Thinkin about picking one of these up with my new act street clutch. What is your experience with these flywheels? Are they durable? Is it that much harder to launch? Do you lose any driveability with these? Can these be resurfaced? Thanks in advance for any input.

 

I bought one to go with my ACT HDSS disk, but neither are installed yet. I feel like I did more than my share of homework, though, and I haven't run across any negative testimonies concerning the Fidanza. Very durable, and only 10.5 lbs I believe. That might translate into a little throttle blipping, but nothing I consider a detriment.

Sorry, I'm not really any help!

 

I have an unsprung ACT 6 puck and a fidanza flywheel.. And I love it! It took me a couple days to get used to but going from a toasted clutch to a 6 puck was tricky enough.. The only downfall for this set up is you cant really drive a steady 3mph through parking lots or the car will "buck" .. Rpm's drop really nicely between shifts.. I flat foot shift and I have never hit my rev limiter

 

Are the fidanza flywheels aluminum???? Just curious cause I heard aluminum flywheels warp alot easier then the cast or billet iron ones. Just food for thought.

I personally went w/ the ACT XACT Prolite flywheel and love it. If you just wanna know about driveability w/ a lightened flywheel I havent had any issues. Launching is just as easy w/ it and it seems to free rev quicker when two-stepping.

 

Fidanza is quality stuff, the stock flywheel is already pretty light though, so theres probly a little to be gained but it's not going to be huge.

 

I have an ACT hdss with the prolight flywheel (10.1lbs) and its great. No launching problems,any kind of driveability problems at all. Smooth as glass from a slow ez start to a high rpm launch.(if done right of course)

 

I have seen a few cases where the Fidanza has lost its ring gear. Something due to the expansion of the metals.

 

Fidanza makes great flywheels. Aluminum all the way!

 

I would recommend the Exedy flywheel over the Fidanza. I have seen both. One was a Fidanza I replaced with a Exedy.

 

I love fidanza, you never have to resurface it, just replace the friction ring for like $60, and it's a new flywheel again.

 

A forged 1 piece flywheel > 3 piece aluminum flywheel. Separate steel friction surface, separate ring gear and aluminum flywheel. In addition it can't be resurfaced, so you need to to keep buying the steel friction inserts if they become warped. Aluminum is also not very stable and can expand and contract depending on heat, which is not a great characteristic for a flywheel.
