Since my "trick" Stage IV clutchmasters took a crap -I need a real clutch -Going to a bigger turbo in the next few months , plan on having 475+ whp-The twin disc says it's good for 500-750 h.p.-AMS says to use the twin Carbon-Any personal experiences out there?
Thanks for any input
-Frank

 

How long did the clutchmasters last? If money is no option the carbon is the way to go.

 

Only about 17,000 miles-There is about a $800 cost difference between twin disc cerametallic & carbon-? is if I really NEED the Carbon

I know more is always better right? Too much is never enough?

 

i have the cerametallic exedy twin disc. so far it has held up pretty well. peddle pressure is right around the same as stock but it holds a hell of alot better. a friend of mine has the same clutch and is pushing over 500 awhp with no problems at all. hope this helps

 

twin-dizzle is good.carbo/carbo is ultimate hott sauce though

 

both cerametalic twin disc or carbon twin disc are great choices. I am currently just using the cerametalic twin disc setup, and has had it for over 20k trouble free miles. It is one of the best street-able twin disc setup IMHO. However I would like to try carbon/carbon setup someday before I can comment on it.

I wish I am a baller.....

 

the Cusco twin might be the best compromise...slightly more $$ than the Exedy, but less than the full carbon/carbon, and uses carbon-metal mix disk vs the Exedy ceramic-metal mix disks

 

Based purely on my preference... I prefer the Twin Metallic. I have driven almost every clutch we offer, and on the Evo, our Twin Metallic is best for a true street car.

Carbon is awesome, however it does require heat to hold it's maximum power capacity... a lot of heat. It is not always ideal to heat a clutch when say, you're driving on I-696 and a Covette pulls up next to you.

Anyhow,I will ring you next week and you can feel it for yourself.

 

Adam,

You are the man - but not on this one.

The Cusco Carbon and the Exedy Carbon are identical, except for the fact that the Cusco cover is blue and the Exedy is Purple. Same clutch material, same pressure plate, same flywheel.

We call ours "carbon-metallic" at times because in Japan and full Carbon/Carbon (carbon intermediate plates) is offered.

Hope this help...

 

This is comparing twin disc carbon, not twin disc cera-metallic, correct? Now I'm more confused then before

I will have my Exedy twin disc cera-metallic on Monday, installing it Wednesday, along with the "white rabbit" turbo from Forced Performance-With "only" about 400whp on pump gas I figured this should be plenty good enough

Or maybe that isn't a good idea Because the clutch will need 500 mile break in?

Matt, still want to hook up with you-I'll talk to you next week-Hopefully Monday before I get my clutch installed

 

I'm really confused about these two clutches. From what I have read previously, the Cusco "carbon" has discs that are a blend of carbon and metal, whereas the Exedy Carbons are carbon discs with metal plates. Also, the Exedy carbons are much pricier than the Cusco "carbon", even though they are both made by Exedy Could you please clarify this!!!

 

I should have said Exedy uses ceramic-metal mix, not carbon-metal (unless thats changed now?)

its simple :

Exedy Twin (std version) uses ceramic-metal mix disks, metal plates between disks
Cusco Twin uses carbon-metal mix disks, metal plates between disks

Exedy Carbon uses carbon disks, metal plates between disks
ATS Carbon uses carbon disks, metal plates between disks
RPS uses carbon disks and carbon plates between disks...hence why its the most expensive

Cusco does not offer a full carbon disk clutch for an Evo...only for STi, Z, and some other cars

 

Ok - I must clear this up...

The CUSCO and the Exedy CARBON are the same Material, with the exception of the color. We do not produce a different clutch for Cusco, nor do we produce it to "thier specs".

The Exedy Metallic is a different friction material (ceremetallic) which is not carbon.

It goes like this...

Stage 1 - Organic, Full Face, Sprung, Single Disc
Stage 2 - Ceremetallic, 3-Puck, Sprung, Single Disc
Stage 3 (aka Hyper Single) - Ceremetallic, 6-puck, Sprung, Single Disc, Flywheel
Stage 4 (aka Hyper Twin) - Ceremetallic, 6-puck, Sprung, Twin Disc, Flywheel
Stage 5 (aka Hyper Triple) - Ceremetallic, 6-puck, UnSprung, Triple Disc, Flywheel

CARBONS
Hyper Single Carbon - Carbon, Full Face, UnSprung, Single Disc, Flywheel
Hyper Twin Carbon - Carbon, Full Face, UnSprung, Twin Disc, Flywheel
Hyper Triple Carbon - Carbon, Full Face, UnSprung, Triple Disc, Flywheel

HOWEVER - The Carbon Twin and Carbon Triple are offered in "High Clamp Load" ("HBMC") which hold additional power, and offer a slightly heavier pedal.

The Carbon Material is 100% High Friction Carbon... I can get more detail of the actual material (heat coefficients, weights, etc) on Monday.


Adam...You have now regained "the man" status.

 

not to hi-jack but i have the Exedy twin Metallic and I love it, but what exactly is the noize I hear only when I push in the clutch?

 

I just got Exedy Twin ceramic installed. It shifts and bite much better than my previous two ACT clutches. Also, it seem like my problem shifting fast into 4th gear at high RPM is gone but I'll confirm that when I go to the drag next time. I'm currently breaking it in.

For your info, my car is pushing 415 WHPs with GT35R miminal tuning (SAFC-II) with 21-lb of boost. The clutch, in my opinion, is matching better with the power than my previous ACT. Hope it helps you in getting the clutch.
