I have see many people asking about different sorts of clutches and what the differences are between standard clutches and HeavDuty ones. This should answer all questions between the most desirable clutches.

Choosing a clutch for your car will be a matter of determing how you would like you car to perform. The stronger you want your clutch to be the more it will present problems in everyday drivability. Standard clutches are generally sprung-centred, full faced organic designs and allow for quite a bit of slippage in order to provide a smooth and drivable feel. Other designs such as ceramic based clutches are better suited to racing type duties and can offer very quick and strong engagement (as well as more pressure on your gearbox). This also presents the problem of making it harder to drive in everyday situations.

Organic type clutches as so named becuase of the material constituting their clutch face is constructed from carbon and other non metallic based fibrous materials. This type of friction material is popular for use in standard vehicles, thanks to its ability to handle a certain degree slipping without a massively detrimental effect on its lifespan. Organic clutches in general use a lot more friction material than a metal type plate and are very likely to be heavier than the equivalent metal/ceramic faced type clutch. (Remember the heavier your clutch the slower your shifting ability will be).

Organic performance clutches usually allow the car to retain the same ease of driving as found with the standard clutch. However if a stronger pressure plate is used the will be a slight increase in pedal effort. It is also important to know that organic clutch plates will begin to lose some of their grabbing potenital as they heat up. This means that if you want to drive you car hard for extended periods of time these might not be for you (this means tracking your car alot)

Ceramic/metallic clutches are typically used in performance street/track applications and offer a number of desirable characteristics when looking for all-out performance. If you plan on driving your car in a manner where the clutch will be placed under constant stress, such as on the racetrack, then these types may be well suited to your need. These clutches will be made lighter than organic plates (offering quicker shifting capability) since they can operate at a much higher temperature. Although there are drawbacks with this sort of clutch. These include not being as friendly when encountering traffic. Becuase these clutches offer very quick engagement usually also means the clutch wont slip in the same manner as a standard clutch. (this can result in wheel spin or jerking motion on take-off).

In conclusion

Organic = good for street, very similar to standard clutch but provides quicker shifting.

Ceramic = good for track because provides very very quick engagement though not very good for street as it provides little or no slip.

Hope i help some people with this post :) :honda:

A ceramic will last much longer on the street and if you find the right one will be easy to use. However to use it smoothly you need roughly 1,800-2,000rpm while slipping otherwise it will try to grab. Do this with an organic and it won't last long.

firstly acknowledge where you plagurised this info from.... page 118 of ASM issue 42....

secondly, y the are you bumping a post like this? its not like its a for sale post, nor did you ask a question....

i say minus points for copying someone else's shit, and minus more points for being a gronk :thumbdwn:

Get off your high horse...

Plagiarism requires that he is passing this off as his own. Not once did I infer that this was the OP's own work. Sure he did not say otherwise, but this is an internet forum, not a book published by him.
