I have come across several used carbon tripples. Every one of them seems to wear out one disc while the other two stay thick. This applies to exedy and ATS tripples. Anyone know why? I think these clutches just dont work that well. Certainly not worth the dollar amount. I am begining to think there are really NO good multiplate clutches on the market. With the exception of tilton carbon/carbon. I would say the the exedy twin cerametallic are nice driving clutches but from what I have seen the friction material wears very quickly. I hate shopping for clutches.

 

have you experienced any funny noises, like the sound of a sword being drawn from a sheath hollywood style? cuz that seems to be the other big problem, ****ed up noises that don't seem to affect performance.

 

I have had 2 Exedy twins, one HD flavor, and LOVE IT!! I also had the Exedy triple carbon, and ONE disc was down to no pad left, after 2K miles? I bought it NEW. Never found out why. go with the Exedy twin HD. You wont go wrong! Idrove the hell out of it, and when I put my stroker motor in, I thought I would"freshen up" the discs, but was told THEY DIDN'T NEED IT! GREAT CLUTCH!!

 

I'm somewhat in the same boat so to speak, and I'm not interested in buying a $$ clutch more than once, especially since I've already gotten 50k miles out of the stocker. I damn sure don't expect less from a megabuck clutch.

I've seen too many instances of improper wear from carbon units subjected to street use, and I definitely question their durability for the wear and tear of normal driving. If I had to buy a clutch today, it would be the Tilton cerametallic twin. Unless someone with ample experience comes along. who can show me enough circumstantial evidence to convince me that something else holds up better for 600whp, that's what I am going to buy.

 

oooh tilton makes a cerametalic twin? which success stories have you heard about it that motivate you towards that specific product?

FWIW, I don't think I've seen any clutch whereby someone hasn't come forward with a negative experience, but taking into account everything that I've encountered so far, this one seems to be a front runner.

 

I am in agreement with you that the exedy HD twin is the best bang for the buck. I still have no clue why one disc is wearing down on these carbon clutches. All three discs are attatched to the same hub so they are all spinning the same speed. If one slips they all slip. Must be a heat related issue.

 

THanks for the info. I was gonna get the triple carbon but i think i might have to go with the HD.

 

hard to get a price on that site eh? i know that tiltons are great... but sigh... seems we'll never find a troublefree clutch.

 

the exedy twin hd is not a very drivable clutch in my opinion....you have to rev higher to get moving and the pedal pressure is a huge difference from stock...It does grab like hell though but i would not buy it for city driving or if your in traffic alot.

 

It is true that if one slips they all slip, but they don't all necessarily have the same amount of pressure on them (while disengaged). If every time you shift two of the disks float free and one is still rubbing lightly it could cause that one disk to wear out faster. Just a thought.

Exedy Twin HD is the way to go... after break-in period its a dream to drive..

 

Yes that makes good sense. One disc is dragging when disengaged. Doesnt seem like much material would be removed during a shift though. There is no load on the clutch at that point.

 

I don't know if my experience is ample, but I will share it nonetheless. The stock clutch lasted 12K miles on my 250whp car. I bought the car in August and by early spring it was slipping in 5th gear. It had only been launched about 5 times.

I replaced it with an Exedy Twin Ceremetallic, and still have that same clutch on my car at 55K miles. The clutch still does not slip at all, but I can tell the friction material is almost all the way worn down. This is on a 400whp car with ~200 full launches, 2 years of autocross racing (>160 laps), and 2 full years and 43,000 miles of hard street use.

I have a new clutch sitting here waiting to go on the car. It is an Exedy Compe-R Twin Disc. It's similar to the regular twin, but has lightweight unsprung hubs and a lightened chromoly flywheel. Lookin' forward to how long this one will last - hopefully as long as the last one!
