I was recently at inlinepro and one of the guys there was using an Exedy twin disc as a $3000 paper weight because it was not rebuildable. It was a twin disc for a k20. I'm thinking about going with the Comp clutch twin disc. Keep in mind they use the Comp cluch twin in their street car and track car if i remember correctly.

hi guys --
There is an important distinction to make when comparing multi plate (including twin disc) clutches, especially carbon clutches.
The Exedy and Carbonetics clutch meshes carbon discs with steel mid plates. This does not work - as others noted above, this results in rapid warpage of the steel mid plate. The warped steel surfaces act like a cheese grater, eating away the carbon disc. I experienced this same problem myself in the past before our product was developed.
The ScienceofSpeed clutch is the only clutch other than high end racing carbon-carbon clutches like the Tilton triple carbon clutch which properly meshes carbon-carbon friction liners with carbon-carbon friction liners. This is the only proper way to take advantage of carbon-carbon's unique low kinetic friction and high static friction properties to achieve a clutch that holds big power yet is actually streetable.
The price of our clutch is actually quite reasonable and less expensive than carbon clutches from Exedy and Carbonetics. In addition, we retain the use of the factory master and slave cylinder and does not require a conversion of the factory hydraulics. Retaining the factory cylinders means less cost, complexity, and reliability. While it is more expensive than other organic or ceramic multi-plate clutches, when you realize how much easier the clutch is to drive, you'll soon understand that the slight increase in cost compared to an organic or ceramic clutch is well worth the cost. High horsepower tuners such as Mase, and race S2000 owners such as Rylan / Krazik are installing these clutches for the benefits that they provide.

Do you know if CC offers cerametallic disc's with their twin? This is the clutch I am going to get if they do.

Yeah, the CC has been proven and the price cant be beat IMO. I just need to know if its offered in cerametallic disc or not. I've PM'd Ya a few times on various questions (not pertaining to the CC twin clutch) but have not recieved any answers back. This has happened to me several times. I dont know if they are just really busy or starting to getting shady and not wanting to answer some questions. They should always PM people back, regardless of the questions, if they want to keep a good reputation. Its just part of business and helping people and the community out.

Could you tell us the TQ specs on this clutch? Also, what about the wear characteristics? Will this clutch hold 600-700 wtq and still be able to last a long time with street driving all the time? What would the mileage be out of this clutch, being that its carbon/carbon, when pushed to over 500 wtq? I am also leaning towards this clutch. I'm up in the air over this clutch and the CC twin that IP uses. I do like the fact that it retains the factory hydraulics and the such.

If you ever have a ? for Inline Pro best thing to do is call. They are always there to answer my ? and I just found out that I can get my CC Stage 4 clutch disc replaced for only $140......come on how great is that. I think it's funny how some have zero ability to drive with it and others like me love it.

Hey thanks for the useful input Chris! That is exactly why Im still considering the clutch you guys offer over a CC. But at the same time to a point it comes down to whether or not I want the car back on the road now or in another month. And its been NINE 
.
^^Im sure they are busy at Inline but I have never had a problem getting a PM from them, and as Ian said they Always pick up the phone offering the best answers for any question. Here is their number if you dont have it already lol 703-455-5805
Im hoping to get more input from any other members that are possibly using one of these clutches. I was talking to a friend that just made the stock block 1/4 mile pass for SRT4s and he is using an ACT twin. I could not find such a product for our car on their website, but then again the CC twin disk isnt on their website either
. Im just searching for as many options as possible. After the disk life has worn out on per say the Comp twin, would it not still be possible to have a transmission/clutch shop such as the one that rebuilt your(Ian) 6 puck make new cerametallic disks for it? There is a shop locally that messes only with clutches so I suppose I will give them a call today before I go to work. That would be an amazing option

yeah, you won't find the twin disk on CC website b/c they don't technically make it for the S2000. They make a twin disk but you have to go from the current hydraulic system to a hydraulic bearing. The guy at CC said he will only sell them to IP b/c they are actually offering the kit with the correct bearing. If that bearing fails and leaks fluid all over the clutch assembly then you will be taking your trans out to clean up the mess and probably replacing disks.
