Clutch Problem!!
I am going to install clutch soon. I have two choices. One is exedy organic clutch and another one is exedy cerametallic clutch. I would like to know what're the difference between them and the advantage and disadvantage of them??
Hope can get your opinions soon!!

How to recommend a clutch
This is a question I am asked very often, "Which clutch should I get?" I usually have 2 to 3 clutches in mind but since the clutch affects the way you interact with your car, a clutch seller should try as best as possible to understand BOTH buyer and the buyer's car. The general rule is the more hardcore you are the more likely I recommend a puck disc. The more conservative you are I would recommend kelvar. Action has good segmented Kevlar discs like the one pictured earlier. The reason for segmented vs. full face Kevlar is that Kevlar needs more pressure to work properly. Yes, torque holding capability can dramatically increase with different friction materials. It's measured by what engineers call coefficient of friction. The lower the coefficient of friction, the more force is needed to produce the same holding power. Copper Ceramic has one of the highest (but tends to break up under heat). Kevlar actually also has a high coefficient of friction, almost approaching that of the sintered metallic pucks.
Friction Materials
Organic
This is the most common stock lining and is fine for normal driving but should never be used in performance applications. Organic lining is basically wood (cellulose) with a polymer binder and some metallic strands. I am not saying it won't work but it won't last too long if you dump the clutch during high rpm launches. My favorite term for organic lining is cookie dough. And it doesn't matter if you have a heavy pressure plate working on it, organic is still weak.

If i only have 2 choices, one is exedy organic clutch, another one is exedy cearmetallic clutch ( three punks style ).
Which one would you choose?? And why??

I am using spoon clutch kit now. Want to try cerametallic clutch one. I would like to know what's the different between them. The questions as below:
When i change gear in high rpm, what's the different between them??
When i change 2nd to 3 rd, the rpm from 8800 drop to 6800rpm. If i use the cerametallic clutch one, will it help me to reduce the rpm dropped??
Which one is suitable for drag??
Sorry for toooo many question!!

The organic one smokes, the cerametallic one shatters.

This is a function of gearing and clutch and tire slip only. If you don't understand, try reading up on how gearing affects RPM at various speeds.

Did you read Clutch101? Organic will cook if you're launching very often. So the cerametallic one will be better, plus it has a higher coefficient of friction.

I will never use or recommend the exedy cerametallic clutch.
I have had good luck with the ACT XT-SS, but it's stiff and short movement can be a hassle at times.
The big question is ... Do you require more then the stock clutch?

My mods is Toda B cam, Toda valve spring, Toda cam Gear, Mugen head gasket, ported head, HKS CAI, Maxmi Works header, high flow cat, mugen cat-back, Apexi power fc, nology hotwire, twin power and ird spark plug.
I got 23% power more than stock. Do i need better clutch??
