I can not recommend using Clutchnet organic discs in our twin. I will decline to elucidate. Just don't.

That is good information. Thank you. My local shop was very helpful and resurfaced my discs for very cheap. Cheap enough to experiment.

Would you go into detail in a private conversation? I may send an email your way.

Lol, did you get alittle loose on the top end in that video? Looking forward to setting up flat shift in my car, sounds like fun.

They have nothing off the shelf. Probably could call them.

PTT Is/was the supplier for Competition Clutch, and looks A LOT like what 949 currently offers. They do list the Miata in their parts catalog.

Same spline as the RX7.

Nononono no its not.

Miata is 15/16 OD.

From what I've seen the TurboII Trans has a 1" shaft the others are 15/16" same as the Miata.

Call them up and end the speculation......

Naturally Aspirated FC has 1x22 spline and Turbo FC, FD, and the RX-8 are 1x23 spline.

I'm going off of what Mazdatrix has listed on their racing clutch section, they must be wrong then.

aidandj 12-31-2015 02:39 PM


Some splined input shafts have actual measured outside diameters (O.D.’s) that vary slightly from their commonly named O.D. As a result of this variation PTT uses the term ‘Nominal O.D.’ to refer to the commonly named shaft O.D. To determine what spline is on your input shaft, carefully measure the outside diameter of the splined section of the input shaft and compare it to the column labeled ‘Actual Measured O.D.’.

-B series is 1x22
-PTT was not involved in the development of our twin
-I took an existing CCI twin disc system, significantly lightened it, changed the geometry for out twin.

I have contacted most of the companies that should be able to make a 7.25" organic. None are able to build a bonded disc in the correct thickness with the right type of hub that will clear everything. I hope that changes at some point because I miss the twin organic setup in my cars. The ceramic twin is much harder to launch and drive smoothly.

aidandj 12-31-2015 03:30 PM

Why does mine work? Is it a company that used to make the organics, that doesn't make them anymore? Or is it because mine is riveted on, which means it isn't as good as a bonded disc?

The organic is amazing. Easy to drive, etc. I'm slightly worried about longevity. I'll pull it in 10k and see how much wear it has.

If your organics were sourced from us, they are discs that are no longer available in the configuration that meet our specs.

I believe mine were originally from you. They had to be resurfaced with new friction material to work for me.
