I love mine so far with a spec 2+. Wouldnt have done it differently. I was hesitant at first about this piece as well but its chromoly steel thats some strong shet.

I went with the Fidanza Steel Flywheel. Physics plays a huge roll here. Heavier cars do better with heavier flywheels. Steel flywheels get the car moving faster from a stop and from a roll. When your cruising at a constant speed the flywheel is turning a certain RPM (constantly) just like it is when the car is sitting still revved up on the line to whatever rpm you do that. You still have to change the momentum of the car from that constant speed to a greater speed via acceleration. While less noticeble the car/flywheel exibits the same effects moving at a constant speed say 50 or 60 as it does sitting still. The other benefit of a steel flywheel is that your rpms stay up much easier through shifts because of the "an object in motion tends to stay in motion" law. I'm having a difficult time explaining it more clearly. It definately seems more clear in my head than what I'm reading.
A more simple straight forward answer is...look at most of the quickest/fastest Cobras. Most of them are running steel flywheels. A lot of people will say that is at the track but their trapspeeds are higher too which is how a car will run on the street/highway. There is a bunch more to setting up a car to run fast than what will net you the highest dyno number. This will always be a topic of endless debate. Hey, we don't all think alike. Good luck, it is a decision I thought a lot about. The lighter flywheel will net you greater dyno number by about 10-12rwhp. If that is what matters to you; you should get a lighter flywheel.

im staying with steel. When you get stronger clutches that chatter, wait till you match it with a lighter flywheel, then it will really chatter..
man where you right, , i'm using a steel f/w now on a new fidanza 4.3 and for the 15 miles that i had already put in, it doesn't chatter as bad as when i had the fidanza alum f/w, i'm impressed to say the least, i also added a ldc freeplay mod and it doesn't feel as my first 4.3 clutch, (i remember as if it was now when i first drove it off the shop)
A steel flywheel will get you off the line quicker if you have plenty of traction if not your just going to spin the tires more.
It's true that the aluminum f/w will dyno higher 10-20hp. In the lower gears it's more like
20-30 hp .... the lower the gear the greater the hp difference, the higher the gear the difference is smaller.
With a grabby clutch you will have less clutch chatter with a steel flywheel. I have noticed more cars breaking in-put shafts with stiffer clutches.

I have a spec aluminum with a stage 2 clutch. I'm loving it right now. The street maners are just fine and it does rev faster and pull a little harder in the lower gears. It took me about a day or two to adjust to the lighter flywheel.
I have the FRP steel flywheel ,it wieghed 33 LBS on the scale.I noticed an immediate change in street maners. less rpm to get out of the hole,less chatter and less rpm drop from 2nd to 3rd while taking corners at low speeds and traffic manuvers. I would not change back. IMO

i have a spec aluminum flywheel... as said above, an aluminum flywheel will see higher numbers on the dyno both in hp and tq, this is because of less peracetic engergy loss. you will see instant feed back from the gas pedal.
