I've been looking for the difference in torque ratings on each of the Exedy twin plate clutches excluding the Carbon Fiber series. I can only find specs on the twin plate that is offered in the U.S., but nothing on the 2 models offered across seas.

U.S.Exedy USA Rep told me Part Number: ZM022SD can handle roughly 480 foot pounds of torque.

Anyone have info on the other 2 models offered in Japan:

Exedy - Hyper Metal - Compe-D - Twin Plate
Exedy - Hyper Metal - Compe-R - Twin Plate

I used bablefish to translate the japanesse pages.

Any info would be appreciated...



(Mods if this is in the wrong section please relocate it to the proper section..)

 

well i didnt call and speak to anyone personally but here is a link that leads me to believe...
comp D twin = 680 torque
comp R twin = 750 torque

the comp D is claimed to be used for Rally and Ghymkana/autocross generally
the comp R is claimed to be used for Circuit and drift applications.

here is the link take a look. This is a general table for all cars not FD specific.

Thanx CircuitTheory, but do you have any idea what materials both clutches are made of and if they are soilid or sprung hub? These website translators don't do me much justice. Seems like the important information are in the pictures and the translator can't translate them..

 

Here is a pic of the comp R, you can click on the parts names and it will explode the pic so you can see how it is made. Comp R seems to be unsprong

Comp D is here and it seems to be sprung.
Since the name of the parts is Hyper Metal Comp I would think it is a metal type clutch.

Both clutches have slotted floaters (same idea as slotted brake rotors.)

 

Thank you very much, you are the man!!!!!!!!!!!!
