Has anyone had any experience with those carbon fiber clutches? First-hand, or second? It's supposedly a wonderful product that gets more holding power the hotter it gets... sounds like snake oil to me... I love carbon fiber and would love a light/strong clutch that loves to be abused, but I can't find much of anything about them on this site. I know there is ATS's carbonetics, but it is expensive.

Any Input?

my recommendation: don't get a clutch because it is made out of a "cool" material.

what mods do you have to necessitate a better clutch?

I'm not in need of a clutch, I'm just curious as to why there is little to no discussion about it. It's not exactly new technology, and I've seen a number of high powered Supras and Skylines use them in drag racing.

I'm not talking about some "cool" bling for my clutch. I'm talking about a product that is "supposedly" stronger, last longer, with comparably less pedal pressure, better heat tolerance, better resistance to warping, and street-able.

If something is so great, I'm curious why no one has tried and reviewed it for the STI... Is it because of the price?

I've been thinking about getting the Tilton carbon/carbon- not just becuase it is made out of a cool material, but becuase it can pretty much handle everything you throw at it.

Right now, I am only stage two, my long term plans are a cosworth or AXIS engine to go with a Full-Race kit.

I like to buy things once.

I've read that the tilton gives awesome drivability-feels like stock- and incredible wear- last forever.

Here's a short review I found (The guy loves it, even though install of the master cylinder wasn't as straight forward as you would think...) :

i dont think they make full carbon fiber clutches do they? i think its carbon ceramic or some thing like that not carbon fiber. if there is such thing as full carbon fiber clutches i would love to see the link and read about it. any links?

Here's a link to review from a vendor of Ats's carbon/composite clutch:

thanks for the link but im good lol. i dont know why but i just cant trust carbon fiber being a clutch. i would like to knwo how they are maid also. are they made like cf hoods? by cutting out the parts, vaccum and oven and all that stuff or different way?

I liked my RPS, wonder how it compares to something like this. I don't think clutches are made from carbon fiber but a composite like mentioned above? I don't see how it would be.

I am guessing they are similar to the braking systems in most jet aircraft, carbon on carbon as well as brakes in alot of new supercars(zr1, ferrari, lambo, etc...). They wear really quickly when cold, but the wear level decreases as the heat comes up. I dont know if this is good for a daily driven clutch as you wouldn't get it to the heat required for it to not wear really quickly. The wear issue has something to do with the fact that when the two plates of carbon heat up they actually transfer material between themselves, but when they are cold they dont have the heat to accept the material being given off by the other side. I think they would be good for drag racing where you slip the clutch alot and it would actually help it last longer, but for an every day driver car or even a road racer, I dont know how long they would last compared to a traditional clutch.
