The NTAXS is proud to announce two new classes (X and XR)
The NTAXS is proud to announce two new classes (X and XR) for the 2013 season. Class X is open to all vehicles (regardless of engine size or induction) as long as they are using street tires (140 tread wear rating or higher). Class XR is open to all vehicles (regardless of engine size or induction), including those with tires with less than a 140 tread wear rating. This allows vehicles normally classed separately to participate together in the same class and heat. For example, Honda S2000s built for SCCA STR Solo competition are normally in a different class than Mazda Miatas built for SCCA STR Solo competition. They can now compete together in the X class. The existing classes (1-3, 1R-3R, and S2000) will remain.
