Kevlar linned clutch ?

[deuginthesky]

Hi Everybody,


Has anyone here experienced a standard clutch mecanism but fitted with kevlar linning ?


If so, what was the cost and did you feel any change ?


Thanks in advance.

Do I have to conclude that all TVR owners have standard clutches ?

Kevlar for a clutch? Would that be a good idea? Would there be enough friction to get good drive without any slippage. Would the kevlar cause wear on the flywheel?

No need to change these kevlar clutches as they never wear our. Flywheels are only good for 10,000 miles though!

Kevlar gives much better friction than the standard linning, and is much more resistant to heat.

It won't cause any wear on the flywheel, the kevlar linning is especially developped for cltuches.


I Thought that with all clutch breakings I read on TVR, someone had already tried.

Quite an old thread, but for curious people, here is an exemple of a kevlar linned clutch made for a friend, this one fits on a Mk2 Clio V6.




May be that kind of linning will help TVR's owner to keep their clutch and engine wheel alive longer.

Interesting, I would have thought that a Kevlar based clutch lining would confer the same sort of advantages as with Kevlar brake pads (i.e EBC green stuff etc) - for those of us who think they are a good thing (see previous threads). Considering that a clutch is fundamentally a type of disc brake, a suitably devevloped kevlar based friction lining would give; high heat tolerance, fade resistance (equating to low slip when punished), minimal dust production and IMHO low wear on discs etc / flywheel.

I for one would be very interested if such a thing were available. Is this a possibility?

I'm currently having my Cerb clutch redesigned and rebuilt using kevlar friction linings have a look here for the saga !!!

That is exactly what it is about, less agressive, better friction quality, better heat resistance, very progressive.

I have not yet tried another solution that consist in kevlar sectors instead of a lining.
Main differences are:
-even better heat resistance.
-less progressive.


Aren't that type of clutch available in the UK ?

There are several issues:
-transport (I live in France where sadly TVR are so rare).
-lining is made according to the original disk itself to fit the new lining perfectly, so that a brand new disk is required.
-small series (10 pieces) is required for a full kevlar lined disk.


These are many obstacles as you can see.

I'll ask for the possibility of a single disk fitted with kevlar sectors if ever you are curious about
