at track speeds in open air, even an original miata cooling system should keep the car nice and cool.
Going 70/30/WW may band aid the problem but it sounds to me like there is something else going on.
Thermostat is cheap to replace but they are designed to fail open, i doubt thats it. (and if it failed closed it would have pegged the temp)
Was the engine detonating at all? Rocks in a can?
can you check/set timing on the 99 engine?
