my idle is around 1500rpms and that gets rid of the cement truck sound at idle, but there is no solution for getting rid of the loud vibration sound at 2500-3000 or less if you're in too high of a gear. You'll just have to train yourself to be in a lower gear to keep the rpms high

 

every clutch with an integrated flywheel sounds like this.....it is the nature of the design. As soon as you fit a lightweight flywheel, more noise is transmitted externally rather than dampened internally

 

Unfortunately, all the lightened flywheels will have some level of "cement mixer" as many people put it. Even the Nismo and JWT have a similar sound. It is odd that some cars sounds different, even when running the exact same flywheel/clutch setup. Having heard about 6 different ATS twin discs installed, some are near silent, and some make the standard noise. Don't let the sounds discourage you ....its really not that bad.

 

Thanks for the advice Sharif. So maybe I should just go with the Nismo Clutch/JWT flywheel setup then as this is my daily driver. From all of the posts that I have read, this is a much safer option than the APS or Tilton clutch.

Thanks for all of the help guys!

 

Not sure about safer, but they can be easier to drive. I wish you could experience my clutch...I think you would be really impressed with the drivabilty even with the very light flywheel.

I will try to post a video...of some various starts and cruising at 1500rpm in 1st gear...to show you that it does jerk or grab.

 

I prefer ATS just by price. Similar quality with both.

About the clutch/flywheel chatter...that just lets you know you have a real man's car!

Thanks again Sharif. Wish I could drive your car as well to see how it feels.

 

So has anyone driven the Exedy twin plate so we have something to compare the ATS with?

The Exedy is supposed to have a sprung centre unlike the ATS which should make it more streetable.

 

The Exedy clutch uses a different, and inferior design, IMHO. ATS uses solid thin carbon discs, that are floating and aligned by a seperate center hub. The carbon discs are not attached to the hub...they are just aliged with it via splines. The ATS does not need, nor could use a sprung hub.

The Exedy uses a steel backing plate, and then carbon pieces are revited to the metal backing. The hub and disc are one unit, and as a result, it needs to be sprung. Exedy also makes an upsprung version, but still the same design...carbon attached to a metal disc.

Pure carbon disc will last longer, and be more resistent to heat, than a design which uses carbon pads attached to a metal backing disc.

Aside from Peter at APS, not one person has said the ATS was unstreetable, or uncomfortable to drive on the 350Z. Phunk has the 1350kg heavier pressure plate, and told everyone that has mom drove the car without even stalling it once!

 

Ill put up a review of my ATS triple plate clutch with the 1100kg pressure plate in a couple of weeks.

Does anyone have experience with the triple yet?

 

I'd have to agree with that statement.. it's a streetable clutch.. it can get a little hairy in some situations but for the most part it's fine..I mean I'm not planning on getting rid of it anytime soon.. I'm just going to try harder to avoid the 50 mile backups

A foreign (to the U.S.) guy had given me a review through PM a while back of the Exedy twin-plate.

I'll see if I can find it if you would like to see it.
