Fidanza positives and negatives.

Mine chatters like mad.

Im running a Unorthodox Alum FW, 6 puck unsprung disc, and an aluminum drive shaft.

If you don't give it some gas, and try and drive it like a stock clutch, the damn thing chatters like mad.

Chatter is hueg with my setup. I was commenting on noise from vibrations or whatever.

But yea, my spec flywheel/clutch and an Al driveshaft makes my dad freak out every time I start to drive without giving it any gas. (backing out of a parking spot for example.) I just have to tell him its normal.

The "Chatter" isn't from the LW Flywheel it's from Clutch Discs with no Marcels (wavey spring steel things in between the friction surfaces)

I had an ACT Street Kit in mine that chattered on a stock flywheel, used the same pressure plate on the Unorthadox Flywheel but with Marcel Discs and no chatter!

(The Marcel's purpose in life is to cushion the engagement and stop chatter)

Yes trying to back up nice and slow with no throttle is chatter heaven.

I have used a fidanza in my dsm and didn't have one problem.

In my supra as ideal mentioned i had the stocker taken down from 28lbs (i think) to 11lbs. I honestly think that having a lightened flywheel helps more than some realize. My cars have always reved fast and they are enjoyable to drive without too much difficulity. Lately my clutch has been a little bitch but i'm also using a 3 puck with the 11lb flywheel. I do get chatter when i do not use the gas and the clutch at the right time. I really could not beat the price of $60 to have my stocker taken down to 11lbs. Its not aluminum and can be resurfaced.

my fidanza aluminum FW has a replacable friction surface, so the ability to have it turned is not an issue...

i've got a CM stage III, along with the fidanza al. FW, and i get no chatter. then again, i do have a full clutch disk, carbon/kevlar. it's very friendly.

With my findenza and HPF bronze spung 6 puck you had better rev over 1500 rpm or so to start from a dead stop. It is a quick start and you will bark the tires some but less rpm and it will chatter.

Reverse is a noisy attention getter. I try to park uphill if i will need to back up or just pull thru to the opposite parking space.

I bought mine about 2 years ago and it was a snug fit onto the flywheel. I do like it.

psifactor:
regarding lightening the stock flywheel...
I assume that is just a matter of taking it to a machine shop?
in the sense that they would have whatever tools required to get the job done right?
<in terms of balancing/etc>

over half the wieght gone...
not too shabby.

Exactly.

I noticed the idle speed is alot more touchy and prone to oscilate on a car with a Fidanza (currently tuning the AEM in one) than mine with the stocker. I can't tell the difference at all when driving them.

 

[lagged]

ive got a sprung hub ceramic 6 puck, it chatters but only if you let it!

its very easy to get used to.

I have a friend who has a machine shop. yes he had the proper tools to balance and machine it. You could try a local machine shop and see if they would be willing to do the same for you.

thanks Psi...
I was pretty sure that the balancing portion of this process wouldnt invovle anything a decent machine shop would have, but was just makin sure.
thanks!

chatter what is chatter exactuly is it when you start from a stop and your car shakes untill it hits a higher rpm, also what causes chatter?

I've used a Fidanza flywheel for about 3 years now. (Almost two of which the car was down, but that's another subject.)

RPS sprung 6 puck with 3 sintered bronze and 3 "carbonite" pucks. Also I have the RPS pressure plate

First 500 miles were heaven and hell. Engine/Turbo spools up like never before. Shifts nice and easy, the lighter clutch disk actually cured my lousy 2and shift problem. (Old transmission.)
Hell shows up when you want to drive like a sane person. (Why do that anway?) It chatters, it bucks, it's dang loud backing up, and worse if there is any incline to the backing up. (Like into your driveway/garage for example.) All my neighbors think my car is broken. Piston slap when it's cold, and the constant clutch chatter when I back my car into the garage every time I drive it.

I think a one piece driveline makes it worse too. (Less slack to be taken up.)

Mine fit fine. I do reccomend new bolts however, and loctite.

BTW, you know it only chatters when your trying to slip it right? If you just drop it, it bites, and you either move, or spin your wheels..... Or a little of both. I've found a nice blip of the throttle, then engage the clutch makes for the least amount of drama on launches, and then roll into the throttle as the car starts to move and your hooked up. (Same with drag racing actually, no burnout, just blip it to about 3500rpm, then as the engine is slowing down, let out the clutch, and nail the throttle as it hooks up. Just avoid blowing off the tires with the full WOT hit untill your into 4th gear, about 85/90% throttle at first is all it will take w/o turning your tires into dust. (You get to full throttle, just not all at once.)

At least it's how my car drives. Too much throttle, and it's just tire spin. To little and it boggs. High rpm clutch dumps just upset the car more, and lower my ET's. (I'm not slipping the clutch, I'm just modulating the throttle to use the "large" word out of the drag racing thread before.) LOL
