Well, I went ahead and had my clutch upgraded since my stock began slipping on the dyno when power got to around the 350WHP/320TQ range. I knew the stockers were supposed to be weaksauce but I thought even that was a little premature considering I have less than 2K miles on the odometer.

Come to find out there was a reason for the slippage and it was related to a faulty transmission input shaft seal. It caused fluid to leak and you get the idea. Whatever's done done is done so I figured I'd give another person's impression on the clutch that is shaping up to be the mid level clutch of choice from what I can tell.

Right from the get-go you will be able to tell the clutch is definitely more touchy than stock, with the engagement point much higher than before. You have to be more precise with your feet, but this is easily a clutch than can be daily driven from my experiences so far. 1st gear takes a little getting used to but overall this is much easier than my Exedy Triple that I have in my 350Z.

As far as noise? I noticed no chatter over my exhaust and intake, although I couldn't care less about that - I just know some others do.

The only interesting thing is that after a spirited 3rd gear acceleration onto the freeway my "Service Engine" light came on. I actually shut down the car at a red light and it came back on after the car restarted so I'm not sure what that's about. I believe I've read others that report similar things with added TRQ so I'm not overly concerned at this juncture.

In summary, the clutch grabs nicely from what I've seen so far. I have an HPDE at PIR on Friday so after four sessions I should know the clutch intimately and I'll post an update at that time.

If anyone has any questions, let me know and I'll do my best to answer...

 

Just installed mine as well. 1st gear does take a little getting used to. I was surprised how light the stock flywheel was compared to the evo viii/ix flywheels. Doubt the new assembly is any lighter than stock but at least it holds. My rear main seal was perfectly fine, just out torqued the stock clutch and was nothing left on the disc essentially. Pedal pressure not that stiff despite being the HD model. Love being able to boost again. Been limping by on no boost for a while.

 

So, I just got back from an HPDE event at PIR. This gave me four twenty minute sessions (technically three and some change due to my inability to calculate gas mileage) to evaluate the clutch.

Frankly, it performed very well. I did not go easy on it and it took everything I threw at it without complaining once. The track conditions were brutal as the afternoon sessions were during near 100 degree temperature. Although I got my brakes to fail, the clutch just kept plugging along.

Initial bite is very strong and it took aggressive shifts from my 350HP/320TQ all day. At this point I wouldn't hesitate to recommend the clutch to anyone as the only thing left to test is durability over a long period of time...

 

is your clutch master cylinder still in good shape?

 

I do not have the master cylinder sleeve but had no issues throughout the day and I definitely do not baby the clutch (including many hard downshifts, etc).

Granted, this was the first HPDE with the clutch but so far no issues...

 

I have stock MC here too. No problems so far.

We just passed the 500mile mark without too much load. Pedal feels super light compared to ACT HDSS, double bled to make sure. How is the pedal on your side?

ACT caused MS break twice, one being with the AMS ring. So I think Exedy did the trick with the light pressure plate to avoid this major issue. But its still to be tested on some decent power. We push about 460WHP @ 24psi on a GT3582R.

this is right before we broke the MS

wow with the MC ring from ams is still broke?

im glad i got a exeddy TD might have to rethink the ams ring or atlease use it unitll i can afford the upgrade

 

Yes, we were thinking of using either a IX MC or an aftermarket unit but so far the Exedy twin plate + ring seems to hold. Will let you guys know.. this was the biggest issue for us so far..

 

is this noisy? i'm wondering if i should get the exedy twin or the spec super twin.

 

all lightweight flywheels are noisy, exedy is not bad over 800RPMs, it gets noisier below that.
