I would imagine this is the case with most solid mass flywheels, can't comment on the exedy all I can say is this one is coming along nicely and the car is more nicer drive for it

At least 50 more stop and go miles and you're there Batou!

When you say lug? Do you mean letting the engine "bog down" like its pulling from a too low RPM that it would want? (Sorry language barrier lol).

If so thats not something I'm letting it do, its usually at the lowest revs before the engine starts "bog down" or "lug" if it is what I think when it chatters, only really with light throttle.

i'm sure it is - i've ordered the fx300 from jan. the main factor for me was cost, they seem to be the best value for money.

if you compare clutchmasters to exedy, i think exedy is slightly better quality:-
exedy (£900-1000) clutchmasters (£550 delivered incl vat)

flywheel: chrome-moly (5.8kg) vs. aluminium (6kg)

pressure plate: forged aluminium casting - ?firmer pedal feel? vs. ductile iron casting

i understand forged aluminium is stronger than iron/steel pressure plates, ?higher clamping pressures?

drive plate ceramic/metallic vs. kevlar/metallic up to stage3,ceramic from stage4

fidanza flywheel - aluminium - weight 5kg (cooper s) 3.6kg (one/cooper)

interestingly everyone seems to report lighter pedal feel with clutchmasters when on the clutchmasters website they state you should expect a slightly firmer pedal feel. similarly, they state you should only expect chatter with the stage 4 kits, not the other kits.

Clutchmasters.com - High Performance Clutches and Flywheels

can't find much on mini2 about the hyperexedy, i have pm'd someone that's got it. i think roland mentioned in one of the threads that it's quieter, little or no chatter. but i guess you're paying for it! and the pedal is v.v.firm!

Yeah that's what I meant. Rolling and staying in 2nd(not D clutching down to 1st gear). At low speed(1st gear) tight turns you can hear the worm gears in the OBX doing there thing.

You have to really listen to hear the chatter in mine. I was told that when replacing a worn clutch, the pedal will be lighter. As I had everything else replaced in the gearbox with new parts, and everything has been greased, then that wouldnt surprise me.

[batou]

Gave a bit of stick yesterday (now i'm over 500 miles on it) and there might be little a bit of slip in 1st but then again my tyres are worn so more than likely wheel-spin (max revs on launch were 3000).

Also I was stuck in stop start traffic on an exit ramp yesterday (failed lights) and made a habit of putting it in neutral and clutch out at every stop, however as I got further up the hill the clutch was feeling slightly shorter and slipping a little. Once I got moving on the next bypass there were no problems at all... weird.

Bhozar, my crankshaft vibration damper is worn and made some noise previously. Maybe this is amplifying the chatter somewhat, you can hear the flywheel rattle when the engine slows down on overrun too.

I wonder if a worn crankshaft damper would cause more damage than no crankshaft damper? If its not 100% true and balanced, I would be worried about it.

Hmm certainly is food for thought, Chris didn't think it was bad enough to warrant immediate attention but more likely to get done when I next get some work done.

Personally, I would be more worried about a balanced crank pulley, than an undamped crank pulley.

My clutch finally gave up today, I am going to ring Jan today (when its not 5:35am his time) I am although slightly concerned about the lightened fly wheel, is the chatter loud? or is it just there?

Am I worrying about nothing? also is there any idea of the life of the FX200 clutch?

Thanks

The flywheel does chatter, but only when in neutral. Personally, I rarely notice it these days, and if I do I usualy hum the Airwolf theme tune (Sounds a bit like a distant helicopter)

I'm still very happy with my FX300 and love how free-reving the flywheel is. I dont have a problem with RPM dropping when changing gear, but I am a fairly quick changer.

when I had mine done, I decided it was a good time to get think mini to also fit a Quaife ATB (LSD) as the gearbox was out. Which might be worth considering. Just make sure whoever fits it uses quality diff bearings like TM.
