Ok, so I know everyone here recommends the Exedy Twin HD and all, but I was wondering if anyone has put the carbonetic twin disc clutch in (either 1100kg or the 1350kg version). Also, have a few questions:

1)does this clutch come with its own flywheel?

2) The website says that it will not chatter like the exedy, because it is a full floating design. Is this true?

3) how driveable are carbon discs at low temperatures...say winters in colorado?

any info will help, thanks!

 

There are members who are using this clutch, and the vast majority of them like it. The primary caution I might mention is the rebuild cost, which IIRC, is rather costly. In any case, I cannot see this as something necessary for a 350whp car. There are other clutches that cost less, and will give better longevity given the expected use and slippage you'll undoubtedly apply.

 

Yea, i agree it is overkill for a 350whp car, but I'm just trying to work it out so I only have to replace this clutch once. The car is a DD and have some more power mods on the way, but I am willing to spend 300 bucks extra if it really does mean it the car will drive better and not have to worry about it ever again. I just read some reviews and some say this clutch is loud and chatters like a monster, others say its quiet... so its hard to make a decision

 

Any multi-plate clutch with metallic/carbon discs and unsprung hubs will make noise - no way around it. The Exedy twin metallic is reportedly not as loud as the others.

Keep in mind that the clutch in question will likely not last as long as the factory clutch with regular use, and it isn't intended to fit the 'not have to worry about it ever again' plan. Again, given the purchase price, coupled with the very high cost of rebuilding it, I feel it's not the most appropriate option for your 350whp car. An ACT single will do the job, costs much less, and should last longer.

 

Thx for ur opinions, As I said before, I have some more mods on the way... gsc cams, and either FPgreen, or a 3071. I am shooting for between 380-420whp on pump, so thats what the clutch will be most likely used at.

 

Also realize that just because a clutch is multi-plate, rated for more horsepower, and more expensive does not mean it's a better clutch. To find the best clutch for your application you should be concerned with how you plan to drive it and whp goals. If you plan on launching or not.

If your under 420whp, you should be fine with a street disc, or a puck clutch if you really want something more aggressive.

Clutch is great, It only chatters when the clutch pedal is pressed but not to loud. It's gone thru 10k miles daily driven and not one problem.
Iam waiting for it to cool down so I can take it to the track and see how it holds up.
I would say go for it !! Just make sure your installer knows what there doing and
It does come with it's own flywheel.

 

Ok, but realize that I milked 60k miles out of the factory clutch, which saw 5 different turbos over its lifetime. Obviously I'm not advocating the use of a factory clutch, but my point is I doubt 25% of the Carbonetics units out there will make it half that distance - not because they don't work, but because longevity isn't their primary purpose. If longevity is your priority, you might want to do your research. Also, I strongly advise you to check the rebuild price ($$$) for the clutch in question.

 

I cannot speak specifically on Carbonetics clutches, but I know from my many conversations with Mark Conte (formerly of Titan Motorsports) that high-torque rated, multi-disc carbon clutches (ie Tilton) have excellent drivability with less noise than other non-carbon multi-disc clutches.

As for durability, there is a reason many of the insane hp Supra guys run the triple carbon Tilton, and they actually last longer with dump launches than gradual slipping. One downside of carbon is its frictional weakness, and slipping carbon on carbon generates loads of friction, hence why dump launching carbon on carbon allows for so many repeated 1/4 mile passes.

As for rebuild costs, it entirely depends on how severly the clutch discs have been worn. A typical Tilton rebuild following multiple passes at the drag strip runs about $500-700, I would imagine a Carbonetics rebuild to be similarly priced.

 

That is correct. Slippage creates heat. Heat causes warpage and wear. There's more slippage during the course of daily driving than anywhere else.


Guess again.

I've confirmed that for a Carbonetics carbon clutch, the wholesale cost for a pair of replacement plates alone is well over $1000. This doesn't include any service to the PP, flywheel, etc. This means when it's time to rebuild the clutch, one will essentially be paying for a new one.

 

Well there is chattering only if its pressed and not too much...
As for daily driving its ok,i mean its a bit hard as compared to my pervious clutch HKS GD MAX but it holds great!
I have had hard launches around 6000 to 7000 rpms with out any prob!
Conclusion:Great Clutch!

 

Wow very interesting! That is quite a difference from the Tilton pricing, which is from the mouth (or keyboard) of Mark Conte, former parts guru at Titan. He said Titan has all the Tilton triple carbon clutches prepurchased through 2008 for the Supra guys.

Either way, I suppose once you have the money for a $5,000 clutch, you can afford a $1,000 rebuild.

 

This is why (as I've learned), the rebuild cost is an important factor when considering a clutch. With a Carbonetics clutch, the rebuild cost will be close to the purchase price of a new one, because the replacement part prices I quoted are what dealers pay, not retail prices!

Tilton's (and probably others) rebuild pricing is more friendly, and is even more reasonable with metallic clutches.

Just some frequently overlooked FYI.

 

Ted,

Definitely good info to have either way, and you're absolutely right, it has a lot of influence on which clutch kit to buy.

I am actually prototyping a triple disc kit for the EVO as we speak (both 5 and 6-speed), with the expertise of Bill Pettigrew making sure fitment is within OE spec.

Primary contact disc is likely going to be kevlar, other two discs are TBD. I don't want to say too much about it with respect to "vendorship," on the forum, but pending test results I will hopefully become a sponsor and offer them to the forum.

 

Figured I would give you a heads up in case you have been emailing me and being ignored:
