I would run the supermiata organic if you think it will hold your power... 290 ft. lbs of torque.

Im just not a fan of ceramic puck clutches if I can avoid them.

Gotcha, I'll have to think that one over. Why do you avoid Ceramic Puck Clutches?

They are generally like an on-off switch. Not really what you want for a road course car which it sounds like yours is.

Yea understood. I'm in mix use. Maybe 30% track, 70% nice roads.

I am running ceramic pucks in a mainly road car, some track. Bastard stuff, as said very on/off, especially bad in stop/start city work. I just slip it where necessary, the sooner it is stuffed, the sooner I will replace it with something more suitable. I did find that careful bleeding of the system with fresh fluid made a big difference in smoothing out the action, improving the smoothness of the bite.

Thanks for adding that input. Nice to have more feedback. It's a big job for me. What clutch did you get?

Would you change the rear main seal while in there? It probably has 2000 km's on it.

It's an Xedy on a light flywheel.

I'd leave the seal alone unless there is a reason to touch it. No leak, no touch!

Well, transmission is out. What do you guys think?

The wear here looks strange to me. Some of those fingers are slightly out of position. There is some wear into the surface.

The attached video makes me nervous. Why is there so much movement in the transmission?

That movement of fork and input shaft is normal.

If you have made any adjustments to the pedal for the FM clutch, be sure and go back to OEM pedal and pushrod positions for the Supermiata clutch.
