The FM holds the torque just fine. It's a fantastic street clutch.


It's the heat of track use that it can't handle.

Surprises me that the FM 1 doesn't hold the torque, she is rated for 319ft/lb thats over 450Nm!! That's alot !! When I see that a standard Greddy makes "only" 170ft/lb and at 10psi it should turn around 240ft/lb ... strange
My 6 puck act is nearly exactly the same pedal feel as the extreeeeme organic disc. They use the same pressure plate so I suppose that is why the feel the same.

Get the FM. It will be plenty strong for your needs and more.

When I asked FM they said they've sold lots of clutches, but don't really have reports either way from miata turbo drivers that track frequently.


The solution will come in the form of a 4 puck. Just haven't gotten to changing it yet. The fm1 starts ok in the morning, but when it gets some heat into it, it slips. I've got a little 1.6, I'm not making Y8s torque here.
Thanks for the info. I guess I will try tracking my car with it in the fall and see how it does. I am going to be upset when my FM2 does not work right. I guess it will be a good reason to save up for a twin-disk from 949.
