This week the 33z Racing Team heads to the Humboldt Speedway in Humboldt, Kan., for the King of America IV. We will have some brand new T-shirts for 2014 on hand at our trailer all week long or you can get them at the USMTS souvenir trailer. Stop by, say hello and pick yourself up one of these awesome shirts. Available in Youth Medium all the way up to 3XL.
