clutch and flywheel advice

[16bit]

I am considering just getting a new clutch and flywheel because of this bearing issue I have. I am ok with the clutch side of it i think as I will probably get a single plate got for about 350-400 foot pounds which will be more then enough. However I am not sure if I should go for a fidanza flywheel which is about 7.9 pounds or 3.6kgs or the one that comes in the flyin miata happy meal at 10. something pounds or 4.5ish kgs. I am not too concerned about it driving like stock. is the fidanza unit good?

Fidanza is two piece and made of aluminum so thats why its lighter. I hear you can buy a new surface for them it which is good but for almost the same price you can get a flywheel re surfaced so im not sure why you would buy a new surface for the fidanza??

There are reports aluminum flywheels make more noize than one piece crmo but I have never dríven a fidanza to hear for myself.
I found the 4 kg crazy fun to drive, I'm thinking a 3.6 kg one would be even more crazy fun.

I have heard good things about the flyin miata clutch packs they are pumped out by ACT but with a frictional material made to flyin miata's specs.

what cromo one do you have?

[wun911]

ACT prolite 9 pounds (they dont make them for NA)

I had preference to the crmo I hear one piece is stronger...

hmm i think i will agree and go with that. where did you get it from, FM?

A couple of weeks ago some dude wanted to sell his ACT prolite 9 pounder...

I got mine from mx5 parts uk and it was expensive belive me it was real expensive shipping and the AUD sucked balls when I got mine....

I guess I've been called worse. Yes, I am selling an ACT Pro-lite which is an exceptional flywheel - the best I have had, seen and used. It is a perfect mate to a button clutch and high performance setup. The only reason I am selling it is I have moved to a twin plate clutch and custom made flywheel to suit. PM me in you are interested in it.

All flywheels need and should be resurfaced for a new clutch. The rotating assembly should also be balanced as well. i personally would not use an aluminium flywheel unless a scatter shield is fitted. I always use cro-mo ones like the ACT.

I was so cut when your flywheel was for sale...
I remember trying to hit and drug people just to get a lightweight crmo flywheel at a decent price.
I was so willing to pull a machete out of my country road bag and chop people just to get a flywheel back then.

Personally, I'd be worried if I had an aluminium flywheel.

I've seen them go bang, and they make an almightly mess when they do.

Stick with steel or chrome moly.

Aluminium is a brittle metal, and it is also soft.
It can get hairline cracks in it, that you would never see, then, when you stress it, it could just let go altogether.

A lightweight flywheel can be a real bastard in traffic too, especially if you have a savage clutch.
You have to rev the motor quite a bit more to get off the line, when compared to car with a normal weight flywheel and when you change gears at normal speeds, the engine seems to come to a stop as you push in the clutch, leading to jerky gearchanges.

i have decided to go with the cromo option as its probably the best of both worlds being light and strong. just need to finalise what clutch I am getting now. thanks for the input everyone.
