I switched to ITA last year from SM and Bret De Pedro switched to ITA with his Miata this year. At VIR this past weekend I took 2nd place on Saturday and Brett took 1st Sunday (I came in 3rd Sunday). The Miata is very strong in ITA if built well.

As for suspension, I found changing the bushings to be a HUGE difference. The engine is important, but really the handling is what makes the car strong in ITA and the stock bushings are simply not stiff enough. I'm still sorting the car out and need to improve my driving, but IMO the Miata can easily be a consistent ITA winner.

Oh, and at MARRS I Brett took 1st place and set a track record with his Miata.
