Review of GT Motorsports Exedy Twin Carbon Sprung Hub Clutch and Flywheel
Ok, first of all, this thread has all the basic information on the clutch, including my preliminary review, quoted here:
So, after the track day, I honestly don't have anything much to add.
The clutch withstood all the abuse I threw at it, including downshifts at 125 mph at the end of the front straight, and max torque/hp runs up the front straight. I was using it very heavily all day, and it never complained, not even once. For reference, I have 355 ft-lbs at the wheels and 363 rwhp in my JWT TT G, so the clutch was taking a beating. It felt like stock all day, with no problems whatsoever.
If you can afford it (because it is a pricey clutch), and you are going forced induction, I highly recommend this clutch.
Attached are a couple of pictures, pre installation.

Well, I just had this clutch installed on my G, and I'm waiting for an upcoming track day to give a full review, but for a very short review, I can say the following:
Pedal effort is about 110% of stock pedal effort. In other words, just slightly more.
Noise is same as stock. No idle chatter, no extra noise, no nothin'
The engagement zone (area where you can slip the clutch without it being fully engaged) is about half of what the stock clutch is. It's not an on/off switch like some high performance clutches, but there is not as much give in it, compared to stock, either.
Clamping force is awesome! My stock clutch was slipping with the JWT TT kit, but this will grab hard! I haven't dumped the clutch from 5k rpms yet, since I am still breaking it in, but I bet it will grab that hard. No slippage at full throttle in any gear.
All in all, it's a great clutch; when I get a full review together, after the March 9th track day, I will link to it here.

Dude, it's PINK, thats a little girly Where did you go to the track at? I would love to try the clutch out sence I am kinda local to you. It is tough to find a good streetable clutch that "feels" nice.

It's actually purple, but who cares?
And it was the track day at Pueblo Motorsports (PMI) hosted by Nissan Sport magazine. Should have been there, it would have been great for a sedan to be there!

At 355 ft-lbs at the wheels and 363 rwhp this clutch better hold up at the track. Even my stock clutch can take the abuse at the track at 370 whp/wtq. We need a higher HP car to test it even more. Thanks for the write up though.

Not any more so than the stock clutch does. Like I said, the actual engagement zone is smaller than stock, so if you miss that, it will shudder and grab, but once you get used to the size of the engagement zone, it's all good.

I have an Ogura Racing clutch and it makes this "Ching" metallic sound when the car fires up. Does the exedy do that? ZCG did the install so I don't think there is anything wrong with the install..
does the exedy make a similar sound?
don't know if I should start a seperate thread for it but here's my link for my ORC

Injectors are pretty close to maxing out, so this summer, a boost controller, 550 injectors, and maybe a fuel return system.
