I read somewhere that it rattles?

hi peterpoop

excuse my english but i can´t understand you ..

I have the Fidanza flywheel. No rattling at all. (where'd you hear that?) The lighter weight frees up rotational inertia to increase responsiveness. It's just like a giant pulley in that respect.

A lot of work just for that though; unless you are doing more like a clutch or LSD at the same time.

thanks cali yaris !!

I read it on a supra forum. Some guy was wanting to sell his supra and said there is a rattle. But he said he as common when running a lightened flywheel on any car.

Oh well!

Definately one day if my clutch ever goes out, I'm forking out the cash for a LSD and lightened flywheel!

It should not rattle if its tight

my fidanza (same as Garms) does not "rattle" (wtf are you reading peterpooop?). and i had to re-learn heel-toe as the revs drop off much faster than stock.

IMO not an investment i'd make again if i was looking for power. it's simply NOT WORTH THE $$$. however, if you're making more power and are installing a better clutch (please no Spec clutches http://www.yarisworld.com/forums/sho...ht=spec+clutch you might as well pick up the Fidanza. even bolted to the Spec stage 3 which is heavier than stock, you drop 5lbs off your rotating mass)

llimonce · 06-29-2009, 12:26 PM

i learned about reducing the weight from stock flywheel.. anyone ??

Tamago · 06-29-2009, 01:04 PM

what did you learn about it?

llimonce · 06-29-2009, 01:58 PM

sorry tamago, i hear about this..

here in my country the people they do with mustangs , chevrolet a more..
reducing the weight from the back side of the flywheel .. opose to the disc surface

if you can find a shop who can lighten your stock flywheel for you safely and inexpensively i say go that route. :)

that increases power ?? .. increases vibration at iddle ?? because i don´t like vibrations at iddle

Thanks again

Mine doesn't vibrate, it shouldn't. Increase power? Not horsepower directly, but helps with increased responsiveness, just like the pulleys do. Your car will feel like it "wants to go", for lack of a better description. The tech heads can describe it a different way, I'm sure.

The only time I've ever experienced a rattling in this area was with a multi-plate clutch (not on Yaris). I think having a rattling flywheel is a sign of malfunction.

i think the same opinion

Remember that is not just a matter of reducing weight... where do you reduce it is very important...

When talking about inertia and rotational mass... the weight on the outer side of the wheel is the most important.

I've seen the OE flywheel of these cars and there is some material that could be remove... but really not that much and almost non near the edge...

You have to be SURE the machine shop knows what they are doing... if they go crazy on the wheel it could break at high speed... not nice! (google broken flywheels)
Also make sure they balance the wheel to at least the original values...

Too much risk IMO

If you really want this, go buy a Fidanza.
