Difference between OEM Clutch and Aftermark Clutches...

[Gerard van Santen]

Can somebody tell me the real differences between the OEM Clutch and Aftermarked Clutches?

And how much Horse Power and Torque can the OEM Clutch have?

I think the biggest differences between stock and aftermarket is takeup points and how stiff the pedal action is. The other major difference is most aftermarket units are "rebuilt" and will probably not last as long as OEM.

I think the OEM will handle most forced induction mods out there right now. It really depends on what you are using the car for. Drag racing (or street racing) would be better served by an aftermarket unit. Personally, for street use or road racing circuits and the ability to match revs (heel and toe), any of the available units will work.

Just for comparison, I have the OEM in my street car, which was run on the track my first year of experience. My present track NSX has the Dali ACT clutch. Slightly smaller "sweet spot" and much quicker take up. Whereas the OEM unit does not engage until the pedal is almost all of the way out, the ACT unit engages almost as soon as you start releasing the pedal, which is nice at the track. HTH.

Thanks ncdogdoc,

What about horsepower limitations?

And difference of friction material?

This was even more so with the aftermarket clutch that I tried (I think it was a Centerforce). There was virtually no "sweet spot" and it felt as though the clutch was either in, or out, with no progression in between whatsoever. It was very difficult to shift gears without the car bucking (like it does for someone who is just learning how to use a clutch, which I wasn't).
