The transmission is garbage, that is known, the trans cooler was an attempt to make it last longer but it makes no difference since the issue is case/shaft flex that leads to bad gear mesh that strips the teeth off. The diff gets hot but so does the twin diff. Regular fluid changes are needed in any track car without additional coolers, NA & NB included as much as people like to ignore it. That said, as mentioned by someone else, the ND has a LOT more power than any of the prior Miatas, of course it needs better cooling.

Stud kit was developed by Mazda Motorsports, for the record. They switched to the SADEV on the Cup cars for a reason... the stock trans doesn't hold up.

I owned an ND for quite a while. I'm familiar with all of the weaknesses and not weaknesses.

Thank you for this. Aside from the trans, is the ND miata (1 or 2) in general reliable from a track use perspective?

Extremely.

I personally *hated* the Brembos, totally worthless upgrade. The Recaros were great at least.
