it works thats all that matters to me, if you dont like that shatter get and auto, otherwise any clutch u will drop in to this car WILL have shatter.

Its got nothing to do with the clutch being cheap, its actually just noises/vibrations from the input shaft. The noise only gets worse if you install a lightweight flywheel, because our oem flywheel is a dual mass and it dampens the noise quite a bit.

Yours does the same thing?

Howcome this only happens when the car is very hot and not when it's cold?

Yeah and I have a lightweight flywheel so it's way worse. There's no solid answer as to why but I think it's from metal expansion due to heat.

Did it make the noise before your aftermarket flywheel? That's normal. Oem setup should be quite though

Yes your right, but i was just implying that this clutch is cheap, by the way guys ive learned how to drive without chatter, its basicaly like this get in to first and get it to 3k rpm, right be4 u get to 3k let go of gas and hit the clutch so that the car dosent have a chance to shift weight, this way u dont have chatter. Another words u take weight off the transmission and clutch it, this merge where the clutch has no weight on it to be bounsed back and forth.

Yes it gets louder, cuz metal expands under heat, and the constant noise you hear from under the car while idleing is ur throwout bearing.

Why? Cuz SPORTSCAR!!!!

The good news is, if that noise goes away or chatter, u got a problem, so listen to it as sweet sound of all is good

My 370Z SPORTS CAR doesn't chatter at all when I let the clutch out. I only have 9000 miles on it, but it's as very smooth.

If it was the throw out bearing it would do it as soon as you start the car, no matter the temperature.

Wait r we talking about the same thing? Am talking about the constant noise like rolling pebbles in a can, thats the wearout bearing, when its hot the noise is louder.

The shatter i belive is the input shaft likenyou sad, but its being damped by heavy clutch n flywheel. Right?
