2010 Mazda MX-5 Miata

We’re borrowing a new MX-5 from Mazda and working with our friends from The Tire Rack to build it for competition in the new STR class of SCCA Solo competition. While many folks consider the Honda S2000 or Toyota MR-S to be the car to beat in this new class, we wanted to see if the MX-5 can be competitive. The MX-5 slots right between the two class favorites, offering lower weight than the S2000 (but more than the MR-S) and more power than the MR-S (though less peak horsepower than the S2000).
