What is everyone's opinion on lightweight flywheels?

[Shane@DBPerformance]

They do next to nothing for power, especially on a dyno where you usually run in 4th gear. They are required for safety reasons once you start making a lot of power. They help road racer guys rev match a lot quicker because the rev up and rev down much quicker when you are out of gear.

I have a fidanza, and none of the issues you guys describe. I like it.

Same here.

They are not that expensive Peter. I believe I bought mine for somewhere around 220 or so off ebay. Not sure if shipping was included or not.

well I wouldn't run one just because I saw what happen with Speedfreaks car... The bolt's being ripped right out of the flywheel... thats not cool. Yes he was running what a 3100 or 2900 I cant remember off the top of my head, but still it ripped them right out..

That was because the throwout bearing went to pieces and destroyed everything in the area. If you plan on making a lot of power, you better run something. It would even less cool to have a stock flywheel come apart at 9000RPMs and come through your hood.

Yea they are not that bad as far as price goes. Just didnt know you needed a non stock one when you make it up there in HP. Although, everything adds up as far as I see it, thats what I meant as far as price goes.

Im going to be taking my tranny off again to replace my clutch since that is what I think is the problem... pressure plate lost its tension making the clutch engage very very low.

Is it worth it to buy a diff flywheel while im in there? Or should I just skip it and get a FPR or springs/camber kit instead? Those are my options for this summer.

Main reason I have it. And when you take into account the fact that buying it saves you $35-45 on getting your flywheel machined, (the first time you put it in) it looks a bit less expensive.

I have a twinn disc clutch with intergrated flywheel. The whole assembly weights less than 14lbs. It revs like a crotch rocket, but its gonna take a bit of tuning to get it to not die when i push the clutch. Overall though I really like it

Well, it sounds like there's an even mix of opinions from everyone. From what I'm gathering, it seems like it'd be a wise choice to just keep the Fidanza I am using and work on tuning and adjusting things to keep it from stalling. My question is what things would I need to look into changing? Is there much that can really be done or is this a problem with the ecu where the engine is decellerating faster than it thinks it should be?

To answer Jakey's question I do have an eprom ecu with all of the goodies but no change to the idle speed.

so fidanzas are already stepped right out of the box? for ACT or what depth?
