may or may not. i really like the light flywheel on my car. with the added bonus of loosing 19 lbs
I have been told that adding a lighter flywheel makes the car leap forward at lower rpm speeds, not sure how true it is, and if it was just a one time ordeal for the guy.

Not quite true. It allows the engine to rev easier, but not enough to cause your car to leap forward.
A heavier flywheel will cause the car to leap forward off the line if you dropped the clutch. The reason being the extra weight has more momentum which translates into a greater push off the line when you drop the clutch.

I do not believe this is what he is refering to. I am fairly sure he is talking about low speed surging, which is aggravated by lighter flywheels. The surging is normally absorbed by the flywheel (for the most part). When you switch to a flywheel that has a substantially lower MMOI- Mass Moment of Inertia (Weight actually means nothing) the surging from the engine is not absorbed, but rather transmitted to the drivetrain, making the car "leap" and "buck". You should be OK as long as you have at least 75% of the MMOI of the OEM flywheel and clutch (for street use). Also dont forgot, the pressure plate accounts for about 35-40% of the overall MMOI of the assembly. I will have the exact numbers soon, as we are waiting for our new flywheel design to hit production.
From my experience, aluminum flywheels are generally fine. You may have to adjust your driving style some, but nothing you cant change in a day of practice. The problems start occuring when you are using light flywheels AND light clutch assemblies... making it overall <75% of stock MMOI. I actually have a Tilton setup on my car for testing that is about 10-15% of the MMOI of stock, and while the clutch itself is GREAT, it needs a MUCH higher MMOI to be fully streetable. Glad its only temporary... problem solution en route.

let me know final gts, as a little lighter rotating mass is always a plus. the guy who told me this works on dozens of vipers here in PHX, so he wouldnt BS me on this.
