I know alot of people looking for new clutches shy from the Exedy because of the price, as did I for quite a while. I am damn glad I got it though! I had the Exedy Twin install back in July along with a McLeod Adjustable Master Cylinder and my New MN6 (Thanks Rodney!).

So after 4000 miles, 4 trips to the strip, here's a run down:

Pros:
Positive engagement/disengagement, no slip AT ALL EVER, grips like a SOB!
Little to no chatter.
Very little movement on pedal needed to shift (thank God!).
Lots more Pros than I can think of probably, especially for people putting down more power than I.

Cons:
Pedal is Very stiff. I have engage/disengage at the very top, and it takes very little movement to shift, I mean VERY little. I thought maybe the pedal had softened up some but after letting a few friends drive it, stall and sputter it, I realized its just that I have gotten used to it. The sweet spot for normal driving starting from a stop is specific and I hit it 19 out of 20 times, no problem, sputter rarely and have stalled it myself only a handful of times. This includes being stuck in bumper-bumper for hours.
It is way more expensive than most, but I really think this is a good case of you get what you pay for. (And we know more expensive is not always better in this business).
Lack of time in market. Now you hear good things and bad things about some other clutches, but being fair, alot of the better known ones have had more exposure to the C5 market for a greater length of time, so time will tell if the Exedy lives up to it all, and I think it will. It would be better if some of the 9 and 10 second guys were running this and chiming in more, but I have not yet heard of anyone burning up a Twin. Now if after I put in the S/C it goes after one season, then maybe I was better off with the SPEC V. But as I must pay someone to replace my clutch, and seeing just how hard that is with headers on, I like the idea of paying double the price for the clutch that lasts at least twice as long, and only paying for one install.
NO OTHER CONS!

That all being said, here is my standing offer:
Any corvetteforum.com senior member, that is 25 or older(insurance), that has owned a C5 for at least a year and is going to be near Dulles Airport near Washington, DC can shoot me an email and if we can arrange a time I would be glad to let you take it for a spin, with me in the car of course. If you really want to get on a few launches, bring your own rubber!

I have nothing to gain by this, I don't work for Exedy or any person or firm that sells it or any automotive product. I just think it would have been nice if I could have tried a few clutches out before dumping in so much money, so here I am trying to help. All I will ask is that you post a reply to this thread stating honestly what you though of it. And not to damage the car of course!

Please don't PM me, email is much better, thanks!

 

WOW...now that is a loyal CF member Nice offer!

 

I'm going to shoot you an email right now -

I am going through this decision as we speak

 

Hey, I'm going to be in Indianapolis later this week - maybe you could meet me at the Speedway parking lot. It's about half-way between DC and LA

 

Ruby,

Don't even think...just do it. My car is going to ECS next week and getting (among other things) the Excedy Dual. I have just had it with the stock clutch and decided, based on so many recommendations to bite the bullet on this one. And here we have an unsolicited offer from a member who is so sold on his Excedy....I know I've made the right decision.

Did you update to the later 2002 z06 hydraulics and do the drill mod on the slave?

THat will drop your pedal pressure significantly

I burnt up a development twin, but not the production version with my TT car..

And Agree, its manners are hard to beat on the street.

I love my Exedy Single Hyper clutch!

 

Its all in the transmission

 

I have the LS6 slave with bleeder extension (got it packaged with my Twin from Tom at Carolina Clutch). Still stiff! Stiff compare to what though is the point, I have had the LS1 and 02 LS6 clutch only before this, so I readily admit that I haven't driven any of the other usual suspects. Thats the kind of feedback I am trying to get posted on this thread by others. Just to set the record straight.

 

I replaced everything on my 04 Z06 when I had the Exedy Hyper Single installed; T/O bearing, slave, pilot bearing, bleeder extension line added and had the drill mod done.
At first the pedal feel was heavy or stiff, depends on how you want to describe it, but after 500 miles it got lighter or softer and to me it feels like it should. What I mean by that is that for me it feels balanced between pedal engagement and shifting which allows me to make better and smoother shifts.
I know this may sound funny to some, but that's what I feel.
Because the overall clutch is lighter in weight and the diameter is smaller, the car of course revs much quicker to red line.
I'm still in the learning curve of this clutch and it gets better and better each time out.
For my application, the single was the one Tom at Carolina suggested.
I don't know If this is the feedback you are looking for but my .02 worth anyway.

 

I want to add my 2 cents worth now that I've had the chance to take Flubyu up on his generous offer to test drive his car. I think my comments are perhaps useful only because they come from someone who has never driven a car with anything other than a stock OEM clutch.

I did not find the clutch pressure overly hard. While it has been 9 months since I had driven a Vette (I sold mine in Jan.), the clutch pressure of the Exedy didn't seem that much higher than my old stock Z06 clutch. It certainly was not uncomfortable.

However, the clutch sensitivity was much greater than stock. I stalled the car several times when I first tried to get rolling, and that was while I was trying to be very carefull not to add in clutch too quickly. Even though I had difficulty in the beginning, I quickly got used to the clutch and the need to bring in the gas more rapidly than I was used to. After driving about 30 minutes, I felt pretty comfortable from starts.

My only remaining concern is whether or not I'd want this clutch in heavy stop and go driving. Again, the issue is not the pressure but the sensitivity and the need to bring in more gas than a stock clutch to keep it from stalling. This would be tiring and perhaps a tad risky if I could only move a few feet at a time due to stop and go traffic.

Finally--and very importantly--I want to thank Flubyu for meeting with me and letting me drive his great car and get a feel for his Exedy clutch. He is a super guy and I'm greatful to his generosity. He's an example of what makes this forum such a great community.

My clutch is in. Have not had a chance to drive it yet. Cant wait.

I heard the Cartek TT kit with over 1000RWHP is getting the TWIN to slip very badly. Waiting to see what Cartek can do with this clutch.

 

The twin is only rated, (only!), to 850, they should be going with a triple at that power. It's in the Exedy catalogue, but I have never seen a price on one.

 

Thanks again for the great test drive, and my apologies in my post above for calling you Flubyu, rather than IFLUBYU (great license plate). You're welcome to test drive my 427 if I end up getting one.
