I'm certainly not taking anything away from any of the prod class drivers...I'm sure they are worlds more talented then I...
But, in that class it can be more about money....

T3 and SSB are nowhere near as competitive as spec miata....

If you want to compete against the best drivers in the nation at the amatuer level then spec miata is your class.

Everyone is in the same car (essentially anyways), making similar hp, same tires, same suspension....it really comes down to the driver in SM more so than any other class, except perhaps SRF...

But, the deepest talent pool you will find is in SM.
