Opinions on flywheel needed.

[SlowSpyder]

A bit of a delima here. The short version is that I ordered a Fidenza aluminum flywheel from Competition Clutch. They accidently sent me an AWD flywheel. After getting everything sorted out, and the AWD one shipped back, they told me that they no longer carry the 8lb aluminum Fidenza flywheel for FWD. They do however carry a 12lb steel flywheel, but are out of stock (more expected in a 2 weeks). Obviously this is lighter then stock, but still not Fidenza light. So, if you were in my shoes, would you go with a refund and get an aluminum from another vendor, or should I just get the 12lb steel? With the 4lb lighter flywheel, are there any real benefits to be had do you think? Or would I actually like the extra wieght for a street car (not a daily driver, but a weekend street car)? Opinions, two pennies, personal experience, and b.s. welcome.

I'm leaning towards getting a refund and getting the Fidenza or ACT aluminum flywheel, but if the 12lb steel is just as good let me know. The decision is hardly set in stone, that's why I'm asking. 8-)

id just get the ACT flywheel stock ligthened flywheels equal this...

I would go for the money back and pick up a Fidanza. I have had great luck with the fidanza, and the replacement friction disks are pretty cheap and reliable if you are using a street disk.

I have the 2G AWD fidanza with an ACT 2600 Pressure Plate and a Horsepowerfreaks.com kevlar full face sprung disk. Nearly 20,000 miles on the disk with great wear characteristics, and no bowling of the friction plate on the flywheel. This is a street/strip car with 100+ passes on this setup without failure.

You should be able to pick up a fidanza in stock at most places for around $200.

Good luck,

yeah fidanza is good to.. i have an ACT in my galant. and i have a fidanza sitting here for my new DD..

ill probably endup swaping in a fidanza in the other car nex time it comes out.

both flywheels are good better thing about the fidanza is the $50 replaceable surface. which you can do on a normal flywheel to but you can only do it so many times while the fidanza should last forever :)

[Donny]

I agree with jason.. or get a JUN flywheel it's even lighter yet lol.. i think..

[Arnie]

Jun=garbage. Look on RREs web site. Too thin for any amount of decent launches. Also, arent they 7 bolt only?

[LILEVO]

I'd get the Xact flywheel.

[Arnie]

Can the XACT be resurfaced?

[Jason]

i think i can be maybe once.. other then that i dunno.

[SlowSpyder]

The steel flywheel is not a lightened stock flywheel, it is an aftermarket piece.

I think I'll ask for a refund and go with a Fidenza. I think I paid $175 or so for the flywheel, so if I just get a refund I can pick up a Fidenza with that plus very little out of pocket.

I had a fidanza in the GVR4 and the talon, good flywheel for the price!

[brian]

And you put what, 5 miles on them?
:gai:

You have no relavant input

[Jason]

LOL

[pma1123]

I'll back up the fidanza, good increase in the top end noted upon installation. Rev matching for shifts is effortless after installed.

[Nick A]

Fidanza in the GVR4 for about 3k miles and in the talon for about 1k miles
Great flywheel!

[PHAT TONY]

someone post the prices of these flywheels....i'm sure that will help make a decision as well!

[GRAFH]

are you planning on running a scattershield ?

[Arnie]

Steve's car wont break out of the 14s, what does he need that for? :fruit:

Then again I spose I will have my hand in the install, so maybe it WOULD be a good idea. :beer: :fruit: :woot:

i would recommend a exedy flywheel for the following reasons :

EXEDY Racing Flywheels are made from solid one-piece billet chrome moly steel or chrome moly steel forgings. They are not painted billet steel to look like forgings like our competition. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the air flow to improve the cooling of the clutch. The ring gear teeth are milled onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibilities of separating from the flywheel. This could cause the flywheel to explode due to two different expansion coefficients (aluminum flywheel pressed on steel ring gear). EXEDY steel billet and forged steel flywheels have passed engineering tests to 15,000 rpm. They are guaranteed to be explosion proof at the said rpm.

i believe all the flywheels mentioned in this thread fit this type:
"an aluminum flywheel where the ring gear is pressed onto the flywheel and have the possibilities of separating from the flywheel"

"This could cause the flywheel to explode due to two different expansion coefficients (aluminum flywheel pressed on steel ring gear)"

[Arnie]

Do you work for exedy? Nice cut n paste. Lets see some real world experience here!

Also, that shit about the flywheel exploding, well, anyone with any knowledge of materials will tell you that aluminum has a higher coefficient of expansion than steel does, so as your aluminum flywheel with a steel ring gear gets hotter, it only gets tighter pressed together, not the other way round. Not only that, but steel is more ductile than aluminum, so the ring gear can expand to take this growth into account.

ACT and Exedy are both made from iron. Fidanzas are aluminum with a steel ring gear and steel friction surface. You could just have easily suggested an ACT flywheel based on your input.

both flywheels are good better thing about the fidanza is the $50 replaceable surface. which you can do on a normal flywheel to but you can only do it so many times while the fidanza should last forever :)

Just a FYI on that.... The price of the replacement surface has jumped considerably. I ended up with a Fidanza for my car as part of a deal to buy a used tranny for my car. The surface wasn't that bad, but had signs of heat issues, so I went looking for the replacement surface. Best price I could find was around $85 shipped. And yes, I checked Road/Race, who still has them listed for $50. They didn't have any more for my flywheel.

When you can buy the whole thing new for ~$190 shipped, the replacement surface isn't necessarily as attractive.

This is bullshit about a pressed on ring gear in the case of the Fidanza. There are also fasteners from the backside of the flywheel that key the ring gear into place, AND firmly bolt it down into the machined recess around the perimeter.
