Because several of the FI guys on the board have upgraded their clutches I wanted to get some feedback on the set-ups being run and their characteristics. Feedback on cost, engagement, chatter,driveability, etc. would be great. Do you love you're set-up and would you buy it again??

In a PM from aalzuhair who has an Exedy clutch/flywheel:
But anyway the Exedy twin carbon clutch its very smooth on engagement it does not jerky or come on too strong.

At first, the clutch pedal felt a bit harder than the stock clutch but not hard that it would be inconvenient for a daily driven car. The car does make a bit of a noise at idle and below 2000 rpm’s (some times) but once you have the car on the go it feels like stock. In heavy traffic its not harder than the stock clutch, I have not noticed any deference in driving comfort.

But I can tell you that with fast shifting the clutch do its best and this is where the money is. When I shift fast from the start the car engages some smooth that a lot of people told me that me shifting skills have gotten much better. I have received a few complements about how fast I shift without jerking the car, and I tell them it is all in the clutch.

So yes it was worth the money. I got the clutch from Ultimate Racing, which they got it from Adam at Z1 performance. They bought it for me because I asked them to get me the best clutch system available in the market for the 350z. I would rate Exedy clutch / flywheel combo at a 9 out off 10, just because I believe that nothing is perfect.

Q: How many Exedy clutches are available?
A: I think 3 are available. One plate, twin and 3 plates all carbon. But the one I have is the "Hyper Carbon Series, Semi Carbon Multi, Twin carbon clutch / flaywheel combo" it runs for about $2800 or so and that is the one your looking at and it will be the last clutch you will ever buy

Q: how much hp and tq is the Exedy supposed to hold up to?
A: Well on Z-1 Performance it says like 750hp (Idon't know if they mean wheel HP or flaywheel HP), but according to others, it can hold much more than that, however, Exedy under rates their clutch to be on the safe side.

Myself, 350ZDaKalb, and Enon Exec all went with the ATS twin disc carbon clutch and flywheel. It's the ulitimate clutch...in my opinion. If you look hard, you can find them for under $2000, and the win disc carbon can support 700-800hp and as stock pedal feel and stock engagement. As the discs heat up, they grip even more. Similar to the Exedy twin disc, but several hundred dollars cheaper.

And the entire clutch/flywheel assembly weighs about 26lbs. I have yet to drive a car equiped with one, but everything I have heard about them has been positive. With dual floating carbon discs, it will be the last clutch you ever buy.

for the money, the ATS is impossible to beat, but i wouldn't quite call it the ultimate. that would have to be Tilton's 7.5" triple carbon/carbon. course, the tilton is nearly 2 1/2 times more expensive than the ATS.

We are having a group buy special on our tilton clutches. Street or semi-street, with the 8lbs flywheel.
These are very nice setups for the FI 350z's, they will allow the car to rev up faster, thus allowing the turbo to spool much quicker. Also, if you have a SC, then this will be a good setup as well, as you are able to get up into the power band quicker (for some SC kits).

There seems to be allot more options on the ATS clutches. Does the tilton need to be adjusted or can you install it and forget it like the ATS?

Holy cow.its almost $1700 more than the ATS twin disc??? With an 8lb flywheel, it will be about 8 lbs lighter than the ATS. Does anyone know how much the Tilton full assembly weights? Has anyone ever driven this? 8lbs seems awfully light for road usage, even with a full face carbon twin disc..just my opinion.
